MCA14 – MCE14

14mm carbon potentiometers with plastic enclosure and shaft.
Through-hole and SMD configurations are available. Terminals and collector are normally manufactured in tinned brass, although versions with steel terminals are also available under request. Terminals for through-hole models can be provided straight or crimped, which helps hold the component to the PCB during soldering.
Ingress Protection rating type IP 54 (high level of protection against dust and also against water splashing), according to IEC 60529.
Plastic materials can be self-extinguishable according to UL 94 V-0 under request.
Tapers can be linear, log and antilog; special tapers can also be studied.
Potentiometers can be manufactured in a wide range of possibilities regarding:
- Resistance value.
- Tolerance.
- Tapers / variation laws.
- Pitch.
- Positioning of the wiper (standard is at 50% rotation).
- Housing and rotor color.
- Mechanical life.
- Click effect (up to 38 detents available).
- Self-extinguishable plastic parts according to UL 94 V-0.
Applications
14mm potentiometers are mainly used in control applications, in different markets:
- Electronic household appliances, heating, ventilation and air conditioning (HVAC) equipment, thermostats.

14mm cermet potentiometers with plastic enclosure and shaft.
Cermet potentiometers have better thermal stability, allow for higher thermal dissipation and withstand higher temperatures than carbon potentiometers.
Through-hole and SMD configurations are available. Terminals and collector are manufactured in tinned brass, although versions with steel terminals are also available under request. Terminals for through-hole models can be provided straight or crimped, which helps hold the component to the PCB during soldering.
Ingress Protection rating type IP 54 (high level of protection against dust and also against water splashing), according to IEC 60529.
Plastic materials (housing and rotor) are self-extinguishable according to UL 94 V-0 for ACP’s cermet potentiometers.
Tapers can be linear, log and antilog; special tapers can also be studied.
Potentiometers can be manufactured in a wide range of possibilities regarding:
- Resistance value.
- Tolerance.
- Tapers / variation laws.
- Pitch.
- Positioning of the wiper (the standard is at 50%).
- Housing and rotor color.
- Mechanical life.
- Click effect (up to 38 detents available).
Applications
14mm cermet potentiometers are used in applications where either the operating temperature is high, or where the applications requires product with excellent ohmic value stability:
- Electronic appliances: boilers, water heaters.
- Industrial electronics: multimeters, oscilloscopes, time relays, measurement and test equipment.
