ABB JSHD4-4-AD 2TLA019995R2600 is an IP65 three-position safety enabling switch with integrated LEDs, a front auxiliary push button and an 8-pole M12 connection for controlled industrial machine operation.
The ABB JSHD4-4-AD is an ergonomic three-position safety enabling switch designed to provide controlled machine operation when an authorised operator needs to work within or close to a hazardous machine area. Identified by ABB order code 2TLA019995R2600, it forms part of the ABB Jokab Safety JSHD4 series of handheld safety control devices for industrial machinery and automation applications.
The JSHD4-4-AD combines a three-position enabling mechanism with integrated LED indicators and a front auxiliary push button. Machine movement can be permitted while the operator deliberately maintains the enabling device in its intended operating position, while releasing or fully depressing the actuator changes the safety contact state. This makes the device particularly suitable for commissioning, troubleshooting, programming, adjustment and test-running operations.
This configuration combines the JSHD4-4 top section with the AD bottom section, providing a convenient 8-pole M12 male connection for quick integration into industrial machine safety systems. Its compact IP65-rated construction, ergonomic handheld design and safety performance of up to PL e make it a dependable solution for operator-controlled machine movement in demanding automation environments.
Three-position enabling devices are used where machine setup, commissioning, maintenance or programming requires an operator to remain close to potentially hazardous machine movement. The ABB JSHD4-4-AD provides deliberate operator-controlled enabling so that permission for movement can be linked to continuous intentional operation of the handheld device.
The JSHD4-4-AD also incorporates LED indication and a front auxiliary push button, allowing additional operator feedback and control functionality from the same handheld unit. Its 8-pole M12 connection provides a convenient alternative to hard-wired cable-gland versions of the JSHD4, helping simplify installation, replacement and maintenance within compatible machine safety systems.
