HID Signo 20 Access Control Reader, Terminal Strip, Black with Silver Trim

Please note: this is a non-returnable item (excluding faulty goods)

The HID Global 20TKS-00-00003U is a Signo 20 contactless access control reader with terminal strip wiring, finished in black with a silver trim.

The Signo 20 is a narrow-format reader from HID's Signo line, sized for a door frame or the strip of wall beside a leaf rather than a broad flat surface. At 121.4mm tall, 45mm wide and 19.6mm deep it takes up very little of the frame, and at 75.1g it puts almost no load on the fixing. This is the terminal strip version, so the cable lands on screw terminals inside the reader, which suits a back box that already has the cable waiting in it.

Credentials are presented rather than swiped: the reader identifies contactless cards and fobs by RFID and also supports Bluetooth credentials over 2.4GHz. HID wires the same two terminals as Wiegand data or as RS-485 for OSDP, marked dependent upon reader configuration, and gives a 12V DC input. It can be surface mounted or mounted on the door itself, and it is stated as RoHS and WEEE compliant.

Key features

• Signo 20 narrow format: The body measures 121.4mm x 45mm x 19.6mm, so it fits a door frame or a narrow reveal where a wider reader will not.
• Terminal strip wiring: The cable terminates on screw terminals inside the reader.
• Standard credential profile: The order code carries HID's Standard Profile, which reads Seos, iCLASS and MIFARE cards as well as 125 kHz HID, Indala and EM4102 proximity.
• Bluetooth credentials: The reader also accepts 2.4GHz Bluetooth credentials as well as contactless cards.
• Wiegand or OSDP: HID wires terminals 3 and 4 as Wiegand Data 1 and Data 0 or as RS-485 A and B, and marks that assignment dependent upon reader configuration.
• 12V DC input: A 12V DC input is listed for this reader, which is the usual rail on a door controller.
• Surface or door mount: It can be fixed to a wall surface or mounted on the door itself.
• Environmental compliance: The product is stated as RoHS compliant and WEEE compliant.

Use cases

A narrow reader like this goes where a wall-switch sized one will not. Typical positions are the mullion of an aluminium shopfront, the frame beside a glazed office door, a lift landing, or a door leaf itself. It also fits the narrow return beside a fire door, where there is barely a hand's width of flat surface.

It suits the everyday commercial jobs: an office suite, a school block, a surgery, a warehouse office corridor, a plant room door. On those jobs each door needs a reader on the outside, and the controller sits back in a riser or a comms cupboard. The Wiegand output means it will drop into an existing controller that is already reading Wiegand from an older reader.

It is a common choice when a site is replacing tired readers a door at a time, rather than pulling the whole system out.
