BEA’s IXIO-ST is an effective, versatile and easy-to-use safety sensor for automatic sliding doors. It can be used for both clear door openings and side-lite protection.

Precise infrared curtains coupled with visible alignment beams make the IXIO-ST extremely safe and easy to adjust. This state-of-the-art sensor features an on-board LCD screen that streamlines the installation and setup processes.

The IXIO-ST can be adjusted into an ANSI compliant solution and has earned a comprehensive list of credentials and certifications, including UL, FCC and IP54. This sensor is fully monitored internally, capable of external monitoring and has a visible LED to indicate connection between the sensor and door control.
