Failure to follow these instructions can result in death, serious injury, or equipment damage. |
This diagram shows the external dimensions of the TM3SAK6R / TM3SAK6RG safety modules:
* 8.5 mm (0.33 in.) when the clamp is pulled out.
The TM3SAK6R• module is a safety module for monitoring emergency stop and limit switches on protective guards, safety light curtains, and safety-mats according to ISO/EN 13849, IEC/EN 62061, IEC/EN 61058. The module has these safety-related characteristics:
