G7S Safety Relay G7S Safety Relay conforming to EN standard Conforms to prEN50205. 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. CE mark (EC Low-voltage Directive 73/23/EEC) Track-mounting and Back-mounting Sockets are available. Note: Be sure to refer to the Precautions on page 7.

Relay Removal Tool P7S-B 6 G7S G7S Precautions Forcibly Guided Contacts When NO contacts are welded, the coil will be non-energized so all NC contacts will maintain a distance between the contacts of 0.5 mm mini- mum. Likewise if NC contacts are welded, the coil will be energized so all contacts will maintain a distance between each other of 0.5 mm minimum. Application ! Caution Do not touch the terminal area of the Relays or the socket ter- minal area (charged area) while power is ON. Electric shock will result. Safety Relays A Safety Relay is a Relay with which a safety circuit can be config- ured. For common precautions when using and handling Relays, re- fer to OMRON’s Relay Catalog. Contacts The coil terminals have polarity (positive and negative).Operation is not possible if these are connected in reverse. 7 G7S G7S ALL DIMENSIONS SHOWN ARE IN MILLIMETERS.
