New P30L Panel Potentiometer

The Key Benefits:

• Offers a long life of 1 million cycles
  • Increases reliability and lowers maintenance costs
• Features a fully sealed, compact IP67 package with pure Sn terminals
• With only a 19.7-mm diameter, it offers designers a compact alternative to other
  2-W panel potentiometers
• Provides a low temperature coefficient down to ±150 ppm/°C
• Offers high 2-W power rating at 70 °C and high maximum operating torque of
  4.25 oz. per inch
• An operating temperature range of - 40 °C to +100 °C ensures reliable operation even in extreme environments

The Key Applications:

• Industrial control panel, heavy-duty control, automotive and off-road control, and harsh environment applications in end products including trucks and tractors, machine tools, HVAC systems, welding machines, and military, agricultural, and water-resistant equipment

New Vishay Sfernice P30L Panel Potentiometer Features Long Life of 1 Million Cycles, Low Temperature Coefficient Down to ±150 ppm/°C, and High 2-W Power Rating at 70 °C in Compact, Fully Sealed IP67 Package

Vishay Intertechnology, Inc. (NYSE: VSH) announces a new long-life, compact panel potentiometer with a high 2-W power rating, low temperature coefficient, and high operating torque.

• Its cermet element provides better stability than carbon elements, while its 2500-VRMS dielectric strength offers greater reliability and robustness
• Features four resistances values from 1 kΩ to 50 kΩ over a 44.7-V to 300-V working range
• Low 3 % typical contact resistance variation
• Custom shafts are available in accordance to drawings supplied by customers

Key Device Specifications:

• Life: 1 million cycles
• Temperature coefficient down to ±150 ppm/°C
• 2-W Power rating at 70 °C
• IP67 package
  • 19.7-mm diameter
• Maximum operating torque: 4.25 oz. per inch
• End stop torque: 99 oz. per inch
• Four resistances values from 1 kΩ to 50 kΩ
• 44.7-V to 300-V working range
• 3 % typical contact resistance variation
• Operating temperature range: - 40 °C to +100 °C

The Perspective:

While standard panel potentiometers reach 100,000 cycles, the new Vishay Sfernice P30L offers a long life of 1 million cycles. For designers, this reduces the need for replacement parts, increasing reliability and lowering maintenance costs.

Availability:

Samples of the P30L are available now. Production quantities will be available in Jan. 2008, with lead times of eight to 10 weeks for larger orders.
