The ABB JSHD4-2-AB-A 2TLA019995R0300 is an ergonomic three-position safety enabling switch designed for controlled operation of industrial machinery when an operator needs to work inside or close to a hazardous area. Part of the established ABB Jokab Safety JSHD4 range, this complete handheld enabling device combines a three-position actuator with additional controls, LED indication and anti-tamper functionality.
A three-position enabling device provides a practical method of permitting machine movement only while the actuator is deliberately held in its centre enabled position. Releasing the device or applying excessive pressure moves the actuator away from the enabled state, allowing the associated safety control system to stop hazardous machine functions. This operating principle makes the JSHD4 particularly suitable for setup, programming, troubleshooting and maintenance tasks where personnel require controlled access to machinery.
The JSHD4-2-AB-A configuration includes LEDs, a front push button and top push button, a 12-pin Cannon connection and an anti-tamper PCB. Its ergonomic handheld design supports comfortable operation while providing the additional controls required for sophisticated machine commissioning and maintenance applications.
Three-position enabling switches are commonly used where an operator must temporarily permit machine movement while carrying out commissioning, adjustment, programming or maintenance work. The ABB JSHD4 operating principle requires deliberate actuation to the enabled position, helping prevent unintended machine operation when the device is either released or gripped beyond its enabled position.
The JSHD4-2-AB-A extends this functionality with additional front and top push buttons, LED indication and anti-tamper electronics. These features make it suitable for advanced machinery where the operator needs auxiliary commands and clear visual feedback from a single ergonomic handheld control device.

The JSHD4-2-AB-A is a three-position safety enabling device used to permit controlled machinery operation during tasks such as setup, programming, adjustment, troubleshooting and maintenance.
The enabling function is designed so that machine operation can be permitted while the actuator is deliberately held in its centre enabled position. Releasing the actuator or pressing it beyond the enabled position removes the enabling condition so that the associated safety system can stop hazardous movement.
The 2TLA019995R0300 configuration includes red and green LEDs, a front push button and a top push button, providing additional control and indication functions for machine operation.
The JSHD4-2-AB-A uses a 12-pin Cannon connector for connection to the associated machine safety and control system.
Yes. The JSHD4-2-AB-A incorporates an anti-tamper PCB, distinguishing it from equivalent JSHD4 configurations without the anti-tamper option.
ABB Jokab Safety JSHD4 enabling devices are designed for machinery applications where operators require controlled access during setup, programming and maintenance. The JSHD4-2-AB-A combines three-position enabling control with auxiliary buttons, LED indication, a 12-pin Cannon connection and anti-tamper functionality in an ergonomic handheld device.
