OPTEX UK — Market presence

OPTEX UK supplies a comprehensive range of automatic door sensors for use with compatible operator platforms. The brand is particularly valued for its stable detection logic, installer-friendly adjustment, and long-term availability, making OPTEX sensors a common choice for both new installations and retrofit upgrades.

Core sensor platforms & model families

OPTEX automatic door sensors are structured around clearly defined model families familiar to engineers:

Activation sensors

• OA-203C — a legacy active infrared activation sensor, now discontinued by OPTEX; referenced here for identification of existing equipment

• OM106 — compact microwave activation sensor for internal doors and restricted mounting positions

• Designed to provide stable opening signals while minimising unwanted activation

Advanced activation & safety sensors

• OA-AXIS T — advanced active infrared sensor offering precise presence detection with adjustable detection zones, commonly used for safety coverage on automatic sliding doors

• Suitable for threshold protection and enhanced safety compliance

Safety & presence detection sensors

• OA-EDGE — an active infrared presence sensor mounted on automatic swing doors

Combined activation & safety solutions

• Hybrid OPTEX sensors combining activation and safety functions in a single housing

• Model-specific detection fields and mounting arrangements for the intended door application

Typical applications

OPTEX sensors are commonly installed on:

• Automatic sliding doors

• Automatic swing doors

• Telescopic and curved entrances

• Internal and external commercial doorways

• Healthcare and high-traffic public buildings

Why OPTEX sensors are widely specified

• Proven Japanese engineering and sensor expertise

• Accurate, stable detection in changing environmental conditions

• Recognisable and consistent model platforms (OA-AXIS T, OA-EDGE)

• Compatibility determined by the sensor version and operator interface

• Long product life supporting maintenance-led ownership models

The OPTEX sensors listed in this collection include OA-EDGE for on-door swing applications, OA-AXIS T for monitored sliding-door applications, OA-PRESENCE TN, Mirage and OM106 activation equipment. Start with the required function—activation, presence detection or on-door coverage—then check mounting height, position, supply and monitoring connections against the chosen product documentation. A sensor with a similar housing is not necessarily a direct replacement. Contact us with the existing model reference if you need help identifying an alternative.
