The HID GLOBAL CORPORATION 40NKS-03-00055V is the Signo 40 smart card reader, a compact access control device finished in a black and silver housing with a pigtail wire connection. The Signo 40 reads contactless smart credentials and transmits access data to a connected access control panel. It is designed for installation at secured entry points including doors, gates, and controlled areas where credential-based access is required. Security integrators and low-voltage electricians are the primary trades installing this device.
The Signo 40 is suited for both commercial and light industrial access control deployments. Its pigtail termination style connects directly to a compatible access control panel or door controller. The black and silver finish gives it a professional appearance appropriate for lobbies, offices, server rooms, and similar environments where both function and aesthetics matter. It ships as a single unit, making it straightforward to order per-door.
Designed as an OEM-style smart card reader for commercial and light industrial access control systems that accept standard Wiegand or supported output protocol connections.
Installation is typically performed by a licensed low-voltage electrician or certified security integrator. Disconnect and de-energize the access control panel before wiring the reader to avoid damage to reader electronics. Route the pigtail leads according to the panel manufacturer's wiring diagram and follow all applicable local codes, including NEC Article 725 for low-voltage control wiring. Verify credential compatibility with the connected access control system prior to commissioning.
