Rotary position sensor suits harsh environments
A
Variohm Eurosensor product story
Edited by the Engineeringtalk editorial team
Oct 21, 2009
Variohm Eurosensor has launched a rotary position sensor for price-sensitive industrial and automotive applications in harsh and extended-temperature-range environments.
The SP5000 from Novotechnik 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.
The SP5000 rotary position sensor is aimed at all types of harsh environments including close proximity to high-vibration/high-temperature sources such as engines in automotive applications
Built for maximum durability with a vibration rating to 20G, the long-service-life sensor uses O-ring sealed/plug-in shaft mounting with brass-bushed flange fixing holes, as well as an integral Amp three-pin junior timer connector for straightforward installation.
The heavy-duty SP5000 series is targeted at all types of harsh environments, including situations in close proximity to high-vibration/high-temperature sources such as engines in automotive applications.
The specification includes a working temperature range of -40 to +125 degrees with a short-term extended-temperature rating to +150 degrees.
Its working life is four million movements with an operating speed up to 100rev/min.
The electrical characteristics include repeatability to one per cent and an independent linearity of less than two per cent.
Novotechnik's conductive plastic wiper technology has been applied to large-volume industrial and automotive applications that require high reliability at extended-temperature ranges and maximum resistance to harsh, high-vibration environments.
For a long life and total measurement reliability, these conductive plastic resistance elements are built up in multiple printed layers using Novotechnik's 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,.
The SP5000 series is part of a range of contacting and non-contacting angular position sensors available from Novotechnik, stocked and fully supported in the UK and Ireland by Variohm Eurosensor.
