CER14

This product family was born as an alternative to the CE14 series when curved designs appear. The upper corners of the
housing has been modified in order to set the product properly.

CERMET potentiometers in 14mm(CER14) with the plastic housing and 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.

Cermet potentiometers have better thermal stability, allow for higher thermal dissipation and withstand higher temperatures than carbon potentiometers.

Through-hole configuration is available; for SMD version, please, inquire. Terminals and collector are manufactured in tinned brass. Terminals for through-hole models can be provided straight or crimped, which helps tohold the component to the PCB during soldering.

Tapers can be linear, log and antilog; special tapers can also be studied. ACP’s potentiometers can be adjusted from either the front or the back, both in the horizontal and the vertical adjustment types. Thumbwheels and shafts can be ordered either separately or already inserted in the potentiometer.

CER14 is used in applications where either the operating temperature is high, or where the applications requires product with excellent ohmic value stability

– Industrial: motor speed regulation, thermostats.
– Electronic appliances: temperature controls, function selection.
– Building Automation: ventilation, air conditioning, heating
– Automotive: HVAC controls, Lighting regulation, dimmers, seat heating controls.
– Measurement and test equipment.
