Novotechnik, U.S. introduces the LWX-003/004 Series of position sensors designed for extremely harsh environments. The all metal sensor shaft features a pressure equalisation valve and the LWX-004 version also provides rod protection over its range of motion with an SS304 alloy, 0.9 mm thick stainless steel shield.
The LWX Series’ differential pressure compensation system compensates for the pump effect – pressure that can build up due to push rod movement. This feature, together with a hydraulic shaft seal, provides protection against ingress of liquids and dust. Seal rating is IP67. Backlash-free pivot heads are designed for easy mounting and permit ±12.5% free movement.
Other key specifications for the LWX Series include operation with shock to 50 g and vibration to 20 g, stroke lengths from 50 to 750 mm, linearity to 0.04%, life of more than 50 million movements and repeatability of 0.01 mm.
