The PAC 20110 OneProx GS3 LF Mullion Reader is the kind of access control hardware that earns its place on a door frame and stays there. Compact enough to fit neatly onto mullion installations, it's built to perform consistently across demanding environments — whether that means an exposed entrance, a high-traffic internal door, or anywhere in between. IP65-rated and fully weather resistant, it handles indoor and outdoor deployment without complaint.

Compatibility is where this reader does its quiet, reliable work. It supports PAC and KeyPAC credentials natively, and connects to third-party systems via Wiegand — so it fits into most existing access control setups without forcing a wider overhaul. The 85mm reading range keeps pedestrian flow moving without requiring users to press their card against the reader.

For facilities managers or security installers who need a dependable, well-specified LF reader that doesn't demand special treatment from its environment, the GS3 LF is a straightforward, practical choice.
