Stand No. E418, Hall 19
Autosport International, Birmingham, UK
10-11 January 2008
Hall effect position sensors for extreme motorsport environments
Penny
+ Giles will be exhibiting its new sealed linear contactless sensor for
the motorsport market, the SLH100, at Autosport International, stand E418.
Also on display will be the company’s popular range of non-contact
SRH280 sealed rotary sensors, which will shortly include a new version that
operates from a low 5Vdc regulated supply and will also have programmable
features.
The robust sensors are 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 and SRH280 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 SLH100 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 SRH280 features a 12-bit processor and offers 0.088° measurement
resolution for high precision monitoring. The 28mm diameter sensor is sealed
to IP50 or IP68 and is available with analogue voltage or pulse width modulated
digital signal output.
For further information about the company’s wide range of linear and
rotary sensors, and a demonstration of the products, visit stand E418 at
Autosport International.
