Variohm’s new low cost linear position sensor is based on sealed membrane potentiometer

The new IPL series linear sensors are available in nine standard position or displacement measurement ranges with independent linearity to +/- 3% and average repeatability to +/- 0.5 mm. For higher precision use, a membrane potentiometer with independent linearity to 1% is available on request.

Aimed at demanding linear measurement applications across all industries, they are particularly well-matched to door and gate closures, valves and vents, lifting and handling machinery, and other areas where low-cost position verification is essential. The simple design of the IPL can be manually driven with minimal force required, or provide position feedback in combination with electric, pneumatic or hydraulic automated actuators.

The field proven IP65 rated membrane potentiometer and the durable anodised aluminium frame and plastic wiper mechanism is capable of operation in harsh environments. The temperature range for the assembly is -40 to +85ºC with humidity at 95% RH.

The flexibility built into the range includes standard Crimpflex solder-tab electrical terminations and further connector options on request. Thanks to Variohm’s own in-house design and manufacturing capability, the IPL linear position sensor can be supplied in custom measurement lengths and the mechanical interface can be application adapted for OEM customers.
