How Does the Touchless Exit Button Work?

🔵 Standby — Ready

During standby operation, the IR-T4B displays a
blue LED indicator.

The sensor monitors the configured detection area and
remains ready to respond when a hand approaches.

🟢 Hand Detected — Exit Request Activated

When a hand enters the configured sensing range, the
sensor detects the activation without requiring 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 system.

The sensing distance can be adjusted between
5–20 cm.
