Why Choose the Carlo Gavazzi MPF3-912RSI Photoelectric Amplifier?
The Carlo Gavazzi MPF3-912RSI is a three-channel photoelectric amplifier designed for Carlo Gavazzi MPF through-beam sensing systems. It provides centralised signal processing and switching for compatible MPFT transmitter and MPFR receiver sensing heads, making it particularly suitable for industrial doors, gates and automated machinery requiring multiple detection points.
Operating from a flexible 12–24 V AC/DC supply, the MPF3-912RSI supports three photoelectric sensing channels from a single amplifier. This model incorporates a test break function and provides an SPST relay output, allowing straightforward integration with industrial door, gate and machine control circuits.
The MPF system provides a nominal through-beam sensing range of 15 m, with installation-dependent operating distances of approximately 6–20 m. The MPF3-912RSI uses a compact rectangular polycarbonate housing with terminal connections and IP40 protection, making it suitable for installation within protected industrial control equipment.

Reliable Multi-Channel Photoelectric Control for Industrial Automation
The MPF3-912RSI provides the central interface between up to three compatible MPFT transmitter and MPFR receiver sensing pairs and the wider control system. Each transmitter projects a beam towards its corresponding receiver, allowing objects or obstructions to be detected when the optical path is interrupted. The amplifier processes these sensing signals and provides its relay output to the connected control equipment.
Using one amplifier for three sensing channels provides an efficient solution for installations requiring multiple detection points. The separate photoelectric heads can be positioned where sensing is required while the MPF3-912RSI remains protected with the electrical control equipment, making the system particularly useful for industrial doors, gates and automated machinery.
Typical Applications
- Industrial and automatic door sensing.
- Gate and access-control systems.
- Multi-beam obstruction detection.
- Conveyor product and object detection.
- Packaging and processing machinery.
- Material handling and sorting equipment.
- Industrial automation requiring up to three through-beam detection channels.
