The HID GLOBAL CORPORATION 40NKS-00-00025H is a Signo 40 smart card reader finished in black and silver with a pigtail wiring connection. The Signo 40 is a compact access control reader designed for credential reading in electronic access control systems. It reads smart card credentials and communicates with access control panels through its pigtail lead, making it a straightforward drop-in reader for new installations and retrofit projects. Installation is typically handled by licensed low-voltage or security system technicians working within commercial or light commercial access control deployments.
The Signo 40 is suited for interior access control applications where a wall-mounted smart reader is required at a controlled entry point. Its black and silver finish blends with standard commercial door hardware and wall plates. The pigtail connection style allows direct termination into an access control panel or reader interface module without a separate connector adapter. This reader is sold as an individual unit and is appropriate for single-door or multi-door access control system builds.
Designed as an OEM-style smart card reader for use with compatible electronic access control panels and reader interface modules that accept standard Wiegand or OSDP reader connections.
Installation should be performed by a licensed low-voltage or alarm systems technician in accordance with applicable local codes and NFPA 731 guidelines. Power down the access control panel and reader interface before making any wiring connections at the reader. Terminate the pigtail leads to the panel or reader board per the panel manufacturer wiring diagram. Avoid routing reader wiring in the same conduit as high-voltage power conductors.
