Feature: 1. 6m Sensing Distance: The photoelectric obstacle avoidance sensor has a great 6m sensing distance, little interference from visible light, and the detection distance can be adjusted according to requirements. 2. Transmitting Receiving Available: Our sensor is an diffuse reflection photoelectric sensor that combines transmitting and receiving in one. 3. Working Process: Diffuse reflection switch to the target uninterrupted emission beam receiver to receive the light energy converted to current transmission to the back of the detection line, it can filter out the effective signal and application of the signal. 4. Wide Application: Diffuse reflection photoelectric sensor can be widely used in robot obstacle avoidance, assembly line piece counting and many other automation products. 5. ABS Material and Easy to Use: The photoelectric obstacle avoidance sensor is made of ABS material, superb craftsmanship, easy to assemble, easy to use, can also be used in the production line goods automatic counting equipment, multifunctional reminder. Specification: Item Type: Photoelectric Sensor Model: E139 R6JC Material: ABS Sensing Range: Approx. 6m / 20ft Response Time: <2m/20ms Pointing Angle: 3°, -10°, -20° Operating Ambient Temperature: -25 - +55℃ Protection Level: IP54 Photoelectric Switch Working Principle Photoelectric switch is also known as photoelectric sensor, the sensor is divided into diffuse reflection type, feedback reflection type, opposite type sensor, and PLC programmable controller, microcontroller, non gate circuit electronic counter, solid state relay, small relay and other products supporting the use. The transmitting type is aimed at the target uninterrupted emission beam receiver to convert the received light energy into current transmission to the detection line behind, it can filter out the effective signal and apply the signal. This photoelectric switch of ours is a diffuse reflective type.. Package List: 1 x Photoelectric Diffuse Reflection Sensor
