The STB Self-checking Optical Touch Button is a photoelectric-based, manual activation device designed to provide an ergonomic alternative to conventional mechanical push buttons and palm buttons.
The STB creates a pulsed infrared beam that spans its touch zone. The buttons switch when their light beam is broken by a simple insertion of a finger.
No pushing is necessary, eliminating the hand, wrist and arm stresses that may result from repeated push button operation.
This reduces harmful tendon, nerve and neurovascular disorders.
Duo-Touch® SG Two-hand Control Safety Modules
This new two-hand-control safety module is designed to verify proper operations of two-hand-control devices, for increased control reliability in anti-tiedown applications.
The DUO-TOUCH SG uses a diverse-redundant microcontroller circuit to monitor one normally-open and one normally-closed contact set on each hand control device.
If either device is released, the DUO-TOUCH SG cancels its output signal.
