Biometric Switches

Stand-alone biometric switch

The biometric switches of the Harmony® XB5S range are designed to control and secure access to systems and machines by checking users’ authorization through fingerprint recognition.

The following types of biometric switches are available:

  • Stand-alone biometric switches

    • type XB5S1, with 2 fixed states (bistable)

    • type XB5S2, with pulse control (monostable)

  • Stand-alone USB biometric switches

    • type XB5S3, with 2 fixed states (bistable)

    • type XB5S4, with pulse control (monostable)

  • USB biometric switches dedicated to Schneider HMI

    • type XB5S5, connected permanently with HMI

Stand-alone USB biometric switch

The biometric switches are aimed at 2 categories:

  • Administrators, who decide and manage the list of users

    • the only people who can record the fingerprints in the device memory

  • Users, who are authorized to use the biometric switch as a control unit

    • at least 1 of their fingerprints should be recorded in the device memory

    • access is granted when the finger is placed on the sensing screen

The USB switches communicate with the PC/HMI via the USB port to manage the user database. This database can be visualized, saved, and duplicated by PC/HMI with XB5SSoft application [1] [2]. The fingerprint records can also be erased in the absence of users.

The Schneider HMI [3] with VijeoDesigner software [4] enables the switches to authorize different access levels and trace HMI operations of each user.

The switch operates on 24 Vdc and provides protection against:

  • Reverse polarity

  • Overload and short-circuit (switching capacity ≤ 200 mA)


The product is of monolithic design (a single plastic housing) and is mounted by means of a nut (hand-tightened without need for tools) in a standard 22.5 mm/0.886 in. diameter hole. It can be installed on a flat, horizontal, or vertical surface.

A protective cover is available as an accessory to protect the active face of the sensing screen. This cover is mounted using a self-adhesive hinge.

A Female/Female USB extension cable makes it possible for the USB biometric switch to have the female USB port within a 22 mm/0.866 in. diameter hole on the control panel front.

USB biometric switch dedicated to Schneider HMI


  • Conformity to standards: UL, CSA, GOST, and CE

  • Product certifications:

    • CSA C22-2 No. 14

    • UL 508

    • IEC 61000-6-2 and IEC 61000-6-4

  • Degree of protection conforming to standard IEC 60529:

    • IP 65

    • NEMA 12

  • Ambient air temperature:

    • For storage: -13 to 158°F (-25 to 70° C)

    • For operation: 23 to 122°F (-5 to 50° C)


  • The stand-alone biometric switch (XB5S1/XB5S2) consists of a dark gray housing, with the following on its front face:

    • A sensing screen 1 that allows the registration and subsequent recognition of the registered fingerprints,

    • A green LED output state indicator 2 that illuminates when the output is activated (solid-state N.O. contact),

    • An orange LED 3, indicating an administrator’s “Registration” mode,

    • An orange LED 4, indicating an operator’s “Registration” mode,

    • A red “RESET” LED 5 which indicates, in “Delete” mode, that the administrator is deleting all or part of the memory,

    • A red LED 6 which flashes when the reader is presented with an “unrecognized” fingerprint or in the event of incorrect operation.

  • The stand-alone USB biometric switch (XB5S3/XB5S4) consists of a dark gray housing with a sensing screen 1 for fingerprints, a green LED 2 for indicating the output state, and a red LED 6 for the unrecognized fingerprint on its front face.

  • The USB biometric switch dedicated to Schneider HMI (XB5S5) consists of a dark gray housing with a sensing screen 1 for fingerprints on its front face.
