Series 72 Modular Potentiometer
Cermet or Conductive Plastic
|
|
|
| Description |
The Series 72 MODPOT modules are 5/8" square, stackable potentiometer and switch modules. Combine up to 2 sections, with plastic shaft and bushing (or bushingless). Vernier drive, plus rotary, push-pull and momentary switch modules are available.
Non-Magnetic when plastic shaft and bushing are used in combination with solder lug terminals.
