Why Choose the Carlo Gavazzi MPF3-912RS Photoelectric Amplifier?
The Carlo Gavazzi MPF3-912RS is a three-channel through-beam photoelectric amplifier designed for industrial doors, gates and automation systems requiring multiple photoelectric detection points. Part of the Carlo Gavazzi MPF series, it provides signal processing and relay switching for compatible separate transmitter and receiver heads.
The MPF3-912RS operates from a flexible 12–24 V AC/DC supply and supports three sensing channels, allowing several through-beam positions to be monitored from a single amplifier. It features SPST relay outputs, a dedicated test input and light/dark switching functionality for straightforward integration into industrial control circuits.
Designed for DIN-rail mounting, the amplifier uses a compact rectangular plastic housing measuring approximately 70 × 57 × 86 mm. Its IP40 protection rating and infrared photoelectric operating principle make it well suited to enclosed control panels used with industrial doors, gates, material handling systems and automated machinery.

Reliable Three-Channel Through-Beam Detection
The MPF3-912RS works with separate through-beam photoelectric transmitters and receivers positioned across the areas being monitored. The amplifier evaluates the infrared sensing signals from up to three channels and operates its relay contacts according to the detected beam conditions.
This three-channel architecture is particularly useful for industrial doors and gates where several beam heights may be required for obstruction or presence detection. DIN-rail mounting, low-voltage AC/DC operation and the integrated test input also make the MPF3-912RS straightforward to incorporate into industrial control panels and automated machinery.
Typical Applications
- Industrial automatic doors and gates.
- Multi-beam doorway presence and obstruction detection.
- Conveyor and material handling systems.
- Packaging and production machinery.
- Warehouse and logistics automation.
- Machine openings and access-point monitoring.
- Industrial automation and machine-building systems.
