Light Beam Finger-Touch Switches

An infrared light beam senses the lightest finger contact to switch a circuit on or off. The included guard prevents accidental activation. An indicator lights up to confirm that switches are actuated. They’re rated NEMA 4X, 13, and IP66 for protection from corrosion, washdowns, and oil/coolant spraying.

Switches with a 5-pole mini plug can quickly be changed out.

Fingerprint Switches

Use fingerprints to confirm the identity of personnel before granting access to secure areas or equipment. Switches light up green to indicate that they have accepted the fingerprint and are sending an output signal. The front faces of the switches meet NEMA 12 and IP65. The rear faces of the switches meet IP20.

Sealed Touch Pad Switches

Suitable for areas with space limitations, these switches have a low profile and a small footprint. They lay flat or mount to a wall. Typically used in start/stop and door opening applications, switches can also be placed underneath objects to alert when the object is removed. All have a sealed housing that resists water and alcohols (not suitable for continuous contact).

Optional mounting frames secure switches to a wall or bench top.
