DIMENSIONS HOW TO ORDER Types L, O, S, T and U terminal blocks are ordered by listing a composite number made up of the model designation followed by the number of terminals required for the application. Example: four-pole terminal block becomes stock number L-4, O-4, S-4, T-4 or U-4. When ordering combinations of both types, the composite number is made up of both model designations followed by total number of poles and number of each type. A composite of two T terminals followed by two U terminals thus is converted to stock number TU-4 (2T, 2U). Combining these types with Types L, O, S, H and BT would follow the same ordering format. (Note when combined with types H or BT a special adapter is required.) No. of Terminals Mounting Dimensions Inches (mm) Inches Overall Dimensions (mm) SERIES L SERIES O SERIES S SERIES T and U Dimensions shown are ± NOTE: Thru-bolt construction is amply strong for normal applications, but if excessive mechanical loads are expected, strain relief should be provided. Chart lists dimensions for up to sx terminals per block, but longer lengths are available. Tie-down points are recommended for blocks exceeding four terminals for Type U and six terminals for Type T. 37

36 * SNAP-IN SOCKET ASSEMBLIES CUS8 CUS12 RS11 Permanent-numbered terminals for easy identification. Compact, printed circuit design. 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. 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. 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 assemblies. 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 temperatures 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 vertical mounts or extreme vibration if end socket assembly is not mounted with screws. Available in three popular widths for maximum circuit design flexibility. TR1 for 2-3/16 PC board or socket. TR2 for 2-3/4 PC board or socket. TR3 for 3-1/4 PC board or socket. ORDERING INFORMATION Relay socket assemblies can be ordered in parts from (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; e.g. order RS8-17 for a track containing 17 RS8 relay socket assemblies. * Many Curtis Socket Assemblies are recognized under the components program of Underwriters Laboratories, Inc., under File No. E These units are marked with a on the following pages.
