    5 out of 5 based on 3 reviews | Write a review
    $46.27
    Diffuse reflective photoelectric sensor consists of light projector and light receiver in one, can distinguish transparent or opaque reflective object. The supply voltage is DC 12V-24V (6-36V) or AC 110V-220V (90-250V). Infrared photoelectric sensor can be compensated for longer distance with sensitivity controller, less susceptible to interference, fast reaction, long life, high resolution and high reliability.

    Tips: Detection distance of diffuse reflection photoelectric sensor

    The effective detection distance of the diffuse reflection photoelectric sensor is determined by the reflection ability of the detection object. The specific influencing factors are the distance between the detection object and the photoelectric sensor, the color, the size, the surface structure and the surface inclination of the detected object.
    Through adjusting the potentiometer or mechanical adjustment knob in the photoelectric sensor, to improve the receiving sensitivity for reflected light. In the case of a fixed detection distance at the scene, if there is a strong reflected light background. In order to avoid photoelectric switch malfunction, it's better to use a background suppression diffuse photoelectric sensor. Or directly keep away from the background, remove the background, paint the background to be matt black, make the background to be rough or gray and other methods to eliminate bad effect.

    Easy to connect and use
    It works together with the 4 digit up/down digital counter. Easy to connect and use.

    Sensitive and Stable
    After test, I can see the diffuse reflective photoelectric sensors are very sensitive. The transparent objects can be sensed quickly. I use the photoelectric sensors for the cloth rectifying controller. And now the control system is very stable.

    Can the output of a digital counter be connected to another machine?
    I watched a YouTube video from ATO using a photoelectric sensor and digital counter. I would like to purchase both the sensor and digital counter. Also, I want to connect the output of the digital counter to another machine (EFD) using a 8-pin I/O port (5-24VDC), is this possible?

    ATO Responded
    Dear Joshua,

    1. What type of sensor and digital counter do you want to purchase?
    2. What function do you want to achieve by connecting the output of the digital counter to another machine (EFD), and what input signals does your machine EFD support? Can you provide us a manual?
