Novotechnik SP5000 rotary position sensor for harsh environments

Variohm-EuroSensor is introducing the Novotechnik SP5000 rotary position sensor that is suited to price-sensitive industrial and automotive applications for harsh and extended temperature range environments.

The SP5000 uses field-proven conductive plastic technology in a compact, IP67-rated, high-grade plastic housing and is available in a choice of 104-, 117- and 120-degree electrical angles. Built for maximum durability with a vibration rating to 20 'g' the sensor uses O-ring sealed/plug-in shaft mounting with brass-bushed flange fixing holes plus an integral AMP three-pin Junior Timer connector for straightforward installation.

Variohm says the SP5000 series sensors are aimed at applications in all types of harsh environment, including close proximity to sources of high vibration or high temperature - such as engines in automotive applications. The impressive specification includes a working temperature range of -40 to +125 degrees with a short-term extended temperature rating of +150 degrees. Its working life is 4million movements with an operating speed up to 100rpm. The electrical characteristics include repeatability to 1 per cent and independent linearity of less than 2 per cent.

Low-cost, high-reliability technology

Novotechnik's highly developed conductive plastic wiper technology has been applied extensively to large-volume industrial and automotive applications where fundamental requirements include high reliability at extended temperature ranges and maximum resistance to harsh, high-vibration environments. The technology is often preferred to non-contact position sensors because its design simplicity, wide temperature range and environmental durability maintain an attractive price/performance ratio.

For exceptionally long life and reliability, these conductive plastic resistance elements are built up in multiple printed layers using Novotechnik's own specialised conductive inks; multi-fingered precious metal wipers, arranged within an elastomer damping mechanism, maintain complete contact - even under arduous working conditions.

The technology is available for both rotary and linear position measurement in a number of mounting styles and grades of precision, including dual-redundancy versions, with customisation readily available to suit specialised applications.

Novotechnik's SP5000 series is part of a wide range of contacting and non-contacting angular position sensors available that are stocked and fully supported in the UK and Ireland by Variohm-EuroSensor.
