HID 1346LNSMN ProxKey III Proximity Key Fob
Overview
The HID 1346LNSMN is a programmable ProxKey III key fob operating at 125kHz — a passive proximity credential designed to work with any HID proximity reader in your access control system. At 0.24 oz, it fits wallet slots or clips to a keychain without adding bulk, making it practical for high-turnover environments (visitor management, temporary contractor access, or distributed multi-building campuses) where card stock would get lost or damaged. The passive (battery-free) design means no maintenance, no replacement cycles — credential lifespan is indefinite unless physically damaged.
Compatibility
This fob pairs with all HID proximity readers that accept 125kHz credentials — including the HID 5365, 5375, 5395 series readers and compatible third-party proximity infrastructure already deployed on your doors. The 1346LNSMN is field-programmable and supports formats up to 85 bits, accommodating over 137 billion unique codes — enough address space for enterprise-scale identity schemes without collision risk. Supports sequential matching number assignment with no slot design, simplifying issuance workflows where credentials are pre-printed with matching numbers for compliance documentation.
Key Deployment Factors
Read range: Typical proximity fobs read reliably at 6–12 inches depending on reader orientation and material obstruction (metal keychains, wallets lined with RFID shielding can reduce range). Test in your specific mounting environment before rolling out fleet-wide. Durability: ABS construction is resistant to cracking and moisture but not rated for continuous submersion or salt-spray corrosion — suitable for indoor/covered outdoor (parking garages, loading docks) but not seacoast or chemical-wash facilities. Strap/clip options: Fobs are supplied with external strap and clip accessories, allowing mounting as a photo ID badge or keyring attachment based on your security culture.
