Removable knob exposes end of component shaft for precise phasing. Positive breaking action and large, highly readable numbers. Mounting Requirements: 1/4" shaft 3/4" 32-NEF-2A bushing. A high quality concentric scale dial designed to be used in conjunction with the 73JB multiturn potentiometer, the series 316 is available in clear brushed metal design or black anodized metal with white numerals at slightly higher cost. Price inducements are available when the 73JB and 316 dial are purchased together as a set. Readout and Operation: Unit shall register a total count of 15 turns. The number in the window (0-14) indicates completed number of turns of the drive sleeve. Graduated circular dial indicates the percent of a partial turn of the drive sleeve. Transfer Point: The number in center of window shall change as graduated dial rotates between 94 and 0. Rotation: Readout shall increase with clockwise and decrease with counterclockwise rotation. Brake Lever Operation: 1st Position (15 movement of Brake Lever) operates a high torque system for fine adjustment; 2nd Position (15 additional movement of Brake Lever) actuates brake. Accuracy: Backlash shall be zero between graduated dial and drive sleeve. Mounting: Install mounting bracket between panel and panel nut. Clarodial shall mount directly to shaft with No. 2-56 spline socket set screw, located adjacent to No. 50 on graduated dial. Numeral Size: 0.075 high. Graduation Size: Numeral graduations .045 long (1,14) intermediate graduations .030 long (0.76). Finish: Exposed metal partsBrushed metal finish; Turning knob and brake lever knobBlack plastic. Numerals: Graduated Dialblack; Turns Counterwhite on black background. Weight: 0.7 oz. max. (19.84 gm).

EACH 1272.53 11 2 Watt Wirewound Precision 10-Turn Potentiometers These 1 1/8" diameter, 2-watt OPick-A-ShaftO wirewound controls take a variety of shafts. These linear controls have 10% tolerance. They are economical but versatile in mounting, bushings and shafts. Effective rotation is 280 5 with 300 5 electrical rotation. Supplied without hardware. Switches, other shafts, other resistance values and other tolerances available as special order items. The 73 series is a 2-watt precision 10-turn potentiometer. The 73JB is the economical version of the 73JA, offering all the electrical features of the 73JA, but employing a long life nylon shaft construction. The 73JB has a metal bushing with glass filled black nylon shaft. The 73JA has a stainless steel shaft and metal bushing. Both shafts are 1/4" dia, 13/16 " long FMS and have 5/16" plain threaded bushing, screwdriver slots, and 50,000 cycles rotational life. End resistance is 0.3% of total resistance or 1 1/2, whichever is greater. 5% tolerance. 500 WV max. To complete stock number, see ohms chart below.
