HID 921PHRNEK0026W RPK40-H PIVClass SE LF Reader

HID 921PHRNEK0026W RPK40-H PIVCLASS Smart Card Reader

Overview

The HID 921PHRNEK0026W is a professional-grade PIVCLASS smart card reader designed for access control, identity verification, and secure credential management in enterprise and government environments. This RPK40-H reader delivers robust multi-protocol support with encryption and tamper detection, making it suitable for high-security door access, checkpoint verification, and integrated security workflows. The reader combines LF (low frequency) and HF (high frequency) standard protocols with optional SEOS, SIO, and FIPS-compliant encryption modes to meet diverse credential ecosystems and compliance requirements.

Key Features

• Dual Frequency Support: LF STD and HF STD/SIO/SEOS modes enable compatibility with legacy and modern credential formats
• PIVCLASS Certification: Purpose-built for PIV (Personal Identity Verification) card environments with FIPS 75-bit encryption and CAK (Cardholder Authentication Key) support
• 485FDX Communication: Full-duplex RS-485 serial interface for reliable multi-drop wiring and extended cable runs in distributed access control systems
• FIPS Compliance: FIPS 75-bit encryption and 4-bit message protocol ensure government and enterprise security standards adherence
• Wiegand Output: Native Wiegand protocol (WIEG ON) for seamless integration with legacy access control panels and controllers
• Tamper Detection: Optional tamper switch (OPT TAMP) provides physical security alerts for unauthorized reader access or removal attempts
• Open Collector Logic: OPEN COLL configuration allows flexible integration with diverse control system architectures
• Single-Key Buffering: BFFRD 1 KEY credential buffering ensures reliable offline operation during network interruptions
• Status Indication: Red LED and flashing green beacon (LED RED, FLSH GRN) provide clear reader status and activity feedback
• No Parity Enforcement: NO PAR configuration maximizes interoperability with legacy systems
• Compact Design: Black enclosure (BLK, STD-1) fits standard access control mounting profiles
• Suppressed Buzzer: Buzzer off (BZR OFF) enables silent operation in quiet or security-sensitive environments

Integration and Compatibility

The 921PHRNEK0026W supports multiple communication and credential protocols, making it a flexible choice for mixed-credential environments. Wiegand protocol (WIEG ON) ensures backward compatibility with installed access control systems, while UART connectivity (UART OFF on this configuration) and 485FDX serial interface provide modern networked alternatives. The reader operates independently of keyboard or host processor control (IPM OFF), allowing standalone credential verification or full system integration. PIVCLASS designation confirms suitability for U.S. Federal identity programs and government contractor environments requiring PIV compliance.

Physical and Operational Specifications

The reader features a durable black enclosure meeting standard industrial form factors. Status LEDs (red and flashing green) and optional buzzer control provide clear operational feedback. The optional tamper switch adds a layer of physical security monitoring. Communication via RS-485 full-duplex (485FDX) enables installation in large campus or multi-building deployments where extended cable runs and noise immunity are critical. The 4-bit message protocol and single-key buffering architecture support high-throughput access scenarios while maintaining offline functionality during system events.
