Allen-Bradley 42CB-U1LPA-M4

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.
