The HID GLOBAL CORPORATION 40NKS-00-01BD08 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 pigtail wiring and reads standard card profiles. Mobile Access Enabled (MA ENB) capability allows the unit to authenticate both physical cards and mobile credentials over Bluetooth or NFC. This reader is installed by licensed security and low-voltage electricians in commercial and residential access control applications.
The Signo 40 is suited for door and gate access control installations where both traditional proximity or smart cards and mobile device credentials must be supported. Its pigtail connection style is compatible with standard access control panel wiring practices. The standard card profile configuration makes it a straightforward drop-in for typical credential management deployments across office, industrial, and institutional environments.
Designed as an OEM-style replacement or new-install smart card reader for standard access control systems accepting pigtail-wired Signo-series readers with mobile access support.
Installation should be performed by a licensed low-voltage electrician or certified access control technician in accordance with NEC low-voltage wiring requirements. Disconnect and de-energize the access control panel before connecting or disconnecting the reader pigtail leads. Verify credential compatibility with the connected access control panel firmware before commissioning. Do not expose the reader to direct water ingress unless the installation environment is confirmed suitable for the unit.
