HID 921NWNTEKE00BN vs HID HID-920-PTNN: Specification Comparison
Both products are HID-manufactured wired access control card readers designed for door-level credential authentication in commercial and institutional deployments. The 921NWNTEKE00BN is an iCLASS SE RK40 smart card reader using Wiegand output, while the HID-920-PTNN is a MultiCLASS SE RP40 proximity reader using OSDP. Buyers evaluating these units are typically choosing between a legacy-panel-compatible Wiegand architecture and a modern supervised OSDP deployment, with differences in credential frequency support, mobile access capability, and communication security being the primary decision axes.

Which reader supports the credential types and communication protocol required by your access control infrastructure?
The 921NWNTEKE00BN communicates via Wiegand 8-bit output with 100µs pulse width and 1000µs spacing — a well-established, widely supported protocol compatible with virtually all legacy access control panels without rewiring. Its credential support spans iCLASS, SE, and HF migration cards, plus low-frequency credentials (listed as disabled by default), enabling phased migration from older 125 kHz card stock to 13.56 MHz SE credentials without replacing readers.
The HID-920-PTNN communicates via OSDP (Open Supervised Device Protocol), a bidirectional, encrypted, and supervised bus protocol that provides tamper detection and higher communication security than Wiegand. It natively supports both 13.56 MHz high-frequency and 125 kHz low-frequency credentials simultaneously, plus card, fob, and HID Mobile Access-compatible mobile devices. OSDP requires a panel or controller with an OSDP-capable port; legacy Wiegand-only panels are not compatible without an adapter.
How do the two readers compare on mobile access capability, power efficiency, and environmental ratings?
The HID-920-PTNN explicitly supports HID Mobile Access, allowing users to present credentials via a mobile device — a capability not listed in the 921NWNTEKE00BN specifications. The RP40 also features intelligent power management rated at up to 59% energy reduction compared to a baseline not defined in the provided specs. It carries Environmental Product Declaration and Green Circle certifications, indicating a documented sustainability posture.
The 921NWNTEKE00BN carries an IP65 environmental rating, confirming protection against dust ingress and low-pressure water jets — suitable for outdoor installations and industrial environments. No IP rating is stated in the HID-920-PTNN specifications; its installation context is described as indoor wired. The 921NWNTEKE00BN housing is described as a black hardened enclosure. Power type for the RP40 is listed as DC, with AC/DC also noted; the RK40 specifications do not detail supply voltage or current draw.
What are the physical form factor and panel integration differences that affect installation planning?
The 921NWNTEKE00BN is described as an iCLASS SE RK40 reader with a black or white housing with silver trim baseplate. The keypad field in the provided specification lists multiple values ('No Yes (2 x 6 layout) No Yes (3 x 4 layout)'), which is internally inconsistent and cannot be used to confirm or deny keypad presence; buyers should verify this directly against HID's published datasheet. It includes door completion signaling to support electromagnetic lock control, and supports terminal mode with key fob operation.
The HID-920-PTNN is a wall-switch-style proximity reader in a black finish, designed for flush wall-mount installation. No keypad is referenced in its specifications. Its OSDP interface enables bidirectional communication with the panel, supporting remote configuration and status reporting — capabilities Wiegand does not provide. Both units carry a 2-year warranty and wired connectivity.
Which should you choose: the 921NWNTEKE00BN or the HID-920-PTNN?
Our take: The 921NWNTEKE00BN is the stronger choice when the existing access control panel is Wiegand-only and outdoor or industrial deployment is required, given its IP65 rating and explicit legacy-credential migration path from 125 kHz to iCLASS SE. The HID-920-PTNN is the stronger choice when OSDP panel support is available, mobile access via HID Mobile Access is a project requirement, or energy efficiency is a procurement criterion — the RP40 specifies up to 59% power reduction, a figure absent from the RK40 specs. The RK40 provides an IP65 environmental rating not stated for the RP40, making it the documented choice for outdoor or harsh-environment doors. Platform qualifier: the RP40's OSDP requirement is a hard dependency — confirm controller compatibility before specifying it, as Wiegand-only panels will require hardware changes.

Frequently Asked Questions
Which should you choose: the 921NWNTEKE00BN or the HID-920-PTNN?
The 921NWNTEKE00BN is the stronger choice when the existing access control panel is Wiegand-only and outdoor or industrial deployment is required, given its IP65 rating and explicit legacy-credential migration path from 125 kHz to iCLASS SE. The HID-920-PTNN is the stronger choice when OSDP panel support is available, mobile access via HID Mobile Access is a project requirement, or energy efficiency is a procurement criterion — the RP40 specifies up to 59% power reduction, a figure absent from the RK40 specs. The RK40 provides an IP65 environmental rating not stated for the RP40, making it the documented choice for outdoor or harsh-environment doors. Platform qualifier: the RP40's OSDP requirement is a hard dependency — confirm controller compatibility before specifying it, as Wiegand-only panels will require hardware changes.
Can either reader work with my existing Wiegand access control panel?
The 921NWNTEKE00BN outputs standard Wiegand 8-bit signal (100µs pulse, 1000µs spacing) and is designed to integrate with existing Wiegand panels without rewiring. The HID-920-PTNN uses OSDP, which requires a panel or controller with an OSDP-capable port; it is not directly compatible with Wiegand-only panels based on the provided specifications.
Which reader supports mobile credentials like smartphone-based access?
The HID-920-PTNN specifies configurable support for HID Mobile Access, enabling credential presentation via mobile device. Mobile access capability is not listed in the 921NWNTEKE00BN specifications.
Is either reader rated for outdoor installation?
The 921NWNTEKE00BN carries an IP65 rating, confirming suitability for outdoor and industrial environments with dust and water-jet protection. No IP rating is stated in the HID-920-PTNN specifications, which describe it as an indoor wired installation unit.
