Why Choose the Carlo Gavazzi MPF1-912RSI Photoelectric Amplifier?
The Carlo Gavazzi MPF1-912RSI is a single-channel photoelectric amplifier from the MPF series, designed for use with Carlo Gavazzi MPFT transmitters and MPFR receivers in through-beam photoelectric sensing systems. It provides the power, signal processing and relay switching required to create a complete industrial detection system using remotely mounted photoelectric sensor heads.
Designed for a 12–24 V AC/DC supply, the MPF1-912RSI incorporates one multiplexed sensing channel and an SPST relay output. Its positive-security operating principle is designed so that loss of supply, a short circuit or a broken sensor cable causes the relay to switch to its off state, supporting dependable fault detection in industrial doors, gates and automation equipment.
The MPF1-912RSI also features an inverted test input (break function). The test facility disables the connected emitter so that operation of the photoelectric sensing system can be evaluated. With a compact 70 × 57 × 86 mm amplifier housing, the unit provides a practical control interface for Carlo Gavazzi MPF separate-head photoelectric systems.

Reliable Photoelectric Control with Functional Testing
The Carlo Gavazzi MPF system separates the photoelectric transmitter and receiver heads from the amplifier electronics. This architecture allows compact sensor heads to be positioned at the detection point while the MPF1-912RSI handles power, signal processing and relay switching from a convenient control location.
A key feature of the MPF1-912RSI is its inverted test input. The test circuit can disable the connected emitter, allowing the system to verify that interruption of the optical signal produces the expected response. The amplifier's positive-security design also ensures that conditions such as loss of power, sensor-cable breakage or short circuit cause the output relay to move to its off state.
Typical Applications
- Automatic industrial doors and gates.
- Through-beam photoelectric detection systems.
- Industrial conveyor monitoring.
- Packaging and production machinery.
- Material handling equipment.
- Presence and passage detection.
- Automation systems requiring remotely mounted photoelectric sensor heads.
