Safety Relay G7S Safety Relay con- forming to EN stan- dard Conforms to EN50205. A minimum of 0.5 mm between contacts even when one contact is welded. (prEN50205 Class A) Forcibly guided contacts. The G7S contributes to the protection of machinery when used as part of an interlocking circuit. Most suitable for safety circuits in press machinery, machine tools, and other production machinery. Trackmounting and Backmounting Sockets are available. Note: Be sure to refer to the page G-342. Ordering Information Model Number Legend G7S- A B 1 2 1. NO Contact Poles 2.
