G7S Safety Relay
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.

- Page 7 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.
