HID 5365EGP00 MiniProx Proximity Reader Grey

We've deployed the HID 5365EGP00 across dozens of retrofit and new-build access control projects, and it remains one of the most reliable solutions for sites already committed to 125 kHz proximity infrastructure. The mullion mount is the defining advantage here—most integrators install this reader on projects where space is tight, budgets don't support credential migration, or existing card stocks (tens of thousands of cards) would be too costly to replace. We've had installations run seven+ years without reader failure, and the tamper-switch integration has caught genuine bypass attempts on a handful of loading-dock deployments. The reader is not sexy—it doesn't do OSDP, doesn't support mobile credentials, doesn't offer audit logging at the reader level—but that's not what it's designed to do. It's a straightforward, proven converter between unencrypted proximity cards and Wiegand protocol for panels that support that format. Compared to encrypted 13.56 MHz alternatives, the 5365EGP00 wins on cost-of-ownership (no credential replacement), installation speed (drops into a mullion in under two hours), and interoperability with older access control hardware (1990s-era panels that only understand Wiegand).

Technical Highlights:

• SIA 26-bit Wiegand Protocol: Native Wiegand output—no conversion modules, no serial bridging, no firmware updates. Pair it with any panel that has a Wiegand input, and enrollment works immediately. On a 50-reader campus, that's a significant reduction in configuration overhead versus heterogeneous reader types.
• Mullion-Mount Design: 6.0" × 1.7" footprint. We've mounted this reader on aluminum mullions as thin as 1.25" with proper spacers, and on glass door frames using the optional glass kit. Retrofit labor drops measurably when you don't need custom fabrication.
• 125 kHz Credential Compatibility: Reads passive proximity cards and fobs with zero modifications. If your facility has 50,000 active cards in circulation, you don't replace them—you install these readers and integrate them into your existing access panel. That's capex you don't spend.
• Tamper-Switch Output: Built-in detection alerts the access control system if the reader is physically compromised. We've used this on unsecured loading docks and back-of-house areas where credential tampering is a historical risk. Minimal additional wiring.
• 5VDC Low-Power Draw: Sub-200mA operation. Simplifies power sourcing on retrofit projects where you're pigtailing off an existing panel supply or door controller. No need for separate 12VDC supplies or additional conduit runs.

Deployment Considerations:

• Credential Format Verification: Confirm your access control panel explicitly supports SIA 26-bit Wiegand input before ordering. Older legacy systems may default to other Wiegand formats (34-bit, proprietary). A single datasheet review saves a site visit if the format is incompatible.
• Mullion Geometry and Material: Measure mullion thickness, material (aluminum vs. stainless), and any existing hardware before specifying the mounting bracket. Ferrous metals can reduce read range by 20-30%—position the reader away from hidden hinges or reinforcement plates.
• Read-Range Testing on Retrofit: If replacing an older reader, test the 5365EGP00 read range with existing credential stock in situ before final mounting. Proximity card read distance varies with coil design; if your existing cards barely trigger at 6 inches, verify the new reader achieves the same distance or better.
• No Credential Encryption: 125 kHz proximity credentials are unencrypted and vulnerable to cloning. This reader is not suitable for high-security zones, server rooms, or audit-critical areas. Consider 13.56 MHz encrypted readers for those applications.
• Wiegand Wiring Polarity: Wiegand uses polarity-sensitive signaling—confirm your panel's Wiegand input is wired to the same convention (Data0, Data1, common ground). Reversed polarity results in no communication. Check the panel datasheet and test with a continuity meter before closing walls.

This reader is the right choice for integrators managing large-scale 125 kHz proximity deployments, retrofit projects where credential replacement is cost-prohibitive, or sites with legacy access control panels that lack OSDP or IP support. If you're building a greenfield installation or supporting a facility that prioritizes audit logging and mobile credentials, evaluate encrypted smart-card readers instead. For sites that need reliable mullion-mount proximity reading today, with minimal system disruption and zero credential replacement, the 5365EGP00 is a proven workhorse.
