The PAC 20111 OneProx GS3 LF Standard Reader is a low-frequency proximity reader built for access control installations where reliability is non-negotiable. It delivers the same core functionality as a mullion reader but in a larger form factor — the kind of choice that makes sense when you want a more substantial presence at a door or entry point without sacrificing performance.

Rated IP65, it handles indoor and outdoor environments without complaint. Rain, dust, temperature swings — it's designed for demanding conditions rather than controlled ones. With an 85mm reading range and compatibility with PAC, KeyPAC, and third-party credentials via Wiegand, it fits neatly into existing systems without forcing a full infrastructure rethink.

For installers and security managers sourcing readers that work across mixed-credential environments, the GS3 LF standard offers a straightforward, dependable option that earns its place on the wall.
