The ABB JSHD4-2-AD 2TLA019995R0400 is an ergonomic three-position safety enabling switch designed to allow controlled machine movement when an operator needs to work within or close to a hazardous area. Part of the established ABB Jokab Safety JSHD4 range, this handheld enabling device combines the three-position safety function with integrated LEDs, a front push button and a top push button.
The three-position operating principle is particularly suited to troubleshooting, programming, test running, adjustment and maintenance. Machine operation can be enabled while the actuator is deliberately held in its centre position; releasing the actuator or pressing it fully provides a stop condition through the associated safety control system. This gives the operator an intuitive means of reacting if a hazardous situation develops.
The JSHD4-2-AD configuration combines the feature-rich JSHD4-2 upper section with an 8-pole M12 male connector for quick and convenient machine connection. Operating at 24 V DC and featuring an IP65 enclosure, it provides a robust solution for machine builders and automation engineers requiring a compact handheld enabling device for demanding industrial environments.
Three-position enabling devices are used when personnel need controlled access to machinery during operations that cannot always be performed with normal perimeter safeguards active. The ABB JSHD4-2-AD allows the safety system to permit limited machine movement while the operator deliberately maintains the enabling actuator in its centre position.
If the operator releases the enabling actuator or presses it fully in response to an unexpected situation, the enabling condition is removed so that the associated safety system can initiate a stop. The additional front and top push buttons can be incorporated into machine-control functions, while the LEDs provide visual indication and the M12-8 connection simplifies installation, replacement and servicing.

The JSHD4-2-AD is a three-position safety enabling device used to permit controlled machine movement during troubleshooting, programming, test running, adjustment and maintenance operations.
The device provides an enabled condition while its actuator is deliberately held in the centre position. Releasing the actuator or pressing it fully removes the enabling condition so that the associated safety control system can stop hazardous machine movement.
The JSHD4-2-AD incorporates LED indicators, a front push button and a top push button, providing additional indication and machine-control functions alongside the three-position enabling switch.
The JSHD4-2-AD uses an 8-pole M12 male connector, providing a compact and convenient connection to the associated machine safety and control system.
The JSHD4-2-AD has an IP65 degree of protection, making it suitable for use in demanding industrial machine environments when correctly installed.
ABB Jokab Safety JSHD4 enabling devices are designed for machine builders and automation engineers who require controlled machine operation during setup, testing and maintenance. The JSHD4-2-AD combines three-position enabling control, auxiliary push buttons, LED indication and a convenient M12-8 connection in an ergonomic industrial handheld device.
