Datasheet

CS **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. 

**Note:** Be sure to refer to the Precautions on page 131.

## ~~Precautions~~ 

## **Safety Relays** 

A Safety Relay is a Relay with which a safety circuit can be configured. 

## **Wiring** 

Use one of the following wires to connect to the P7SA-10F/10FND/14F/14F-ND. 

Stranded wire: 0.75 to 1.5 mm[2] Solid wire: 1.0 to 1.5 mm[2] 

## **Cleaning** 

The G7SA is not of enclosed construction. Therefore, do not wash the G7SA with water or detergent. 

## **Forcibly Guided Contacts (from EN50205)** 

If an NO contact becomes welded, all NC contacts will maintain a minimum distance of 0.5 mm when the coil is not energized. Likewise if an NC contact becomes welded, all NO contacts will maintain a minimum distance of 0.5 mm when the coil is energized. 

Tighten each screw of the P7SA-10F/10F-ND/14F/14F-ND to a torque of 0.98 N � m securely. 

Wire the terminals correctly with no mistakes in coil polarity, otherwise the G7SA will not operate. 

## **ALL DIMENSIONS SHOWN ARE IN MILLIMETERS.** 

To convert millimeters into inches, multiply by 0.03937. To convert grams into ounces, multiply by 0.03527.
