Why Choose the Carlo Gavazzi PAM02AN3APO Photoelectric Amplifier?
The Carlo Gavazzi PAM02AN3APO is a 2-channel photoelectric amplifier designed for use with compatible Carlo Gavazzi MOFTR through-beam photoelectric sensor sets. Its modular, microprocessor-controlled architecture provides centralised signal processing for industrial object detection applications while allowing two independent sensing channels to be managed from a single DIN-rail-mounted amplifier.
Each channel provides an independent PNP normally open (make-switching) transistor output. When used with compatible MOFTR transmitter and receiver heads, the PAM system supports through-beam detection over distances of up to 50 m, with adjustable sensitivity, alignment assistance and self-diagnostic functions helping engineers commission and maintain the sensing system.
The PAM02AN3APO operates from 18–33 V DC and provides a continuous resistive load capability of 20 mA per output. Its 48 × 96 × 60 mm closed housing is designed for DIN-rail mounting and uses quick-disconnect terminals, while synchronised and multiplexed channel operation improves ambient-light immunity and helps prevent optical cross-talk between sensing channels.
Key Advantages
- Two independent sensing channels allow two compatible through-beam sensor sets to operate from one amplifier.

Two-Channel Through-Beam Detection for Industrial Machinery
The PAM02AN3APO provides the amplification and control functions for compatible remote through-beam photoelectric sensor heads. A through-beam system positions a transmitter and receiver opposite one another to establish an optical path across the monitored area. When an object interrupts that beam, the amplifier processes the receiver signal and switches the corresponding PNP normally open output.
The PAM architecture synchronises the sensing system for improved immunity to ambient light and multiplexes the channels to minimise cross-talk between adjacent photoelectric sensor sets. Combined with adjustable sensitivity, self-diagnostics and alignment assistance, the PAM02AN3APO provides a flexible solution for applications requiring remote sensing heads, long detection distances or centralised control-panel installation.
