LTS Infrared Request‑to‑Exit Sensor – LTK‑SREX‑100 (UL‑294, Adjustable)

The LTS LTK‑SREX‑100 is an active-focused infrared request-to-exit (REX) sensor designed for secure door egress. Engineered for precision, it creates a narrow detection zone positioned above the door handle to prevent accidental triggers from cross-traffic or placed objects.

Designed to integrate seamlessly with magnetic locks and access systems, the sensor operates on 12–24 VAC/VDC, auto-selects voltage, and draws approximately 60 mA. A built-in DPDT relay (rated 2 A @ 30 VDC/24 VAC) supports timed egress with adjustable delay from 1 to 60 seconds.

Key resistances include immunity to thermal shifts, pets, and concealed activation attempts—ensuring reliability in high-security environments. A muted buzzer with on/off DIP control provides install-time feedback, while UL standards (UL‑294 & ULC‑S319) confirm its egress device certification. Installation is made easy using a 14-pin connector with a 4-foot cable.
