## GENERAL PURPOSE ACCESSORIES 

## **INTRODUCTION** 

Relay accessories are devices to support the design and maintenance of relays in electrical circuits. This relay series include clips, mounting adapters and sockets. Mounting adapters provide adaptation between standard socket types. Sockets are used for relay mounting in configurations, including panel mount, PCB types and DIN rail and clips are used to secure the relay in the connector. 

## FEATURES 

- Sockets for 1 - 3 pole relays with .187” (4/75mm) quick connects 

- Solder, PCB or screw terminal sockets 

- Hold down springs 

- Various mounting options 

## APPROVALS 

- UL E59244 

- CSA LR15734 

## U

## **Caution:** 

Printed circuit sockets are manufactured with “floating” (Loose) terminals. This permits them to align with holes in the circuit board and with the relay terminals. During the mounting and soldering of the socket, vertical float should be eliminated and the terminals seated on the board. (This may be accomplished by inserting a dummy relay in the socket.) Failure to eliminate float may cause fracture of the solder joint or separation of the copper conductor from the printed circuit board when a relay is inserted in the socket after soldering.
