Operator Interfaces Won’t Stress Wrists

Designed to help alleviate plant managers’ and operators’ concerns about ergonomics and safety, the Allen-Bradley Zero-Force Touch Button line of operator interface devices is said to be the first of its type to incorporate field-effect sensing with microprocessor technology. The units’ contoured surface mimics the shape of the palm, eliminating the need to rotate hands or operate a button with a single finger. The design helps prevent carpal tunnel syndrome and other nerve disorders common with repetitively used operator interfaces. Units are available with 30.5 mm and 2.5 mm mounting options.Unlike traditional pushbuttons, these buttons do not require the operator to apply any pressure to activate them. The sensors register the operator’s touch using field-effect sensing technology that converts human touch into an electrical output.
