PlungerProx

Robust Mechanical-Inductive Detection

Balluff's PlungerProx is a high-durability inductive proximity sensor actuation system for applications where loose tolerances make direct contact unavoidable. The heavy-duty spring-loaded probe makes direct contact with the machine or part to verify presence or position, making it ideal for welding fixtures, stamping dies, and part ejection verification. PlungerProx is supplied with a specifically-selected Balluff M08 PNP or NPN inductive sensor that is protected inside the mechanical housing, where it never makes mechanical contact with any moving parts. Various plunger tip profiles are available to meet application requirements, including one type with a threaded hole in the end for installation of custom tips. The PlungerProx is built with serviceability in mind, and can be quickly disassembled for cleaning and worn or damaged part replacement.
