pam02an3apc – photo amp 2ch pnp nc
Carlo Gavazzi PAM02AN3APC is a two-channel DIN-rail photoelectric amplifier for compatible through-beam sensors with 18–33 V DC supply, independent PNP normally closed outputs, adjustable sensitivity, diagnostics and alignment assistance.
Why Choose the Carlo Gavazzi PAM02AN3APC Photoelectric Amplifier?
The Carlo Gavazzi PAM02AN3APC is a 2-channel photoelectric amplifier designed for use with Carlo Gavazzi MOFTR through-beam photoelectric sensor sets in industrial automation and machine control applications. The microprocessor-controlled PAM system provides centralised amplification, output processing and diagnostic functions for remote photoelectric sensing heads.
The PAM02AN3APC supports two photoelectric sensing channels and provides independent PNP normally closed (break-switching) transistor outputs. When paired with compatible MOFTR through-beam sensors, the system can support sensing distances of up to 50 m, while adjustable sensitivity and alignment assistance help simplify commissioning and optimise detection reliability.
Operating from 18–33 V DC, the amplifier is housed in a compact 48 × 96 × 60 mm DIN-rail-mountable enclosure with quick-disconnect terminals. Self-diagnostic functions, multiplexed channels for reduced optical cross-talk and synchronised operation for high ambient-light immunity make it a capable solution for demanding industrial sensing systems.

Two-Channel Through-Beam Detection for Industrial Machinery
The PAM02AN3APC acts as the control and amplification unit for compatible remote through-beam photoelectric sensor heads. A through-beam system positions a transmitter and receiver opposite one another, creating an optical path across the monitored area. When a target interrupts the beam, the amplifier processes the change and switches the corresponding PNP normally closed output.
The amplifier's microprocessor-controlled architecture provides independent processing for two sensing channels while synchronisation and multiplexing improve immunity to ambient light and minimise cross-talk. Adjustable sensitivity, diagnostic functions and alignment assistance make the PAM02AN3APC particularly useful where remote sensor heads, long detection distances or centralised control-panel installation are required.
Typical Applications
- Long-range through-beam object detection.
- Conveyor product and package monitoring.
- Packaging and processing machinery.
- Material handling and logistics systems.
- Production-line presence detection.
- Machine entry and exit monitoring.
- Industrial counting and positioning systems.
- Centralised photoelectric sensing in automation control panels.
