Product Introduction

The air shower infrared sensor provides a non-contact presence signal to the sequence controller when a person or material load enters the sensing zone. A dark optical window shields the emitter and receiver components, while the status LED supports alignment and service checks. Side mounting ears hold the sensing face in a repeatable position inside the chamber. Replacement compatibility depends on sensing principle, supply voltage, output logic, connector arrangement and required detection distance.

Key Features

Non-contact detection avoids switches that require physical actuation.

A tinted optical window protects the sensing elements from routine chamber cleaning.

The visible indicator provides immediate confirmation of detection status.

Twin metal mounting ears support stable alignment on the air-shower panel.

Customer Product Concerns

Reliable cycle triggering requires a sensor that matches the controller input and remains correctly aimed in the chamber.

A narrow or misaligned detection zone fails to register chamber entry.Twin mounting ears provide repeatable positioning toward the intended sensing area.

An incompatible output signal cannot trigger the existing controller.Output logic and supply configuration are selected for the installed control input.

Contamination on exposed optics causes unstable sensing.The smooth tinted window presents a protected, wipe-clean optical face.

Technicians cannot quickly confirm whether the sensor is switching.A dedicated green indicator displays local detection status during testing.

Typical Applications
