JSHD4
JSHD4 is a three-position device used to allow a limited movement of the machine when the operator is in the dangerous area, for example during troubleshooting, test running and programming.
The operator pushes the larger black button to a middle position to allow movement. In case of danger, the operator will either release the button or squeeze it to its bottom position and the machine will stop.
JSHD4 is available with different types of connectors for an optimal adaptation to the application. Some models offer additional top and front button to control a non-safe signal.
Features and benefits
Optimum interface
- Red/green LEDs available to give visual status to operators
- Auxiliary buttons for additional functions
- Modular design and various connection options
Continuous operation
- Optional protection coat allows the JSHD4 to be used in harsh environments
- Allows the operators to safely inspect the manufacturing process without completely stopping the machine
Safety and protection
- An “anti-tamper” option is available that detects if the JSHD4 is held in the middle position by a human hand rather than other means (e.g. elastic band)
- Highest level of safety category 4/Ple.
Application
Used in applications where an operator is in the hazardous area and only limited movement of the machine is allowed. This allows the operator to be in full control and safely inspect a manufacturing process without completely stopping the machine. Examples are robotic cells and automated equipment bypassing, machine adjustments and teach or maintenance processes.
