OCP10 10mm OPEN CARBON PRESET QUICK REFERENCE DATA Resistance range (E3-series}, linear law 47 0-4,7 MQ Maximum dissipation at 40 C 0,1 W Climatic category, IEC 68 25/070/71 APPLICATION These potentiometers are for preset resistance control with provision for re-adjustment. They are particularly suitable for use in radio and television receivers. DESCRIPTION These potentiometers have a resistance element of a special carbon composition with a low temperature coefficient. The element is riveted to a base plate of resin bonded paper. The potentiometers are provided with printing-wiring pins; pins a and c (see drawings) are connected to the ends of the carbon track, pin bis connected to the wiper. The wiper, which is provided with a double contact, has a screwdriver slot or a plastic knob for adjustment. This potentiometer series includes types for vertical and for horizontal mounting on printed-wiring boards, The resistance law is linear and the tolerance on the nominal resistance is 20%, however log, versions and 10% tolerance versions are also available, * Note: The potentiometers are supplied with the wiper positioned at 50% of the angle of rotation. oT b 7285818 February 1990 199OCP10 COMPOSITION OF THE CATALOGUE NUMBER S i i flat knob Type 1 for versions 2322 410 411 412 433 434 450 6 = flat knob Type 2? for versions 2327 410 611 612 633 634 without knob 2322 410..... | code for __ resistance value f see Table 7 11 = vertical mounting straight pins longitudinal slot raised version 12 = vertical mounting snap-in pins lengitudinal slot raised version 13 = vertical mounting snap-in pins cross slot raised version 14 = vertical mounting straight pins cross slat raised version 15 = vertical mounting straight pins cross slot normal version 33 = horizontal mounting straight pins longitudinal slot 34 = horizontal mounting snap-in pins longitudinal slot 35 = horizontal mounting snap-in pins cross slat 36 = horizontal mounting plug-in pins cross slot 50 = vertical mounting plug in type longitudinal slot normal version Note: catalogue number of knob type 1 (Figs 4,5, 9): 4322 047 00190: catalogue number of knob type 2 (Figs 6, 10): 4322 047 27740, MARKING The potentiometers are marked with the nominal resistance value punched on the wiper. 200 February 199010 mm open carbon preset OCP10 Outlines 2.59 max "| ato2 ue? 2 - et O9 F005 I FRE PRS a= 220.05 - 0402 = 2322 410 050 2322 410015 lang slot eross slot Fig.1 Potentiometers for vertical mounting; straight pins. 3,9 max ~ 08k oe ==0.9 60.05 2 = ~ $0402 -- AZM + ? | 28 2322 410011 = tong slot i 2oe2 410014 = cross slot Fig.2 Potentiometers for vertical mounting: straight pins (raised version). : (rm 1990 201OCP10 23 max = | = +02 0.2 area 20.05 e le OF the ] 25 o | o ue ot | e-25 f | * 2322 410 012 = tong slot oe 2322 410013 = cross slot Fig.3 Potentiometers for vertical mounting: snap-in pins {raised version), iptOS_. 4 U 0 | MJ syreesas e454 0.9 Fig.4 Potentiometers for vertical mounting, with knob type 1: straight pins, 2322 410 450, 202 February 199010 mm apen carbon preset OCP10 2322 410411 = straight pins 2322 410412 = snap-in pins Fig.5 Potentiometers for vertical mounting, with knob type 1: (raised version}. =| | = P| - | a | 14402 = to EE a LL 1,3 01 a . 4 = 3,2 lect 1a =o eaEESF 2322 410 611 = straight pins 2ae2 410 612 shap-in pins Fig.6 Potentiometers for vertical mounting, with knob type 2: (raised version).
