## **INTRODUCTION** 

TE Connectivity (TE)’s Relay accessories are essential devices that support the design and maintenance of relays in electrical circuits. This series of relay accessories includes hold-down springs, mounting adapters, and sockets. Mounting adapters facilitate compatibility between different standard socket types. Sockets are used for relay mounting in various configurations, such as solder and PC terminal sockets, bracket mount sockets, flange mount sockets, and track mount sockets. Additionally, hold-down springs are employed to secure the relay within the connector. 

## FEATURES 

- Sockets for 2 - 6 pole relays 

- Solder, PCB or screw terminal sockets 

- Choice of grounding provision on sockets 

- Hold down springs 

- Plates and brackets permit various mounting options 

## APPROVALS 

- UL E59244 

- CSA LR15734

## **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 beeliminated 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.
