The HID GLOBAL CORPORATION 40NKS-00-00C2Y8 is the Signo 40 smart card reader, a compact access control reader designed for credential-based entry systems. Finished in black and silver, it connects via a pigtail wiring harness for direct integration into access control panels and door controllers. The Signo 40 is suited for installations where a reliable, low-profile smart reader is required at the door edge. Licensed access control technicians and security integrators are the primary installers for this type of device.
The Signo 40 reader is used in commercial and light commercial access control deployments. It is typically mounted at entry points including doors, gates, and turnstiles where smart card or credential-based authentication is required. The pigtail connection style makes it compatible with standard Wiegand or OSDP wiring configurations commonly found in commercial security infrastructure. It ships as a single unit (sold individually).
Designed as an OEM-style replacement or new-install smart card reader for commercial access control systems that support standard smart reader wiring interfaces.
Installation is typically performed by a licensed access control or low-voltage security technician. Power down the access control panel before connecting or disconnecting the reader wiring. Follow local low-voltage wiring codes and the panel manufacturer's wiring diagram when terminating the pigtail leads. Verify reader address and protocol settings at the controller before commissioning.
