HID Signo 20 Mullion Reader (13.56 MHz, OSDP/Wiegand, Mobile-Ready)

The 20TKS-02-000000 is a Signo 20 mullion-form-factor reader configured for 13.56 MHz operation, OSDP and Wiegand output, and mobile-ready credential support. The mullion form factor is the narrow vertical reader designed to mount on a door mullion or jamb where a wider wall-format reader does not fit.

Key Features

• HID Signo 20 reader in mullion form factor
• 13.56 MHz contactless technology (iClass, MIFARE, DESFire, Seos)
• OSDP and Wiegand output for broad panel compatibility
• Mobile-ready via Bluetooth and NFC for HID Mobile Access
• Narrow vertical profile suited to door-mullion mounting
• Multi-color LED and beeper for clear user feedback
• Suitable for indoor and protected outdoor mounting

The mullion form factor solves the install problem at glass-and-aluminum doors and other narrow mounting surfaces where a wall-format reader does not fit. The narrow profile of the mullion reader mounts cleanly on the door frame's vertical mullion. Functionally the reader is identical to the wall format — same credentials, same OSDP/Wiegand output, same mobile-ready capability — just packaged for a different physical environment.

Verify the mullion has sufficient depth and clear surface for the reader and the cable knockout. Wire the reader for OSDP if the panel supports it; the secure channel resists cloning and replay attacks. Configure the LED and beeper feedback for clear user experience. Test the reader at the actual installed distance with the credential the customer will use day-to-day. For modern deployments, plan the mobile-credential enrollment workflow so executives and contractors can use HID Mobile Access from day one.
