ABB jshd4-2-aj-a Enabling Switch

Why Choose the ABB JSHD4-2-AJ-A 2TLA019995R1100 Enabling Switch?

The ABB JSHD4-2-AJ-A 2TLA019995R1100 is an ergonomic three-position safety enabling switch designed for controlled operation of industrial machinery when an operator needs to work within or close to a hazardous area. Part of the established ABB Jokab Safety JSHD4 range, this complete handheld device combines a three-position enabling mechanism with LED indication, front and top auxiliary push buttons and integrated anti-tamper electronics.

Three-position enabling devices are commonly used during troubleshooting, test running, programming, commissioning and machine adjustment. The JSHD4 allows limited machine movement while the enabling actuator is deliberately maintained in its enabled position. Releasing the actuator or pressing it beyond the enabled position removes the enabling condition, allowing the associated safety control system to stop hazardous machine functions.

The JSHD4-2-AJ-A configuration features a cable gland and an internal PCB with 16 screw connections, providing comprehensive hard-wired access to the enabling contacts, LEDs and auxiliary controls. The integrated anti-tamper PCB is designed to detect attempts to defeat the intended three-position enabling function, making this version particularly suitable for demanding machinery safety applications.

Reliable Three-Position Enabling Control for Industrial Machinery

Three-position enabling switches provide operators with a controlled means of permitting machine movement during tasks that require access inside a safeguarded area. The ABB JSHD4-2-AJ-A uses two enabling contact channels, with the enabled condition maintained only while the operator deliberately holds the actuator in the appropriate operating position.

The AJ configuration is particularly useful for hard-wired machinery because its internal PCB provides 16 screw connections for the enabling contacts, LEDs and auxiliary controls. Combined with the integrated anti-tamper circuitry, front and top push buttons and ergonomic handheld design, the JSHD4-2-AJ-A provides a comprehensive operator interface for machine setup and servicing applications.

Typical Applications

• Industrial machine setup and commissioning.
• Robot programming and teach operations.
• Machine troubleshooting and test running.
• Adjustment within safeguarded machine areas.
• Maintenance and servicing operations.
• Automated manufacturing and assembly cells.
• Production and processing machinery.
• OEM machinery and industrial automation systems.
