MCA14

14mm carbon potentiometers with plastic enclosure and shaft. 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.

Through-hole configuration is 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 to hold the component to the PCB during soldering.

Tapers can be linear, log and antilog; special tapers can also be studied.

Applications:
– Electronic appliances: heating, temperature controls, ventilation, HVAC, thermostats, function selection.
– Measurement and test equipment.
