HID 20NKS-00-00003U Signo 20 Mullion Reader, Standard Profile, 26-Bit Wiegand, Pigtail, Black with Silver Trim

Deliver reliable, space-efficient access control at entrances where every inch matters with the HID Global Signo 20 Mullion Reader. This smart reader combines industry-leading security with flexible credential options — including 26-bit Wiegand, Bluetooth and NFC — so you can support cards, fobs and mobile IDs without complex retrofits. The Signo 20’s EAL5+ secure element and native OSDP secure channel safeguard authentication data, reducing the risk of cloning and unauthorized access for enterprise-grade physical security and monitoring.

Built for both indoor and outdoor use, the reader’s IP65-rated enclosure and tamper-resistant design provide long-term durability in demanding environments. Installers benefit from pigtail wiring and RS-485 compatibility for quick integration into existing access control panels and surveillance networks. Ideal for mullion mounting on doors, frames and portals, the Signo 20 streamlines multi-factor authentication deployments while supporting migration paths for legacy 125 kHz credentials.
