Return PC16BU POTENTIOMETER P16 MECHANICAL SPECIFICATION Operating Torque: 0.4 - 1.5 Ncm Permissable Axial Spindle Load: 50 N (5 Sec. maximum) Permissable Torque at End Stop: 35 Ncm Rotation angle, without a switch: 270° ±5° Rotation angle, with a switch: 300° ±5° Click Stop facility available on certain models ELECTRICAL SPECIFICATION Tolerance on Rated Resistance: ± 20% Option ± 10% Effective rotation Without a switch: 267° nominal. With rotary switch: 232° nominal Rated Power Dissipation @40°C 0.25W linear law, 0.12W non linear law Rated Resistance: E3 Series, Optional: E6 Series Linear Law: 1K - 1M Non linear Law: 4K7 - 470K Law; Lin (a) Log (B) Antilog (C) Operating Temperature: -25°C to +70°C P16 BUSH OPTIONS The P16 bushes are available in metal or nylon; with an M7 or M10 thread; and with or without a locating feature: Diecast Zinc Alloy M10 x0.75mm pitch (Type C) M7 x0.75mm pitch (Type CG) M7 x0.75mm pitch, with locator (Type CEP) Glass Filled Nylon M10 x0.75mm pitch (Type CP) Do not attempt to prevent any unwanted body rotation by overtightening the retaining nut, since this can cause thread damage, distortion, change of electrical resistance and restrict shaft rotation. BS9130:1972 provides further details on this topic. The recommended torque for tightening the retaining nut is 45cNm and this can be achieved cost effectively by using a Torque Limiting device as shown on our Accessories page. P16 SPINDLE OPTIONS The P16 spindles are plastic, unless otherwise stated, fixed i.e. not removable and they are available in three diameters: 6.0mm Diameter Cylindrical (Type F1) 4.0 x 12mm Flat (Type F2) 5.0 x 15mm Flat (Type F3) 5.0 x 10mm Flat (Type F4) 4.6mm x 15mm Flat (Type F11) 4.0mm Diameter 3.0 x 8.5mm Flat (Type F22) 3.0 x 8.5mm Flat (Type M22 - Metal) 6.35mm Diameter Cylindrical (Type F41) 5.5 x10mm Flat (Type F42) 5.5 x 15mm Flat (Type F43) Splined Spindle - 6.0mm dia. 18 teeth Dual Concentric Flatted/Slotted (Type M15 - Metal) Cylindrical (Type M16 - Metal) 6.0mm Diameter Spindles Note: *Specials to customer's specification up to 65mm. 4.0mm Diameter Spindles Note: The orientation of the flat as illustrated is for plastic spindles only. For metal spindles, unless specified on the order, the orientation may be different on each potentiometer type. 6.35mm Diameter Spindles Note: *Specials to customer's specification up to 65mm. Splined Spindle - 6.0mm dia. 18 teeth A splined form is available on the 6.0mm diameter P16 plastic spindle (F5) or alternatively a 6mm 'Splined Adaptor' (8.7mm long) can be fitted on a 4mm dia. Spindle (F5A): Dual Concentric Spindles
