The HID GLOBAL CORPORATION 40KNKS-00-001TDR is the Signo 40K smart card reader, a credential-reading device designed for access control applications. Finished in black and silver, it connects via pigtail wiring and is built to a card-profile form factor, meaning the unit sits flush and low-profile against the mounting surface. Installers in the commercial security and access control trade deploy this reader as part of an electronic entry system, where it reads smart card credentials and passes authorization data to a connected access control panel.
The Signo 40K is suited for commercial and light-industrial access control installations. Its card-profile housing makes it appropriate for doorframe and mullion mounting where a slim footprint is required. The pigtail output connects directly to access control panels and controllers that accept industry-standard reader wiring. This reader is typically specified by low-voltage security technicians and access control integrators working on new installations or retrofits.
Designed as an OEM-style smart card reader for use in commercial electronic access control systems that support standard pigtail-wired smart readers.
Installation should be performed by a licensed low-voltage or security systems technician in accordance with applicable local codes and NEC requirements for low-voltage wiring. Disconnect and de-energize the access control panel before connecting or disconnecting the reader pigtail leads. Verify that the host panel or controller supports the reader communication protocol before completing the installation. Do not expose the reader to voltages beyond its rated input.
