3-50cm E18-D50NK Photoelectric sensor IR Infrared Obstacle
Avoidance Sensor
Description:
Tunable 3-50cm; E18-D50NK; infrared obstacle avoidance sensor;
close switch; smart car
This is a set of transmitter and receiver in one of the
photoelectric sensor. Detection distance can be adjusted according
to the requirements. The sensor has a detection distance by visible
light interference small, cheap, easy to assemble, easy to use, and
other characteristics, can be widely used in robot obstacle
avoidance, pipeline piecework and many other automation products.
Photoelectric sensor (photoelectric switch) NPN normally open
