mpf3-912rsa – photo amp 3 ch 12-24vac/dc test make
Carlo Gavazzi MPF3-912RSA is a three-channel 12–24 V AC/DC through-beam photoelectric amplifier with adjustable sensitivity, relay outputs, a make-contact test input, 15 m nominal sensing capability with compatible MPF heads and IP40 protection.
Why Choose the Carlo Gavazzi MPF3-912RSA Photoelectric Amplifier?
The Carlo Gavazzi MPF3-912RSA 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 evaluation, sensitivity adjustment and relay switching for compatible separate transmitter and receiver heads.
The MPF3-912RSA operates from a versatile 12–24 V AC/DC ±15% supply and supports three multiplexed sensing channels, helping prevent cross-talk between adjacent photoelectric beams. This RSA version adds distance / sensitivity adjustment together with a make-contact test input, allowing the connected emitters to be functionally tested as part of the wider control system.
When used with compatible MPF transmitter and receiver heads, the amplifier supports a nominal sensing distance of up to 15 m. Its compact 70 × 57 × 86 mm housing, IP40 protection, 10 Hz operating frequency and DIN-rail format make it well suited to enclosed industrial control panels and automatic door systems.

Reliable Three-Channel Through-Beam Detection
The MPF3-912RSA works with separate photoelectric transmitters and receivers positioned across the areas being monitored. Its three multiplexed channels sequentially evaluate the connected sensing pairs, helping prevent adjacent optical beams from interfering with one another while allowing several detection points to be managed from a single amplifier.
The adjustable sensitivity feature allows the sensing system to be tuned to the application, while the make-contact test input can disable the emitters for functional evaluation. This combination makes the MPF3-912RSA particularly suitable for automatic doors, industrial gates and machinery requiring dependable multi-beam presence or obstruction detection.
Typical Applications
- Industrial automatic doors and gates.
- Three-beam doorway presence and obstruction detection.
- Conveyor and material handling systems.
- Packaging and production machinery.
- Machine openings and access-point monitoring.
- Warehouse and logistics automation.
- Industrial control and machine-building systems.
