mpf3-912rsai – photo amp 3 ch 12-24vac/dc test break

Why Choose the Carlo Gavazzi MPF3-912RSAI Photoelectric Amplifier?

The Carlo Gavazzi MPF3-912RSAI is a three-channel photoelectric amplifier designed for Carlo Gavazzi MPF through-beam sensing systems used in industrial doors, gates and automation equipment. It provides centralised power, signal processing and relay switching for up to three compatible transmitter and receiver sensor pairs.

Operating from a flexible 12–24 V AC/DC supply, the MPF3-912RSAI features three multiplexed sensing channels that help prevent optical cross-talk between adjacent photoelectric sensor pairs. This model also incorporates a break test input, enabling an external control system to disable the emitters and verify correct operation of the sensing system.

The amplifier is designed for through-beam sensing over a nominal distance of 15 m with compatible MPF transmitter and receiver heads. An SPST relay output, LED indication, DIN-rail housing and IP40 protection provide straightforward integration into protected industrial control panels.

Reliable Multi-Channel Photoelectric Control for Industrial Machinery

The MPF3-912RSAI provides the central electronic interface for up to three separate through-beam photoelectric sensing pairs. Each transmitter directs an infrared beam towards its corresponding receiver, while the amplifier sequentially multiplexes the channels to minimise interference between neighbouring sensor sets. Objects or obstructions interrupting a beam can then be detected through the amplifier's relay switching system.

The integrated test input is designed to disable the connected emitters so that the control system can evaluate sensor functionality. Combined with positive-security relay operation, this makes the MPF3-912RSAI particularly suitable for industrial doors and gates where dependable obstruction detection and system monitoring are important.

Typical Applications

• Industrial and automatic door sensing systems.
• Gate and access-control installations.
• Multi-beam obstruction detection.
• Conveyor product and object detection.
• Material handling and sorting systems.
• Packaging and processing machinery.
• Industrial automation requiring up to three through-beam detection channels.
