Structure for mounting actuating rod stroke sensor to hydraulic cylinder

摘要

A structure for mounting an actuating rod stroke sensor to a hydraulic cylinder is disclosed. The sensor mounting structure has a sensor holder which is mounted to a predetermined portion of a cylinder head. A circuit board is tightly set in the sensor holder and holds the stroke sensor in the sensor holder. The above structure improves the operational precision of the stroke sensing operation and effectively fixes the sensor to the cylinder. The structure also protects the stroke sensor from the frictional heat generated during the reciprocating motions of the actuating rod, thereby lengthening the expected life span of the stroke sensor.
