New Yorker Electronics has announced the availability of the new Vishay Sfernice P11H series of modular high torque panel potentiometers. According to Vishay, they deliver an industry-high rotational torque of 8 newton-centimeter (Ncm), a full 200% higher than the closest competing device — in a compact 12.5 mm size with a 6.35 mm shaft diameter.
Vishay Sfernice P11H modular high torque panel potentiometers are designed to keep the setting when under high mechanical constraints from vibration, shock and other factors. The new series provides high torque with smooth operation throughout the life of the potentiometer. The P11H series is available in tolerances of ±10% or ±20% and in resistance options of 1 kΩ, 4.7 kΩ, 10 kΩ, 47 kΩ and 100 kΩ. The operating temperature range is between -55° C and 125° C.
Approved by CECC 41000 and IEC 60393-1 with a seal rating of IP64, the series operates over a lifespan of 50,000 cycles. Device options include custom shafts, switches, connectors, wires and special leads and tapers. Applications for the modular high torque panel potentiometers include voltage dividers or rheostats for light, radio volume and air conditioning control in tractors, construction equipment and aircraft cockpits plus industrial tool settings and electric welding, motor speed and low power controls.
The W10 PCB pin mount lead is 35.6 mm (1.40 in) long; the Y00 solder lug (wire mount) lead option is 30 mm (1.18 in) long. Both are for vertical mounting but PCB pin horizontal mounting is easily customizable. Other device options include custom shafts, switches, connectors, wires and special leads and tapers.
