Touchdown!™ Palm Buttons

PALM BUTTON ASSEMBLIES

To meet OSHA and ANSI safety requirements, the two run/inch buttons must be protected against accidental operation (with ring guards) and they must be separated to require the use of both hands to operate them. They must also be mounted at the proper safety distance if they will be used as a point-of-operation safeguard. Touchdown!™ capacitive palm buttons can replace existing electromechanical manually operated palm buttons or they can be used for new installations. A 24-V DC or 115-V AC connection is required for each palm button; no other parts are required. They can be used on most machines where hand initiation is required. They also meet the UL 491 standard for power-operated machine controls and systems.

These proximity palm buttons have a dual-coil design. One coil senses the operator's hand while the second coil remains inactive, allowing normal operation. If stray radio-frequency noise is present, the second coil is activated, preventing palm button operation. This feature, plus the built-in dual relay output contacts, provides control-reliable palm buttons.

Sealed housing construction and fixed sensitivity set at the factory prevents tampering.
