Transmission applications

Gear sensors increase performance efficiency and reduce emissions. The function and flexibility of modern gearboxes require sensors which, by short response times and high accuracies, contribute to optimising driving comfort while at the same time reducing fuel consumption. Besides a wide range of robust sensors with a multitude of applications in gearboxes, we offer position sensors with multi-functional design as well as innovative sensor clusters for gathering pressure and temperature.

Speed sensors for transmission applications

Our engineers understand optimal control means: higher efficiency, lower emissions and an increase in driving pleasure
In order to handle resources in a responsible way and to protect the environment, it is necessary to measure precisely, even at a low rotational speed, immediately when the engine of a vehicle has been started.
Detecting rotational speeds without loss enables optimal engine control resulting in improved driving characteristics and low emissions.

Special features

  • Working range up to 3 mm
  • Temperature range -40 °C to +160 °C
  • Protection rating up to IP 69
  • Detection of direction

Special application: gear detection sensor

Gear sensor for detection of all gear positions replace traditional
systems and offers additional comfort feature

In the “start / stop automatic / hill-start assist application” the gear detection sensor detects all gear positions in the vehicle gearbox system independent of rpm and vehicle speed.
A sensor (redundant, if necessary) moving over a mechanic specialdesign template inside the gearbox enables non-contact, threedimensional measurement and recognition of all gear positions.
Additional benefits are achieved through weight and cost reduction compared to conventional systems. Installation with only one bolt, whose size and torque are matched to the existing series process, is also advantageous. Thus the position of the gear-change shaft can be measured directly without any mechanic contact and with only a single sensor, which enables the problem-free detection and output of up to eight gears, the neutral position and of course the transitional state. The latter in particular enables the control device to prepare to implement the intention to change.
Fast, accurate, and having a high cost-benefit ratio, the sensor featuring a special-design template replaces conventional switching systems.
