No Touch To Exit With Metal Casing 

 

No Touch To Exit With Metal Casing

A No-Touch Exit Button (with metal casing) is a device used in access control systems to unlock a door from the inside without physically pressing a button.

Instead of pushing a switch, you simply wave your hand near the sensor, and the door unlocks. This is why it’s often called “wave-to-exit” or “touchless exit.”

How it works

The device uses an infrared sensor to detect a hand movement within a few centimeters.

When it detects motion, it sends a signal to the door controller or lock.

The electric lock or magnetic lock releases, allowing you to exit.

Detection distance is usually 5–15 cm, so you just wave your hand in front of it.

Why it has a metal casing

The metal (usually stainless steel) casing is used because:

✔️ Durability – strong and vandal-resistant

✔️ Weather resistance – works indoors or outdoors

✔️ Professional finish for offices or buildings

✔️ Long lifespan even in high-traffic areas
