It can conveniently be used for minifying the instrument in which this model is employed. The construction of the Limit-Switch is given in the below figure and its function limit, either upper or lower, or to either side, can be freely determined according to customer's requirement. Its capacity is 5, 25V... (or 2.5, 25V...) This model is most recommended to all kinds of automatic control equipment. Note. Functioning position of Limit-Switch... In case of this model being coupled to servo-motor, an over-rotation of the servo-motor due to its inertia, after the power source being OFF, may sometimes break the Helicalohm Pot. unless an adequate precaution is made. In order to avoid such failure, two kinds of the Helicalohm Potentiometer with limit-switch are offered: one is an inscription type (a) Iimit-switch having its function position slightly this side from the stopper of Helicalohm Pot. and the other is a circumscription type (b) for which a special overtravel is prepared in the Helicalohm Pot. pprox. 45 SW Inscription Type (a) 36 n 2 pprox. 45 W direction SW 3 3 pprox. 3 SW ircumscription Type (b) 36 n 2 W direction pprox. 3 SW ± 3.5 ± L± 28 ± ± 3 2 SW SW3 M9 P.75 4 ± ±.2 N..: Unless otherwise specified, we will supply the circumscription type (b). Outer dimensions of these special versions are the same as those of standard model 46HD Series except its body length which is longer than the latter by 28 mm. Electrical and mechanical specifications and mounting dimensions are also the same as those of standard model 46HD series. s for smaller multi-turn potentiometer with limit-switches, please see page 47. 4

2 HELILOHM R MULTI-TURN POTENTIOMETER (Precision Multi-turn, Wirewound & Hybrid Element) There are two kinds in SKE Helicalohm Potentiometers with a wirewound resistive element. One is Model HD Series which are an original device consisting of a resistive element wound helically on a drum surface and a slider of which contact is made around the resistance drum and the other is Model HP Series which are formed with a slider travelling along the interior surface of a resistive element helically wound inside a sealed pipe. oth of them equally offer high resolution, excellent reliability and long life. SKE has expanded to the production of hybrid resistive element potentiometers and this element has now been incorporated into Model HP Series with small size. THE NOMENLTURE OF SKE HELILOHM POT. SERIES Special Specifications S means the potentiometer with special mechanical specifications not applicable to our standard. S 46 HD S - L G - Diameter 46 means the approximate outer diameter of the potentiometer in metric system. The 8 standard diameters are available, namely, mm, 2mm, 2mm, 22mm, 25mm, 3mm, 46mm and 5mm. 4 digits branch number to be used for specific requirements. Number of Gangs G means 2 ganged potentiometer on the same axle. The potentiometer consists of one single section unless G is given.(e.g. G ganged, G4...4 ganged.) pplication L means for semi-fixed purpose. P means for p.c. terminals. W means for lug terminals at rear end. S means shortened body type (only for use on 2HP-ns). E means inch dimensional bushing and shaft type. Type and Internal onstruction H means helicalohm, multi-turn, linear potentiometer. There are 4 kinds of HP, HHP, HD and HDS. HP, HP... Wirewound type with resistive element helically wound inside the pipe-shaped housing. HHP... Hybrid type with same construction as HP type. HD... Wirewound type with resistive element helically wound on the drum-shaped base. HDS... Super-precision type with same construction as HD type. SELETION GUIDE Number of Turns means -turn. There are 5 kinds in the number of our standard multi-turn potentiometers. They are 3, 5,, 5 and 2, but subject to models. Mounting Method S means servomount type(in case of bushingmount type, S is deleted.)

Slide wire resistive element type which brings infinite resolution is available as standard version against the standard resistance values below 2Ω in this series, but subject to models. This series has the highest performances, especially in resolution and in linearity tolerance, which are almost at the upper practical limits in wirewound type pot. You can also use this pot. as a standard potentiometer. 29

It can conveniently be used for minifying the instrument in which this model is employed. The construction of the Limit-Switch is given in the below figure and its function limit, either upper or lower, or to either side, can be freely determined according to customer's requirement. Its capacity is 5, 25V... (or 2.5, 25V...) This model is most recommended to all kinds of automatic control equipment. Note. Functioning position of Limit-Switch... In case of this model being coupled to servo-motor, an over-rotation of the servo-motor due to its inertia, after the power source being OFF, may sometimes break the Helicalohm Pot. unless an adequate precaution is made. In order to avoid such failure, two kinds of the Helicalohm Potentiometer with limit-switch are offered: one is an inscription type (a) Iimit-switch having its function position slightly this side from the stopper of Helicalohm Pot. and the other is a circumscription type (b) for which a special overtravel is prepared in the Helicalohm Pot. pprox. 45 SW Inscription Type (a) 36 n 2 pprox. 45 W direction SW 3 3 pprox. 3 SW ircumscription Type (b) 36 n 2 W direction pprox. 3 SW ± 3.5 ± L± 28 ± ± 3 2 SW SW3 M9 P.75 4 ± ±.2 N..: Unless otherwise specified, we will supply the circumscription type (b). Outer dimensions of these special versions are the same as those of standard model 46HD Series except its body length which is longer than the latter by 28 mm. Electrical and mechanical specifications and mounting dimensions are also the same as those of standard model 46HD series. s for smaller multi-turn potentiometer with limit-switches, please see page 47. 4
