| Series 270 (R) Commercial Miniature 5/8" (16mm) Diameter Composition Variable Resistors * Miniature 5/8" (16mm) size * Versatile mounting styles: - bushing - twist tab - bend tab - snap-in PC bracket - solder lug or PC terminals (shaft parallel or perpendicular to the panel) * 100 to 5 Meg resistance range * Molded or metal shafts * SPST power switches * Single, tandem, or concentric units * Panel seal * Rear extended shaft Electrical and Mechanical Specifications Resistance Range 100 through 5 Meg (linear taper). Resistance Tolerance Standard: 20% Special: Other tolerances available in most resistance values. Power Rating, Watts 1/4 watt per section through 100K 1/5 watt per section above 100K Full rating @ 55C derated to no load at 85C, linear taper, bushing mounted control on steel panel 4" x 4" x .050" (101.6mm x 101.6mm x 1.27mm). (Derating required on two section controls.) Voltage Rating Bushings to Terminals: High pot test, one minute -- 750 VAC Operating maximum -- 500 VDC Across End Terminals: 350 VDC, load not to exceed listed wattage ratings. Resistance Tapers Standard: Linear, 10% Audio and 10% CCW Audio Special tapers available to meet most requirements Angle of Rotation Total Rotation Without Switch: 300 5 With Switch: 315 5 Effective Rotation Without Switch: 300 (approximate) With Switch: 290 (approximate) Panel Mounting Information Bushing Mount Standard: Brass (continued on next page) Technical Data Sheet 1448C Technical Data Sheet 1270E CTS CORPORATION / MANUFACTURER OF RELIABLE ELECTRONIC COMPONENTS Electrical and Mechanical Specifications (continued) All Other Mounts Standard: Twist tab (designated by "1") Special: Bend tab -- 2 or 3 ears Bracket mounted Suggested Panel for Twist Tab .042" thick (1.07mm) Locating Lugs (Bushing Mount) Standard: .312" (7.9mm) radius from center of control. Special: .375" (9.53mm) radius from center of control. Standard Position: Left side supplied unless otherwise specified. Other Positions: Available with lug right side, without lugs, or with lugs both left and right sides. Water Seal Construction Controls are also available to prevent water from entering the control through either the O.D. of shaft and/or the bushing. Concentric Tandem Units Available in two combinations: A - .125" (3.2mm) diameter rear shaft .250" (6.35mm) panel shaft (3/8 - 32 or M9X.75) B - .156" (4.0mm) diameter rear shaft .236" (6.0mm) diameter panel shaft (3/8 - 32 or M8X.75) Most metal shaft diameters can be used with twist tab mountings. With bracket mount, only .187 diameter shafts are used, with turn-down available to obtain smaller diameters. Metal Lengths: Minimum .125" (3.2mm) beyond bushing; special lengths as required. Trims: Plain round screwdriver slotted, flatted, knurled. Other trims available upon request. Molded Flatted and knurled with screwdriver slot available in many lengths and diameters. Terminal Information Standard: T Solder lug formed 90 to the rear. Special: (See below) T: T: U: Solder lug perpendicular to shaft. Solder lug formed 60 to the rear. PC terminals formed 90 forward toward mounting surface. Terminals extend .187" (4.7mm) beyond mounting surface. PC terminals formed 90 to the rear, away from panel mounting. Terminals extend .520" (13.2mm) from mounting surface.
