Narrow RFID Reader for Door Access

The HID Signo Reader 20 is a narrow-profile device built for door-mounted access control. It reads a wide range of credential technologies including cards, fobs and mobile devices. The unit supports HID Mobile Access via native Bluetooth and NFC, plus Apple Enhanced Contactless Polling for Apple Wallet credentials. It suits installations where a slim form factor is required.

Sustained Operation with Secure Element

Ultra secure storage of cryptographic keys on certified secure element hardware protects data during continuous use. A surface detection feature automatically recalibrates and optimises read range performance over time. Out-of-the-box support for Open Supervised Device Protocol enables secure bidirectional communication. Remote management capability allows configuration without physical interaction.

Verify Mounting Space and Wiring Needs

The reader measures 4.4958 L x 12.0904 W x 18.0086 H centimeters and weighs 0.308 kilograms. Check that the narrow door mullion or frame accommodates these dimensions. A pigtail wiring option is available; confirm the termination method matches your access control panel. Ensure the mounting location allows Bluetooth and NFC signals to reach presented credentials.

Questions about this item

How much power does the Signo 20 draw when it runs continuously all day?

The reader is powered through its pigtail wiring connection and draws the low current typical of OSDP access-control devices, so it adds negligible load to a 12 VDC supply.

What existing wiring or controller must I already have to install the 20KNKS-00-000000?

You need an OSDP-capable access control panel or controller with a 12 VDC power output and a compatible wiring path for the reader's pigtail leads.

Will the Signo 20 work alongside my older Wiegand-only readers on the same system?

It communicates via OSDP, so the host panel must support OSDP; legacy Wiegand readers can remain on other ports, but this reader cannot fall back to Wiegand signalling.
