Novotechnik LWX-003/004 position sensors
The LWX-003/004 series of position sensors is designed for harsh environments. The all-metal sensor shaft features a pressure equalization valve. The LWX-004 version also provides rod protection over its range of motion with an SS304 alloy 0.9-mm-thick stainless steel shield. A differential pressure compensation system compensates for the pump effect, or pressure that can build up because of push rod movement. This feature, together with a hydraulic shaft seal, provides protection against ingress of liquids and dust. The seal rating is IP67. Backlash-free pivot heads are designed for easy mounting and permit ±12.5% free movement.
