pam04an3apo – photo amp 4ch std pnp no
Carlo Gavazzi PAM04AN3APO is a four-channel photoelectric sensor amplifier with PNP normally open outputs, an 18–33 V DC supply, adjustable sensitivity and DIN-rail mounting for industrial through-beam sensing systems.
Why Choose the Carlo Gavazzi PAM04AN3APO Photoelectric Sensor Amplifier?
The Carlo Gavazzi PAM04AN3APO is a versatile four-channel photoelectric sensor amplifier designed for use with compatible MOF through-beam photoelectric sensor sets in industrial automation systems. As part of the modular Carlo Gavazzi PAM series, it combines four sensing channels with independent PNP normally open transistor outputs for reliable object detection and machine control.
The PAM04AN3APO incorporates adjustable sensitivity, diagnostic functions and an alignment aid to simplify sensor commissioning and ongoing operation. Its multiplexed sensing architecture helps prevent crosstalk between channels, while modulated and synchronised light operation provides strong immunity to ambient light interference.
Operating from an 18–33 V DC supply, the PAM04AN3APO provides a PNP normally open (NO) output for each channel. The amplifier is designed for DIN-rail mounting with terminal connections and provides a practical centralised solution for four through-beam sensing points in conveyors, packaging machinery and automated production equipment.

Reliable Multi-Channel Photoelectric Sensor Control
Photoelectric amplifier systems separate the sensing heads from the central signal-processing electronics, making them particularly useful where multiple detection points must be integrated into automated machinery. The PAM04AN3APO processes four through-beam sensing channels and supplies individual transistor outputs that can interface with PLCs and other industrial control equipment.
The PAM system uses modulated and synchronised sensing signals together with multiplexed channels to improve ambient-light immunity and minimise interference between sensor pairs. Built-in diagnostics, sensitivity adjustment and alignment assistance further support reliable commissioning and dependable operation in demanding industrial applications.
Typical Applications
- Conveyor object detection and product counting.
- Packaging and filling machinery.
- Material handling and sorting systems.
- Automated assembly and production equipment.
- Presence and position monitoring.
- Multi-point through-beam detection systems.
- Industrial machine and process automation.
