Description
👋 IR-T15B Touchless Surface Mount Exit Button
The IR-T15B is a slim touchless surface-mount
exit button designed for access control and door release applications.
Users can request exit without physically touching the device,
providing a convenient contactless solution for controlled doors.
The unit operates on DC12–24V and provides
NO / NC / COM output contacts, with an adjustable
5–20 cm sensing distance and
0–30 second time delay.
Touchless Operation
Activates without physical contact.
Simply move a hand within the configured sensing area
to initiate the exit request.
5–20 cm Sensing
Adjustable sensing distance allows the detection range
to be configured according to the door location and
installation requirements.
0–30s Adjustable Delay
The output delay can be adjusted from 0 to 30 seconds,
providing flexibility for different access control and
door release configurations.
Two-Colour LED
Blue indicates normal standby operation, while green
provides a clear visual response when the sensor has
been activated.

How Does the Touchless Exit Button Work?
🔵 Standby — Ready
During normal standby operation, the IR-T15B displays a
blue LED indicator.
The sensor monitors the configured detection area without
requiring any physical contact. The unit remains ready to
detect a hand approaching the sensing zone.


🟢 Hand Detected — Exit Request Activated
When a hand enters the configured sensing range, the
IR-T15B detects the activation without physical contact.
The LED changes from blue to green to
indicate a response, while the
NO / NC / COM output changes state
according to the connected access control or door release system.
The sensing distance can be adjusted from
5–20 cm, allowing the activation range
to be configured according to the installation environment.
