Description
The P cermet potentiometers („potențiometre cermet simple”) are single cermet potentiometers, P-34534 without and P-34533 with a 1 A / 250 V switch, made to STAS 9614/2-74 for professional electronic circuits: 100 Ω to 2.5 MΩ, ±30 %, rated 1 W at 40 °C and 250 V [1].
The Agenda radioelectronistului names IPEE Electro-Argeș of Curtea de Argeș and IIS Electronica of Bucharest as the producers of the potentiometers in its section on potentiometers made in Romania, in both editions, without saying which works made which type; they are listed here under Electronica [3][4]. Electronica românească. O istorie trăită, vol. I, says that Electronica imported in 1969 a production line for film potentiometers from Siemens (West Germany), and that it made single potentiometers with or without a mains switch, tandem and push-button potentiometers, defined by its internal norm NID 2195-67 [5].
The book does not explain the codes [1]. The 1st edition (1983) gives the same data [2].
Rated power at 40 °C. Dimensions in mm (fig. 17.2): shaft length L = 12, 16, 20, 25 or 32, threaded bush M7 × 0.75, body Ø 16.2 [1].
