Brake master cylinder position sensors

The master cylinder converts the motion of the brake pedal into a hydraulic pressure that is used to operate brake caliper movement. It consists of the reservoir, which contains the brake fluid, and the piston and cylinder that generate the hydraulic pressure. Traditionally, racecars use two master cylinders that are side by side being applied at the same time (dual). This creates two separate hydraulic braking circuits. If one of the circuits becomes inoperative, the other circuit can still function to stop the racecar. Race engineers monitor master cylinder movement during racing to assist the driver in making brake balance adjustment based on car performance in ever-changing tyre and track conditions.

For bespoke applications we offer a comprehensive design, manufacture and speedy delivery service to satisfy the fast paced engineering developments associated with international motorsport.

Linear potentiometers - general purpose, high performance

Both the SLS and MLS Series of linear potentiometers are designed using the proven benefits of composite track technology and include a number of design features. The SLS has a single track suitable for general applications, where performance and reliability coupled with competitive pricing is of importance. The MLS has a twin element conductive track design which provides superior performance under vibration and shock conditions. They are available with a range of case diameters and stroke lengths up to 500mm (20").

Magnetic hall contactless linear position sensors

Magnetic hall contactless position sensors are based on true solid-state 'hall-voltage/magnetic-field' measurement technology. Sensor designs are available with single or dual outputs and design benefits, include improved output signal linearization over the measurement range, overall sensor accuracy and higher operating temperatures compared to similar position sensor products.
