Bircher Reglomat AG DWJK170 Air-Wave Switch

The Bircher Reglomat AG DWJK170 Air-Wave Switch is a sealed pneumatic pressure-wave switch used as the sensing element in automatic doors, gates, and safety barriers. It operates by responding to pressure changes transmitted through an air line rather than by physical contact, delivering fast, contactless actuation of the safety output. As part of the Bircher Air-Wave family, the DWJK170 follows a proven design that supports rugged reliability in industrial environments and is typically mounted within a protective housing that includes an air connection interface. Bircher notes that pressure-wave switches have a long field history and have been deployed in millions of units in service, reflecting their robustness and low maintenance profile. Typical applications include safety edges on industrial doors, along with automatic door and barrier systems in mass transit, warehouses, and manufacturing facilities where rapid closure and dependable sensing are required. The DWJK170 shares the DW-series emphasis on straightforward installation, compatibility with Bircher housings, and durable construction designed to withstand common environmental influences.
