The HID GLOBAL CORPORATION 20NKS-00-006QY5 is the Signo 20 smart card reader, a compact access control reader designed for credential verification in electronic security systems. Finished in black and silver, the unit ships with a pigtail wiring lead for direct field termination. The Signo 20 is intended for installation by licensed security integrators and low-voltage electricians working on commercial or light industrial access control deployments. It reads smart card credentials and outputs the access decision signal to a connected access control panel or controller.
The Signo 20 is suited for door-mounted applications in commercial buildings, office environments, and light industrial facilities where smart card or contactless credential access is required. The pigtail connection style supports direct wire termination into panel enclosures or reader interface modules. This reader fits standard mullion and single-gang mounting configurations typical in access control installations.
Designed as an OEM-style replacement or new-install smart card reader for commercial access control systems accepting standard reader interface wiring.
Installation should be performed by a licensed low-voltage electrician or certified security integrator familiar with access control systems. Power down the access control panel and isolate the reader circuit before making wiring connections. Follow the access control panel manufacturer wiring diagram when terminating the pigtail leads. Consult applicable local electrical codes and NEC low-voltage wiring requirements during installation.
