Safety Relay G7SA
Slim Safety Relays Conforming to EN
Standards
The forcibly guided contact in the G7SA assures
safe operation (EN50205 Class A, approved by
VDE.)
Ideal for use in safety circuits in press machinery,
machine tools, and other production machinery.
Four-pole and six-pole Relays are available.
The Relay’s terminal arrangement simplifies PWB
pattern design.
Reinforced
insulation between inputs and outputs.
Reinforced insulation between some poles.
UL, CSA approval pending.
