Spindle Operated Potentiometers Type LC1 Series Type LC1 Series Characteristics Electrical A very popular range is this 13mm Resistance Values and Law: Selection Tolerance: Rated Dissipation at 70°C: Limiting Element Voltage: Isolation Voltage: Electrical Rotation: Terminal Resistance: Noise (ENR): Insulation Resistance: Voltage Proof: 100R to 1M Linear ± 10% 1W 315V DC 450V DC 260° <50 Ohms 3% maximum >5 G Ohms 630V AC peak diameter spindle operated potentiometer family. The LC1 Series has a cermet resistance element. This technology provides excellent electrical and Characteristics Mechanical thermal stability, reliability, low noise and long life, to meet most professional or military applications for small size potentiometers. Recent changes have meant that the LC type is no longer released to BS CECC specification. Key Features ■ Rugged Terminations ■ Panel Sealed ■ Designed To Mil Standard ■ Proven Reliability ■ 1W Rating At 70°C ■ Low Noise ■ Cermet Element Starting Torque: Mechanical Torque: End Stop Torque: 5 - 20 mNm 295° ± 5° >225 mNm Characteristics Environmental Limits of Resistance Change: TCR (20°C to 70°C): Bump Severity: Vibration Severity: Climatic Category: Mechanical Endurance: ± 3% (after 1000 hours) <0.75% 390m/s2, 4000 Bumps 10 – 500Hz, 0.75mm or 98m/s2 55/125/56 25000 Operations minimum Dimensions Approvals The LC1 meets military specifications similar to MIL-R-94C style RV6 and MII-R-23285 style REC6.
