Omron G7S DATASHEET
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.
