Why Choose the Carlo Gavazzi MPF1-912RSAI Photoelectric Amplifier?
The Carlo Gavazzi MPF1-912RSAI is a single-channel photoelectric amplifier designed for use with compatible Carlo Gavazzi MPFT transmitters and MPFR receivers in through-beam detection systems. Developed particularly for industrial doors, gates and automation equipment, it combines sensor signal processing, adjustable sensitivity and relay switching in a compact control unit.
Part of the Carlo Gavazzi MPF series, the MPF1-912RSAI operates from a versatile 12–24 V AC/DC supply and provides an SPST relay output. This RSAI version incorporates a break-contact test input, allowing the connected photoelectric system to be functionally tested by disabling the transmitter and verifying the resulting detection response.
The amplifier supports one photoelectric sensing channel and is designed for Carlo Gavazzi MPF separate-head through-beam systems, which can provide a nominal sensing range of 15 m with the appropriate transmitter and receiver. Its rectangular 86 × 50 × 57 mm polycarbonate housing and terminal connections make it suitable for integration into industrial control systems and automatic door equipment.

Reliable Through-Beam Detection with Functional Testing
The MPF photoelectric system uses separate transmitter and receiver heads positioned across the area to be monitored. Modulated infrared light passes between the two sensing heads, while the MPF1-912RSAI evaluates the receiver signal and operates its relay when the beam condition changes. This arrangement provides reliable presence and obstruction detection without requiring the amplifier itself to be mounted at the sensing point.
The integrated break-contact test input allows the transmitter to be disabled so that operation of the sensing system can be checked. Combined with adjustable sensitivity and relay output switching, this makes the MPF1-912RSAI particularly suitable for automatic doors, industrial gates and machinery where dependable photoelectric detection and functional verification are important.
