IMX-A831 Infrared Photoelectric Multiplexer

Manufacturer: Pantron Instruments, GmbH
Category: Infrared Photoelectric Multiplexers

8-channel multiplex amplifier with automatic gain setting. The PANTRON multiplex process guarantees a strict channel separation, even if the eight light barriers are mounted very closely. Two programmable 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.
