The HID® Signo™ 40 Reader is designed for organisations that need dependable access control without a complicated installation or a disruptive migration process. It mounts directly onto a standard wall switch box with flush mounting via terminal block wiring — the kind of clean, considered installation that keeps facilities teams happy. A built-in surface detection feature means the reader automatically recalibrates itself to optimise read range based on where it's mounted, removing the guesswork from commissioning.

Credential flexibility is well covered here. The Signo 40 supports HID Mobile Access® through native Bluetooth and NFC, alongside compatibility with multiple card frequency technologies — useful for sites running mixed credential environments or planning a phased migration from legacy systems. Full compatibility with HID Reader Manager keeps configuration and management straightforward from a central point. An Intelligent Energy Saving Mode reduces power consumption when the reader is idle, which matters when you're deploying at scale.

Available in black or white to suit your environment. Terminal connection (pigtail also available separately). Manufacturer part number: 40TKS-00-000000.
