Optex LX-402 Outdoor Pir Motion Sensor

Product Description

The OPTEX LX-402 is a passive infrared (PIR) motion sensor designed for outdoor detection applications. It covers a 40-foot by 50-foot detection zone, making it suited for perimeter security, access control, and outdoor lighting control installations. The LX-402 operates on PIR technology, sensing changes in infrared energy caused by moving persons or objects within the detection field. Licensed security technicians and low-voltage electricians typically install this unit as part of a broader alarm or automation system.

The LX-402 is intended for outdoor environments where reliable motion detection across a wide coverage area is required. Typical applications include residential and light commercial perimeter monitoring, outdoor security lighting activation, and entry-point detection. Its detection pattern spans a 40-foot width and 50-foot depth, providing broad coverage for driveways, yards, loading areas, and building exteriors.

Key Features

• Passive infrared detection technology for reliable outdoor motion sensing
• 40-foot by 50-foot detection coverage zone
• Designed for outdoor installation environments
• Single-unit packaging for individual zone replacement or new installation

Compatibility

Designed as an OEM-style outdoor PIR motion sensor suitable for integration into standard security, access control, and outdoor lighting control systems that accept PIR detector inputs.

Installation Notes

Installation is typically performed by a licensed low-voltage technician or security systems installer in accordance with local codes and NEC guidelines. Power down or de-energize the control panel circuit before wiring the detector. Mount the sensor at the manufacturer-recommended height to achieve the stated detection coverage, and avoid positioning the unit where direct sunlight, HVAC exhaust, or heat sources may cause false triggers. Confirm weatherproofing at all conduit entries to maintain outdoor rating integrity.
