Optex BC-3 Back Cover Pir Motion Detector

Product Description

The OPTEX BC-3 is a replacement back cover designed for OPTEX AX-series passive infrared (PIR) motion detectors. It serves as the rear housing component that encloses and protects the detector's internal electronics. This cover is a direct OEM-style replacement part, sold individually, and is typically installed by security technicians or electricians during repair or replacement of a damaged housing on an existing PIR unit. The BC-3 restores the physical integrity of the detector enclosure, helping maintain proper environmental sealing and mounting stability.

This back cover is intended for use with OPTEX AX-series PIR motion detectors in commercial and residential security applications. Typical install scenarios include field repair of a cracked or broken housing, replacement after physical damage during installation, or refurbishment of existing detector units. It fits detectors mounted on walls or ceilings in standard indoor security system layouts.
