10 best proximity sensor

A proximity sensor is an electronic device used to detect the presence or absence of objects within a certain range of its sensor field. These sensors are widely used in various industrial and scientific applications for automation, control, and safety purposes. Here are some key points about proximity sensors:

  1. Working Principle: Proximity sensors operate on different principles depending on their type. The common types include:

    • Inductive Proximity Sensors: These sensors detect metallic objects by generating an electromagnetic field. When a metallic object enters this field, it induces eddy currents in the object, which alters the sensor's output signal.

    • Capacitive Proximity Sensors: These sensors detect objects with varying dielectric constants.When an object enters the sensor's field, it changes the capacitance, leading to a change in the sensor's output.

    • Ultrasonic Proximity Sensors: These sensors use sound waves to detect objects. They emit ultrasonic waves and measure the time it takes for the waves to bounce back after hitting an object. The distance can then be calculated.

    • Photoelectric Proximity Sensors: These sensors use light beams to detect the presence or absence of an object. When an object obstructs the light path, the sensor's output changes.

  2. Applications: Proximity sensors are used in a wide range of applications, including:

    • Manufacturing Automation: They are commonly used in manufacturing lines for detecting the presence of objects, controlling robotic arms, and ensuring accurate positioning of components.

    • Machine Safety: Proximity sensors are used in safety systems to detect the presence of personnel in hazardous areas and can trigger safety measures like emergency stops.

    • Object Counting: In industrial settings, they are used for counting objects on conveyor belts or in sorting processes.

    • Level Sensing: Proximity sensors can be used to detect the level of liquids or solids in tanks and bins.

    • Access Control: They are employed in security systems to detect when doors or gates are opened or closed.

  3. Advantages: Proximity sensors are favored for their non-contact detection, long life, and reliability. They can operate in harsh environments and can be highly accurate.

  4. Types: In addition to the mentioned types, there are other variations such as magnetic proximity sensors, Hall-effect sensors, and more, each with specific applications and advantages.

  5. Output: Proximity sensors typically provide a digital or analog output signal that indicates the presence or absence of an object, as well as its distance or position in some cases.

  6. Adjustability: Some proximity sensors allow for adjustments in sensitivity and detection range to suit different applications.

In industrial and scientific settings, proximity sensors play a crucial role in improving efficiency, safety, and control of various processes. Their versatility and reliability make them essential components in modern automation and control systems.

User questions & answers

Question: Do you need an optocoupler or resistors on an Anet A8 stock board? Or will it work if its plugged straight into the board
Answer: Just buy a jst connector (the white connectors at the end). You dont need anything else to get this working on stock anet board
Question: what are those white power plugs for the Blue Brown and Black power called
Answer: They are called JST connectors. You need the 3 slot connectors for this sensor. Here is the exact product I bought. (I needed a lot) 750 Pieces 2.0mm JST-PH JST Connector Kit. 2.0mm Pitch Female Pin Header, JST PH - 2/3 / 4 Pin Housing JST Adapter Cable Connector Socket Male and Female, Crimp DIP Kit. https://www.amazon.com/dp/B0731MZCGF/ref=cm_sw_r_cp_apa_i_RP5GDbV82M575
Question: Does this sensor turn on when it touches metal or turns off
Answer: It's a normally open and completes the circuit when made. The sensor does not touch the metal, it detects it when it gets within a certain distance.
Question: Is this sensor supposed to output voltage when not activated by metal? And if so, would that mean it is actually normally closed
Answer: On the NPN NO version, the black wire (sense) is pulled up to the input voltage via an internal 10k resistor. This is to prevent the sense wire from floating (i.e. standard pullup). So, when away from metal, it will pulled up. When near metal, the NPN transistor "closes" and shunts the black sense wire to ground (goes low).

User questions & answers

Question: Will this illum a led and send to a ext dev for when ir strikes reflective tape or connection is interrupted. I have 5 to 15 volts 150mA
Answer: Hello Jason: I think the question you are asking is: Can this device be used to trigger an L.E.D. by sending a signal to an illuminating circuit (i.e. switching circuit) if and when the built-in Infra-Red led transceiver's reflected beam is broken or interrupted by an object or obstacle placed in the path? Is my assumption correct? If so, then yes it is possible to perform this task with this device as the sensor/activator front end to either the Arduino (for processing) or an adequate momentary logic circuit and an IR reflector designed to make this happen...Kind of like an "electric-eye" type of intrusion detecting device. Hope this helps.
Question: Will these work with a Raspberry pi
Answer: The quick answer is YES, they will. The longer answer is BUT, there are not that many I/O pins on a Raspberry Pie so it would be easy to use up your pins with just a few of the IR devices. So possibly a analog or digital multiplexer would allow you to use say 8 of the IR devices using 3 output pins to select which IR unit you wanted and a pin to read the value of the IR device. There maybe some Raspberry hats that have this kind of thing all figured out though.
Question: Will this work for a 24 volt solenoid
Answer: These devices, by themselves, will not handle a 24 volt ac or dc solenoid. The output of these devices is strictly a T.T.L. or RS-232C level. You might want to interface a trigger interface that could handle the current involved, to do the job; which could easily be done. But the answer to your question is no, they cannot by themselves handle 24 volts. Hope this helps.
Question: What is the repeatability of these sensors? I'm trying to use them to measure length
Answer: You can't measure length with these sensors. They are photo-switches. The emitter reflects off the surface back into the photo-diode. You set the level at which the photo-diode meets the comparator threshold by way of potentiometer on the sensor. So how "repeatable" is the sensor - fairly under ideal conditions. You can detect the position of an object to a few millimeters repeatably, but the "repeatability" is affected by a number of other factors:1. Distance - as the distance increases the reflected light decreases (as a square of the distance - both out and return) so the sensitivity wrt distance drops. 2. Emissivity of the surface - it has to reflect the IR ligth afteral3. Angle of the surface relative to the transmitter - a smarter man would say something about solid-angles4. Ambient light - probably the worst gremlin, especially as distance increases and you drop the sensitivity. In my experience, when you get out past 20 cm, sig/noise goes to hell outdoors.5. Direction/speed object is moving - There is a bit of a hysteresis, We've never noticed any timing delay, but YMMMV.I'm sure there's more, but you get the idea.

    User questions & answers

    Question: Will this work with my AutoPage C3-RS
    Answer: This will work, on any alarm system, it is an internal proximity sensor for the vehicle. Be advised, it is fairly sensitive and bugs and birds will trigger it. Just ensure the jacks are the same, or you will have to splice the harness.
    Question: There are videos on Youtube showing how this can be added to a basic factory alarm and work. So can it or not
    Answer: It's meant for plug and play with specific DEI alarms. But you can cut the connector off and wire it up manually. Power, ground, warn away, full trigger
    Question: Can I install to factory alarm system
    Answer: I installed in the factory alarm of a Hyundai. Most alarm modules have extra pins available for accessories. This sensor uses only two pins for energy (that you can get from so many cables behind the dash) and the next two wires are to trigger the "warning" status and "Alarm" status. It should work.
    Question: Does this sensor stay on while security system is disarmed? The LED keeps blinking while driving, plus it always activates my cobra radar detector
    Answer: It depends on how you wire it, but, yes, if you have it powered and grounded while the car is running, then it will stay on all the time you are driving. In my case, I wired a relay into the ground circuit, where the contacts were normally closed when the Accessory supply was OFF. Thus when the car was running (accessories on) the ground circuit was DIS-connected and the sensor OFF.
