ABB JSHD4-5-AB-A 2TLA019995R3500 is an ergonomic three-position safety enabling switch with integrated LED indication, a top auxiliary push button, a 12-pin Cannon male connection and anti-tamper functionality for industrial machinery.
The ABB JSHD4-5-AB-A 2TLA019995R3500 is an ergonomic three-position safety enabling switch designed for controlled machine operation during troubleshooting, test running, programming, setup and maintenance. Part of the ABB Jokab Safety JSHD4 range, this complete handheld safety control device combines the three-position enabling function with integrated LED indication, a top auxiliary push button and anti-tamper functionality.
The three-position operating principle provides a deliberate enabling function for situations where authorised personnel need to operate machinery while working within or close to a safeguarded area. Machine movement can be permitted while the actuator is intentionally maintained in its enabled position, while releasing the actuator or pressing it fully removes the enabling condition so that the associated safety control system can initiate the required stop.
The JSHD4-5-AB-A combines the JSHD4-5 upper section, featuring LEDs and a top push button, with the robust AB lower section providing a 12-pin Cannon male connection. The additional anti-tamper PCB distinguishes this version from the standard JSHD4-5-AB and provides enhanced monitoring of the enabling-device operation.
Three-position enabling devices are designed for applications where authorised personnel need controlled machine movement during work that requires access inside or close to hazardous machinery areas. The ABB JSHD4-5-AB-A provides a deliberate enabling interface that can form part of the machine safety system during setup, programming, adjustment and diagnostic operations.
The integrated top auxiliary push button provides an additional operator-control function, while the LEDs offer convenient visual indication. Combined with the robust 12-pin Cannon connection and anti-tamper PCB, the JSHD4-5-AB-A provides a comprehensive handheld solution for machine builders and automation engineers requiring controlled access to industrial machinery.
