The HID GLOBAL CORPORATION 20NKS-01-01A06H is a Signo 20 smart card reader designed for access control applications. Finished in black and silver, this reader uses a pigtail wiring connection and is configured with a card profile credential format. It is typically installed by licensed security integrators and low-voltage electricians as part of electronic access control systems in commercial and light industrial environments. The compact form factor and pigtail output make it suitable for panel-side termination in standard access control enclosures.
The Signo 20 reader is suited for interior and exterior door access points in commercial buildings, office environments, and secured facilities. The card profile configuration is set for use with HID credential formats. Installation is performed at the door hardware level, with wiring routed back to an access control panel or controller. No specific model compatibility data was provided beyond the product series designation.
Designed as an OEM-style replacement or direct-install smart card reader for commercial access control systems compatible with HID Signo 20 series readers using pigtail wiring and card profile credential formats.
Installation should be performed by a licensed low-voltage electrician or certified access control integrator. Power down the access control panel and associated door hardware circuits before wiring. Follow local low-voltage and NEC code requirements for signal wiring runs. Do not apply line voltage to the reader wiring harness.
