Fullerton, Calif. TT electronics BI Technologies Electronic Components Division has developed a 27-mm rotary potentiometer for panel-mount configurations. The Model P270 rotary potentiometer features a life cycle of up to 1 million rotations.
The Model P270 conductive plastic potentiometer features a resistance range of 1 Kohm (KΩ) to 1 MΩ and standard tolerance to ±10%. Power ratings are 2 W at 70°C, with a maximum input voltage of 500 Vdc and dielectric strength of 1000 Vac. The operating temperature range is -55°C to 120°C. Custom specifications are available. The series is RoHS compliant.
The Model P270 panel potentiometers are offered with a dust proof option, as well as full seal, center tap, and dual gangs. Availability of an optional sealed package make the device suitable for industrial applications and its robust design allows it to be used in heavy-duty applications, said the company. Applications include joystick controllers for handicap power chairs and aerial lifts, industrial motor speed controllers, industrial welder power controllers, industrial foot switches and pedals, directional speed controllers for forklifts, and hydraulic valve controllers for heavy equipment.
Pricing: Typical pricing for a standard Model P270 rotary potentiometer is $4.00 to $6.00.
Availability: Lead times are from stock to five weeks.
