Self-contained position detection apparatus

摘要

A position detector includes an outer tube of having a magnetostrictive wire disposed therein. An electric circuit is mounted completely within the outer tube and is electrically connected to a pickup coupled to the magnetostrictive wire. A multi-pin connector is mounted at one end of the outer tube for coupling conductors extending from the circuit in the outer tube to external conductors. In an alternative embodiment, the position detector includes a threaded adapter threadingly mountable within an end wall of a pressurized fluid operated cylinder. Conductors extend from the circuit in the outer tube through the adapter to an external connector.
