Environmentally Sealed Switch Rated For One Million Cycles

HSI's 6700 Series environmentally sealed switch is rated for one million cycles. The 6700 was developed for high cycle harsh environment applications. The need for high cycle limit switches has developed as aerospace and industrial systems have evolved from manual control and feed-back to computer controlled mechanisms. The 6700 meets the high life cycle requirements of modern computer controlled systems. Based on the proven design of HSIs 6100 Series switch, the 6700 incorporates material and process changes to achieve reliable 1 million cycle life. Internal blade material thickness, temper and surface treatment have been optimized in the new design. The metal housing and operating pin are permanently bonded to a resilient elastomor seal. This ensures environmental seal integrity of 1 x 10 rays to -6 Atm cc/sec. The switch is configured for operation in the milliamp range. Operating temperature is -85degreeF to +300degreeF. The 6700 Series switches are available in a wide variety of actuator assemblies. Typical assemblies include leaf actuators, coller leaf assemblies and plunger actuators. HSI can also provide customization assemblies to meet specific operational requirements.
