Photoelectric Sensor: It is a set of transmitting and receiving in one photoelectric sensor. Output current DC / SCR / Relay Control output: 100mA / 5V power supply. Direct current 003c25mA. Professional Tools: The photoelectric switch uses the blocking or reflection of the detected object on the beam, to detect the existence of the object. This photoelectric switch sensor features high precision, fast response, high reliability and strong anti-interference ability. Widely Used: The photoelectric switch has a wide range of applications, can be widely used in robot obstacle avoidance, pipeline line part and many other automation products, the detection objects are not limited to metal and all the reflective light) objects can be detected. Design: The photoelectric switch converts the input current into a light signal on the transmitter and the receiver detects the target object according to the intensity or presence of the received light. This photoelectric switch stays open and closes when it detects the object in the detection range. Specifications: Model: E18-D80NK Electrical Characteristics: U: 5VDC I: 100mA Sn: 3-80cm Size: Diameter: 18mm / 0.71in Sensor Length: 45mm / 1.77in Lead Length: 45.5cm / 17.9in Weight: 28g Package Included: 1 x Infrared Sensor Switch Note: Other items are not included, the color is based on the first picture, and other pictures only show the effect Due to the differences between different monitors, the picture may not reflect the actual color of the item.
