CA9

CARBON potentiometers in 9mm (CA9) with 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.

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 to hold 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.

Applications:
– Industrial: Timers, Safety Relays, Power Supplies, Multichanel Circuit Breakers, Dimmers…
– Electronic appliances: volume regulation, temperature controls and function selection.
– Building Automation: IR sensors, PIR sensors, Alarm Systems, Antena Amplifiers, Videocomm, intercomm…
– Automotive: Lighting regulation, dimmers, seat heating controls.
– Measurement and test equipment.
