irphs20 – heavy duty photoswitch 20m

Why Choose the Carlo Gavazzi IRPHS20 Heavy-Duty Infrared Photoswitch?

The Carlo Gavazzi IRPHS20 is a heavy-duty infrared through-beam photoelectric switch designed for reliable presence and obstruction detection in demanding industrial, commercial and automatic-door applications. The system uses a separate infrared transmitter and receiver to create a dependable optical barrier across the monitored area.

Designed for a maximum 20 m indoor sensing distance, the IRPHS20 uses a 950 nm infrared beam and provides both normally-open (NO) and normally-closed (NC) relay outputs. Horizontal optical adjustment through 180° helps simplify transmitter-to-receiver alignment, making the sensor particularly suitable for doors, gates, entrances and access-control installations.

The transmitter and receiver can operate from 12/24 V AC/DC, selected according to the supply configuration, while the relay contacts are rated at 1 A at 24 V AC for resistive loads. Rugged IP66 enclosures, a -20 to +60 °C operating temperature range and wall-mounting design make the IRPHS20 a durable sensing solution for challenging indoor and outdoor installations.

Reliable Heavy-Duty Infrared Barrier Detection

Through-beam photoelectric sensors use a dedicated transmitter and receiver positioned opposite one another. The transmitter projects an infrared beam towards the receiver, creating an optical barrier across the monitored area. When an object interrupts this beam, the receiver changes the relay output state so that compatible door-control, automation or security equipment can respond.

The IRPHS20 combines a long 20 m indoor range with rugged IP66 construction and adjustable optics, making it particularly suitable for large door openings and challenging access-control installations. Its NO and NC relay outputs provide flexible interfacing with compatible control equipment, while the alignment indication assists commissioning and maintenance.
