Narrow Access-Control Reader

The HID Signo 20 is a compact RFID reader designed for door installations where space is limited. It supports a wide range of credential technologies including cards, fobs and mobile devices. The unit includes a built-in keypad for PIN entry and connects via Bluetooth for mobile access. It is suited for access-control systems that require versatile credential support in a slim profile.

Low-Power Secure Operation

The reader uses a certified secure element for cryptographic key storage and features automatic surface detection to optimise read-range performance. It supports Open Supervised Device Protocol for encrypted bidirectional communication. Remote management allows configuration without physical access to the device. Normal operation draws minimal power and produces no audible noise.

Terminal-Strip Integration

A terminal-strip wiring option simplifies connection to access-control panels and power supplies. The compact dimensions of 4.3942 L x 12.2936 W x 18.2118 H centimetres allow mounting on narrow mullions or door frames. Bluetooth and NFC capability free the system from dedicated card-only infrastructure. The unit weighs 0.34 kilograms and requires no additional reader housing.

Questions about this item

How do I wire the HID Signo 20 20KTKS-00-000000 using the terminal strip option?

Connect the supplied wires to the terminal strip on the back of the reader following the wiring diagram; the step often missed is securing each conductor under the correct labelled terminal before mounting the narrow 4.3942 cm wide housing.

What maintenance will the Signo 20 reader need over time?

The reader has no moving parts or user-replaceable modules; keep the surface clean so the automatic surface-detection recalibration can optimise read range, and apply firmware updates remotely via OSDP when released.

What is the first limit reached under continuous heavy traffic?

The Bluetooth radio and secure element handle sustained credential transactions without thermal throttling; the practical limit is the door controller’s transaction queue, not the reader itself.
