Meggitt Citec Panel Potentiometers 153 sealed military style Key features cermet or co-moulded carbon • proven reliability • mcu widely stocked • 2 watts at 70°C (in cermet) • sealed to military standard • type M series panel and container sealed (mc1, mh1) • rugged terminations • strong construction • Electrical Type: Element Technology: Resistance Range: resistance elements. This choice means that components offer excellent electrical and thermal stablity, reliability, low noise and Specification long life which makes them highly suitable for the majority MCU MC1 Cermet 100R ~ 1M (Linear) --1, 2.2, 4.7 ±20% 2 W (Linear) Cermet 10R ~ 1M (Linear) --1, 2.2, 4.7 ±20% 2 W (Linear) Limiting Element Voltage: Electrical Rotation: Voltage Proof: MH1 Co-Moulded Carbon 100R ~ 2M2 (Linear) 1K ~ 2M2 (Log) 1, 2.2, 4.7 ±20% 0.25W (Linear) 0.125W (Log) 250VDC 260° 500V AC peak 315VDC 210° 630V AC peak 315VDC 210° 630V AC peak Mechanical End Stop Torque: Starting Torque: Mechanical Adjustment: 800mN m <85 mNm 300° 800mN m <85 mNm 300° 800mN m <40 mNm 300° Environmental Limits of Resistance Change: Rotational Life: Sealing: 15% (after 1000 hours) 25000 cycles min. Panel 3% (after 1000 hours) 25000 cycles min. Panel 3% (after 1000 hours) 25000 cycles min. Fully Enclosed Resistance Values: Resistance Tolerance: Power Rating at 70°C: A most popular range available with cermet or co-moulded of professional applications. The MC1 Series is used in the Tornado Project and is the standard single turn general purpose panel control used for most military applications in the UK and Europe.
