Why Choose the Carlo Gavazzi PMT20RGM Through-Beam Photoelectric Sensor?
The Carlo Gavazzi PMT20RGM is an industrial through-beam photoelectric receiver with muting functionality, designed for reliable long-range object detection in automation and machine-control applications. Part of the Carlo Gavazzi PMT series, it is intended for use with a separate through-beam transmitter and provides dependable detection across large machinery, conveyor systems and material handling installations.
The PMT20RGM uses the through-beam sensing principle, with a transmitter and receiver positioned on opposite sides of the monitored area. The receiver continuously monitors the modulated optical beam from the corresponding transmitter and changes its output state when an object interrupts the beam. With an operating distance of up to 20 m, this arrangement provides reliable detection without depending on the colour, surface finish or reflectivity of the target.
The PMT20RGM provides an SPDT change-over relay output for flexible connection to industrial control circuits and incorporates a muting input for temporarily inhibiting the sensor output when required by the application. Its robust rectangular housing, PG13.5 cable entry and industrial terminal connection make it well suited to permanent installations in production, logistics and materials-handling equipment.

Long-Range Through-Beam Detection with Muting Control
Through-beam photoelectric systems use separate transmitting and receiving devices installed on opposite sides of the detection area. The Carlo Gavazzi PMT20RGM acts as the receiver, monitoring the optical beam generated by the corresponding transmitter. When an object interrupts the beam, the receiver changes the state of its SPDT relay output, allowing the connected machine controller or control circuit to respond.
The integrated muting function provides additional control flexibility by allowing the sensing response to be temporarily inhibited under defined process conditions. This can be useful in automated material handling and machine processes where known objects must pass through the sensing field without initiating the normal control response, while the 20 m through-beam range supports reliable detection across large equipment and production areas.
Typical Applications
- Long-range conveyor object detection.
- Material handling and logistics systems.
- Packaging and processing machinery.
- Automated production lines.
- Product presence and absence monitoring.
- Machine sequencing and process control.
- Applications requiring temporary sensor muting.
- Industrial relay-based automation systems.
