ABB JSHD4-3-AE 2TLA019995R1600 is an ergonomic three-position safety enabling switch with LED indication, an integrated emergency-stop button, an 8-pole M12 connection and IP65 protection for controlled industrial machine operation.
The ABB JSHD4-3-AE 2TLA019995R1600 is an ergonomic three-position safety enabling switch designed for controlled operation of industrial machinery during setup, programming, troubleshooting and maintenance. Part of the ABB Jokab Safety JSHD4 range, it combines a three-position enabling function with integrated LED indication and an emergency-stop control.
The three-position operating principle enables controlled machine movement while the operator deliberately holds the actuator in its centre enabled position. Releasing the actuator or pressing it fully removes the enabling condition, allowing the associated safety system to stop hazardous machine functions. This makes the JSHD4 particularly suitable for tasks where authorised personnel need access within safeguarded machinery areas.
The JSHD4-3-AE combines a JSHD4-3 upper section with LED indication and no additional auxiliary buttons with an AE lower section featuring an 8-pole M12 connection and emergency-stop button. This configuration integrates enabling and emergency-stop functionality into one ergonomic handheld device for convenient machinery safety control.
Three-position enabling devices are used where authorised personnel need controlled machine movement during operations that require access inside or close to a safeguarded area. The ABB JSHD4-3-AE allows the enabling condition to be maintained only while the operator deliberately holds the actuator in its intended centre position, providing an intuitive safety interface during commissioning and servicing.
The addition of an integrated emergency-stop button gives the operator immediate access to a separate emergency stopping control from the same handheld device. Combined with LED indication, an 8-pole M12 connection and an IP65 enclosure, the JSHD4-3-AE provides a practical solution for demanding machinery safety and automation applications.
