The HID 5375AGN04 is a MAXIPROX Wiegand proximity reader designed for access control integrations requiring reliable credential reading and communication over Wiegand protocol. This gray terminal reader delivers straightforward proximity card detection suitable for standard door access applications across commercial, institutional, and light industrial environments.
The 5375AGN04 functions as a dedicated proximity reader terminal, communicating credential data through industry-standard Wiegand output. The terminal format positions the reader for mounting at door frames, walls, or access points where direct integration with access control panels or controllers is required. Lead-free construction meets environmental compliance requirements for modern security deployments.
The HID 5375AGN04 interfaces through Wiegand output, making it compatible with access control panels, controllers, and systems that accept standard 26-bit or 34-bit Wiegand data streams. This protocol support enables integrators to deploy the reader across mixed-technology environments without requiring protocol conversion or gateway hardware.
As part of HID's MAXIPROX reader family, the 5375AGN04 works with HID proximity credentials and systems configured for Wiegand-based authentication. Integration verification with your specific access control platform is recommended to confirm data format compatibility and reader initialization procedures.
Terminal readers require direct electrical connection and Wiegand data lines to the access control system. Door mounting and conduit routing should follow local electrical and security installation standards. The gray color blends with standard institutional finishes while maintaining visibility for user credential presentation. Lead-free compliance is essential for facilities with environmental compliance mandates or international equipment sourcing requirements.
The model 5375AGN04 is catalogued across major security distributor networks and represents a core MAXIPROX reader option for standard access control deployments where Wiegand protocol support is the integration requirement.

The HID 5375AGN04 is a workhorse proximity reader that fills a specific role in access control architecture: direct Wiegand output to legacy and modern panels. During integrations where your access control system has native Wiegand inputs, this reader eliminates the need for protocol converters or middleware, reducing points of failure and simplifying commissioning.

Deployment Considerations:
For integrators managing mixed-age access control systems or requiring straightforward Wiegand readers without cloud dependency or complex initialization, the 5375AGN04 is a reliable, catalog-standard choice. Pair it with HID MAXIPROX credentials and ensure your control panel has Wiegand capability at the reader position.
