Hid Global 921NSNNEK20000 Smart Card Reader RK40 Seos Nfc

Product Description

The HID Global 921NSNNEK20000 is a smart card reader in the RK40 series, designed for access control applications requiring multi-technology credential support. This unit reads Seos and NFC credentials and outputs data via Wiegand protocol over a pigtail wire connection. It is housed in a black enclosure and delivers 4-bit data output. Access control technicians and security system integrators install this reader as part of electronic door access systems in commercial and institutional facilities.

This reader is suited for commercial access control deployments where contactless smart card and mobile credential compatibility is required. The Seos technology platform supports high-security credential transactions, while NFC compatibility allows mobile device-based access. The pigtail output connects directly to access control panels and controllers that accept standard Wiegand input. It is typically installed at entry points in office buildings, data centers, healthcare facilities, and other secured environments.

Installation Notes

Installation should be performed by a licensed security systems technician or low-voltage electrician familiar with access control wiring practices. Disconnect power to the access control panel before wiring the reader pigtail to prevent damage to the controller or reader. Follow the access control panel manufacturer wiring diagram when connecting Wiegand data, power, and ground leads. Local low-voltage and security system codes may apply depending on jurisdiction.
