The HID GLOBAL CORPORATION 40NKS-00-01K8L2 is the Signo 40 smart card reader, a compact credential reader designed for access control applications. Finished in a black and silver housing, it reads standard card profile credentials and ships with mobile access enabled, allowing facilities to support both physical cards and mobile device-based credentials on the same reader. This unit is sold individually and is installed by security integrators, low-voltage electricians, and access control technicians as part of a broader door access system.
The Signo 40 is suited for interior and exterior access control deployments in commercial and light industrial environments. Its pigtail wiring configuration connects directly to access control panels and door controllers. Mobile access enablement makes it a practical choice for facilities migrating from legacy card-only systems to smartphone-based or multi-credential environments.
Designed as an OEM-style replacement and new-installation smart card reader for standard access control panel wiring configurations that support Wiegand or similar low-voltage reader interfaces.
Installation is typically performed by a licensed low-voltage technician or security integrator. Power down the access control panel before connecting or disconnecting the reader pigtail wiring. Follow NEC low-voltage wiring guidelines and the panel manufacturer instructions for reader port configuration. Verify mobile access feature activation requirements with the access control platform in use before commissioning.
