Displacement sensors withstand automotive rigours

For demanding automotive applications, Tyco Electronics has designed a range of permanent magnetic linear contactless displacement (PLCD) platform sensors.

For demanding automotive applications, Tyco Electronics has designed a range of permanent magnetic linear contactless displacement (PLCD) platform sensors.

PLCD sensors are ideally suited for contactless travel and angle measurement and can measure distances up to 200mm with either analogue or digital interface.

PLCD sensors are used for numerous automotive applications such as linear drive mode sensors in automatic transmissions and gear, shift and neutral position detection as well as clutch position measurement in automated manual transmissions.

Furthermore the devices are used as clutch position sensors in electrical park brakes and in distribution-boxes for 4x4 vehicles.

PLCD sensors provide accurate measurement performance and are resistant to high vibration and variable temperature environments.

A permanent magnet, located on the actuator, is used as the triggering element.

The position of the magnet is determined by the sensor element and transmitted as analogue or digital signal output.

As there is no mechanical coupling between the sensor and control element, the devices are completely free of wear, require virtually no maintenance and provide a long service life even under extreme conditions.
