The ABB 2TLA020005R1900 Jshd4 Bottom Part Ak Cannon Connector is a crucial component designed for the replacement of former non-modular Jokab JSHD4 systems. This bottom part, equipped with a Cannon connector, seamlessly integrates with any JSHD4 top part, excluding the JSHD4-1, to create a complete three-position device. These devices are essential for ensuring safety during machine operations, allowing limited movement when an operator is within a hazardous area, such as during troubleshooting, test running, and programming. Note that this component is not compatible with the anti-tamper PCB, ensuring it meets specific operational requirements.
