PHOTOSWITCH Bulletin 42CB High Speed 18mm Cylindrical
IMPORTANT: SAVE THESE INSTRUCTIONS FOR FUTURE USE.
Description
Bulletin 42CB are high speed 18mm cylindrical sensors
available in several sensing modes, with various detection
ranges.
The Fixed Focus Diffuse uses a visible red LED, all the other
sensing modes use an infrared LED.
These sensors are available with 10–30V DC, either PNP or
NPN output and selectable light/dark operate mode on each
sensor.
The sensitivity adjustment potentiometer and two LED
indicators are mounted in the rear. The LED’s show the
output is energized (yellow) and power is on (green).
Fast response time and the high switching frequency of all the
Bulletin CB sensors (1kHz) allows for accurate detection of
objects moving at high speed.
The right angle orientation of this bulletin reduces the overall
dimension of the sensor, and reduces the chance of
accidental tearing.
