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.

CE marking.
