Hall effect linear position sensor for extreme motorsport environments

By DA Staff / 08 Jan 2011

Penny + Giles has launched a new sealed linear contactless sensor for the motorsport market, the SLH100. The robust sensor has been designed to provide cost-effective precision position sensing using the proven contactless Hall effect principle. This ensures reliable and accurate measurement in extreme motorsport environments.

Unlike potentiometers, SLH100 can operate in high dither vibration conditions with no deterioration to the sensing element. Being contactless, it is attractive for use in harsh environments where particles, moisture, high temperature and vibration can be present and as a result it offers maximum performance in a variety of racing vehicles, including single-seat cars, sports cars, touring cars and motorbikes.

The ultra-compact sensing system comprises two parts – the sensor and the magnetic activator. The sensor is offered with a 28mm measuring range and it has an operating temperature of –40 to +125 degrees C.

SLH100 is a fully encapsulated electronic device that operates from a 5Vdc regulated or 8-30Vdc unregulated power supply and it features an on-board micro controller that linearises the Hall sensor output to better than 1% over the 28mm total range.

The sensor has a virtually infinite life and provides a highly reliable solution for absolute position sensing problems. It is maintenance-free and is easy to fit – it is simply screwed in to place with two M3 screws.

The linear Hall effect sensor is the latest in the range of Hall effect sensors from Penny + Giles which includes the popular SRH280 rotary sensor. All products are manufactured at Penny + Giles’ ISO9001 certified facility.
