PLCD Position Sensors for Exhaust Gas Recirculation of Truck Engines

Tyco Electronics: New emission laws demand new technologies for optimization of the combustion process. Along with the addition of chemical substances (SCR) there is also the significant technology of exhaust gas recirculation.

A pneumatic cylinder, controlling a flap, regulates the volume of exhaust gas which is recirculated. For precise control in this application, a displacement sensor has to fulfil these requirements

• Safe fixture on the cylinder
• Wear free measurement with millions of cycles of the actuator
• Very precise measurement
• Suitable for temperatures up to 150°C
• High resistance against vibration

For precise measurements of displacement and positions, Tyco Electronics employs the PLCD sensor (Permanentmagnetic Linear Contactless Displacement). As a sensor manufacturer and development partner in the automotive industry, Tyco Electronics offers their long experience of development and project engineering for new sensor application systems.

Diverse portfolios of electromagnetic components and sensors are available, with modern process technologies, and are the basis of successful products within the automotive industry.
