Bosch's PWG brake pedal travel sensor for hybrid and electric vehicles features contactless and thus entirely wear-free travel measurement using a magnetic field sensor as well as redundant signal recording. With the compact design of the two sensor components (magnetic field sensor and magnetic circuit), the unit can be integrated cost-effectively into existing vehicle environments. It offers two designs that support a variety of configurations. The PWG12 has the sensor and the magnetic circuit fitted separately. This variant offers the greatest flexibility during installation and can be used, for instance, to measure the stroke of the brake rod. The PWG13 has the magnetic circuit already integrated. This variant can be applied mechanically for, among other things, measuring pedal angle. Up to 45 mm (1.8 in) of stroke or up to 55° of rotation can be measured.
