HID ProxPro II 5455 Reader — Newer-Generation Standard Wall 125 kHz Proximity Reader for Chicago Replacements

HID ProxPro II 5455 — Newer-Generation Standard Wall 125 kHz Proximity Reader

The HID ProxPro II 5455 is the newer-generation standard wall single-gang 125 kHz proximity reader from HID Global — replacing the original ProxPro 5355 in new installations with refreshed design, improved read range, and modernized housing. Wiegand output, IP55-rated for indoor and protected outdoor positions.

The ProxPro II 5455 is the Chicago choice for new ProxPro deployments and like-for-like ProxPro 5355 replacements where the newer Mk II generation is preferred for fleet uniformity, current-production parts availability, or specification consistency.

ProxPro II 5455 vs. ProxPro 5355 — When to Choose Which

Need	ProxPro 5355 (original)	ProxPro II 5455 (this — newer)
Form factor	Standard wall single-gang	Standard wall single-gang (refreshed)
Card technology	125 kHz HID Prox	125 kHz HID Prox
Generation	Original ProxPro	Newer Mk II
Best fit	Existing ProxPro fleets, like-for-like cost-tier	New deployments, Mk II specification, current production

For most projects, the choice is specification-driven — match what the ACS controller and existing fleet documentation specifies. Both readers serve the same Prox use case.

When 125 kHz Prox Still Makes Sense

Despite known security limitations (no mutual authentication, cloneable with $50 RFID equipment), 125 kHz Prox is still the right answer for:

• Like-for-like replacement when failed readers need replacement and the entire card fleet stays
• Budget-constrained projects where reader cost is the binding constraint
• Fleet uniformity where existing Prox cards must continue working
• Phased migrations where Prox readers stay at lower-priority positions while Signo / multiCLASS go in at high-traffic positions

For projects where credential migration IS in scope, see multiCLASS SE RP40 (multi-tech: Prox + iCLASS SE / SEOS) or Signo 40 (full multi-tech + mobile).
