IMX-A842 Infrared Photoelectric Multiplexer

Manufacturer: Pantron Instruments, GmbH
Category: Infrared Photoelectric Multiplexers

8-channel multiplex amplifier with manual gain setting. The PANTRON multiplex process guarantees a strict channel separation, even if the eight light barriers are mounted very closely. Four level settings allow the multiplexer to be adjusted to overcome distance and other conditions.

The Master/Slave operation makes it possible to synchronize several multiplex amplifiers. This feature allows the light barrier to utilize more than eight beams.
