10NK Infrared Photoelectric Switch Obstacle Sensor

The 10NK is a compact infrared photoelectric switch that integrates both an infrared transmitter and a receiver in a single module. It is designed to detect objects within a fixed distance of 10 centimeters, which is not adjustable. The sensor operates on a 5V DC power supply and consumes less than 25mA of current. Its output is an NPN normally-open (NO) configuration capable of sinking up to 100mA, allowing it to directly drive relays or other low-power loads.

Performance and Usage:
