Rotary potentiometer handles heavy and light jobs

The multipurpose design of the P270 rotary potentiometer suits use in heavy-duty equipment as well as light panel applications

BI Technologies Electronics Components Division's P270 27mm rotary potentiometer has been specified for use by manufacturers in industrial, commercial, audio and heavy equipment markets.

"The multipurpose design of the P270 device lends itself for use in heavy-duty equipment as well as light panel applications", said Alain Leon, Variable Products Applications Engineer for BI Technologies.

"With the extended life cycle to 1 million rotations and multiple design options including package sealing and centre-tap and two gangs for redundancy, the potentiometer is suitable for applications ranging from electric guitars to industrial lifts".

The P270 potentiometer has been used in industrial scissor lifts to raise and lower platforms and heavy duty welders, as well as custom-built scooter controls with special short angle and sealing elements to protect against harsh environments.

It has also been used in throttle assemblies in vehicles, and directional speed controls for forklifts and material handling equipment.

The P270 has a resistance range of 1Kohm to 1Mohm and standard tolerance to +/-10%.

Power ratings are 2W at 70C, with a maximum input voltage of 500V DC and di-electric strength of 1000V AC.

The operating temperature range is -55 to +120C.
