SOCKETS & ACCESSORIES, KUP RELAYS
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.

Caution:
Sockets with .144” (3.66mm) and .184” (4.67mm) long solder
PCB/Solder terminals are available for KUEP, KUL, KUMP and KUP
relays,
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.

Screw terminal socket for relays through 3 poles 27E121
Screw terminal, DIN rail, snap-mount socket 27E893
Offers screw termination for KUEP, KUL, KUMP and KUP relays,
through 3 poles, with .187” (4.75mm) quick connect terminals. This
socket stacks on 1.700” (43.18mm) centers. When surface mounting,
two #6-32 screws of suitable length are required. When track
mounting, two 24A071 retainer clips (not shown) are required.
Offers screw termination for KUEP, KUL, KUMP and KUP
relays, through 3 poles, with .187” (4.75mm) quick connect
terminals. This socket is constructed with a spring-loaded
latch which allows it to be quickly snapped onto or removed
from a DIN or “top hat” style mounting track. No special
tools or extra hardware is required for installation.
