R10 Socket & Accessory Information
Socket Specifications
Contact Material:
Body Material: 2 and 4 pole: polyester.
Voltage Drop: 30mV max. @ 10A.
Dielectric Strength: 1,000V rms.
Insulation Resistance: 10
Max. Current: 10A.
Solder or PC Terminal Sockets
Rugged, molded socket body retains floating
terminals of either solder or printed circuit pin
configuration. PC terminal sockets are offered
with pins in either 0.1” (2.54mm) grid or in-line
arrangement.
Grounding Provisions
Pre-installed on sockets
Not for use at 5A AC and above.
Grounding Strip: Mounting stud of relay
contacts grounding strip. Grounding strip is
grounded with screw or rivet through round hole
in socket.
Grounding Terminal (PC sockets only):
Mounting stud of relay contacts ground terminal
through square hole in socket.
Strip
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.
Spring brass, tin-plated.
