Data Sheet

9mm carbon potentiometers 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 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.
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 20 detents available).
- Self-extinguishable plastic parts according to UL 94 V-0.
Applications
9mm potentiometers are mainly used in control applications, in
different markets:
- Industrial: Timers and relays, dimmers, adjustment of output.
- Electronic appliances: volume regulation, temperature controls and
function selection.
- Automotive: Lighting regulation (position adjustment and sensing
for headlights), dimmers, seat heating controls.
9mm cermet potentiometers 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 (housing and rotor) are self-extinguishable according to
UL 94 V-0 for ACP’s cermet potentiometers.
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.
Tapers can be linear, log and antilog; special tapers can also be
studied.

Applications
9mm cermet potentiometers are used in applications where either
the operating temperature is high, or where the application requires
product with excellent ohmic value stability:
- Electronic appliances: temperature controls.
- A
utomotive: climate controls, position sensors, seat heating controls.
- Industrial electronics: multimeters, oscilloscopes, time relays,
measurement and test equipment.
