The HID® Signo™ 40 T2 is a high-frequency access control reader built for environments where a clean, wall-flush install matters — it mounts directly onto a standard wall switch box with terminal block wiring, keeping cabling tidy and the finish professional. A surface detection feature means the reader automatically recalibrates its read range based on the material it's mounted on, so you're not chasing performance issues after installation.

Multi-frequency compatibility gives you real flexibility when managing a mixed-credential environment, and HID Mobile Access® support via native Bluetooth and NFC means staff can present a smartphone or wearable just as easily as a physical card. The reader also works fully with HID Reader Manager, so configuration and updates can be handled remotely — useful when the reader is already fixed to a wall in a busy corridor.

An Intelligent Energy Saving Mode reduces power draw when the reader is idle, which adds up across a larger installation. The kind of device that earns its place in a well-planned access control upgrade — particularly where you're migrating existing infrastructure without wanting to rip everything out and start again. Manufacturer part number: 40TKS-T2-000000.
