The MSA is a standalone, non contact safety switch with its own internal monitoring system that uses two force guided mechanical contacts, maintaining PLe/Cat4 (ISO13849-1) even when switches are connected in series.
They can be mounted to guard doors to provide and maintain a high level of functional safety without the need to connect to a safety monitoring device such as a safety relay or PLC.
The MSA is housed in a mirror polished stainless steel 316 housing (Ra4) and can be used in virtually any environment including high pressure cleaning following contamination from foreign particles. The housings are compact and easy to fit on less than 40mm frame sections.
Dual Actuator versions are also available for use with “double door” guards. The typical sensing distance “on” is 12mm with wide tolerance to guard misalignment after setting.
All standalone switches employ 2 Force Guided Mechanical Relays and incorporate internal checking to ensure both relays are operational after each safety demand. If one relay fails to open or becomes inoperative the switch will lock out safe.
