Amid increased awareness of hygiene and safety caused by the COVID-19 pandemic, Safety Technology International (STI - Waterford, MI) announced it has expanded its line of contactless IR switches.

As reckoned by STI:

Hands spread more than 80% of viruses, making health and safety a concern for facilities. With 2-10 million bacteria on a person’s fingertips, commonly touched surfaces are a breeding ground for germs. One of the most touched surfaces is a door handle. Using a touch-free button is an easy solution to help reduce viruses.

Helping business to adapt to this new post-pandemic reality, STI has introduced its NoTouch IR Switches to aid in minimizing physical contact and reduce the risk of virus contraction.

To exit or enter a building without touching the door, a user must simply wave their hand in front of the unit's contactless button. The device's active infrared capability is designed to detect the motion of a wave, send an electrical signal to the door operator, and unlatch the time adjustable door. The switches' touch-free action prevents germs from transferring to hundreds of hands and surfaces, helping to promote health and safety.

STI's NoTouch IR Switches are constructed of medical/food grade 304 stainless steel (NT-SS series) or heavy-duty die cast aluminum (NT-CA series). The switches have a dual color status LED (green/red or red/green), and an approximate 1.5~6 inch detection range.

A stainless steel button is available with operating instruction options: OPEN, EXIT or a door symbol. A cast aluminum button includes three interchangeable snap-in illuminated messages (white OPEN, green EXIT, blue EXIT), and is customizable.
