The HID GLOBAL CORPORATION 40NKS-03-007761 is a Signo 40 series smart card reader designed for access control applications. It features a black and silver housing with a pigtail cable connection and a card profile form factor. This reader is installed at entry points in commercial and institutional buildings where credential-based access management is required. Security integrators and low-voltage electricians typically handle installation. The compact card-profile design allows for flush or surface mounting at doors, gates, and controlled entry points where a low-profile footprint is needed.
The Signo 40 is suited for commercial access control deployments where modern smart card credentials are used. The pigtail wiring configuration connects directly to access control panels and controllers. Its card-profile housing is appropriate for installations where space is limited or a discreet appearance is preferred, such as office buildings, healthcare facilities, and education campuses. This reader is sold as a single unit per order.
Designed as an OEM-style replacement or new-installation smart card reader for commercial access control systems accepting standard wiegand or equivalent smart reader interfaces.
Installation is typically performed by a licensed low-voltage electrician or certified security systems integrator. Power down and de-energize the access control panel before wiring the pigtail connections to the controller. Follow NEC low-voltage wiring guidelines and the access control panel manufacturer's wiring diagram during installation. Do not expose the reader to direct water intrusion beyond its rated environmental protection during or after installation.
