Data Sheet

9mm 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 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 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 20 detents available).
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.
- Automotive: climate controls, position sensors, seat heating controls.
- Industrial electronics: multimeters, oscilloscopes, time relays,
measurement and test equipment.
