Snap-In Socket Assemblies
Features:
? Permanent-numbered terminals for easy identification
? New unitized, thermoplastic sockets with closed-back design
which eliminates panel insulation, and resists breakage
? Nickel-plated screw-type terminals on break-resistant barrier-
type terminal block for fast, easy connection. Screw-type
terminals on other models with captivated wire clamps to
eliminate lugging.
Track
? Assemblies snap in and out without disturbing adjacent units
(except for dovetail design on CUS5, 12, 14, 15, and 16)
? Lengths up to 48" – holds up to 30 socket assembles
? Pre-punched track minimizes mounting time. (On lengths
of 48", drilling and tapping is only required for two or three
mounting screws instead of two holes per socket.)
? Wide center channel provides space for under-board
components. Allows greater surface area for easy mounting
with adhesive tape.
? Grey PVC thermoplastic, UL flame class 94V-0, suitable for
ambient termperatures up to 50° C.
? Vertical rib track provides support to prevent PC board
breakage—supplies spring retention and electrical base
insulation.
? Optional snap-on end retaining clips available for long
? Compact, printed circuit design
? Glass epoxy G-10 printed circuit boards
? Relay sockets can be spaced out in track for convenient
insertion of marking strips, for relay identification
? High-quality sockets for maximum relay retention and
electrical conductivity
? Available in three popular widths for maximum circuit design
flexibility.
TR1 for 2-3/16" board or socket
TR2 for 2-3/4" PC board or socket.
TR3 for 3-1/4" PC board or socket
HOW TO ORDER
Relay socket assemblies can be ordered in parts form
(assemblies and track separate) or factory assembled in
specific length units. When ordering factory assembled units,
specify type — number of sockets in continuous one-piece
precut track; for example, order RS8-17 for a track containing
17 RS8 relay socket assemblies.
