New Shaft Protected Position Sensors
Southborough, MA… 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 equalization 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.

T.J. Davies' Retention Knobs
Our retention knobs are manufactured above international standards or to machine builder specifications. Retention knobs are manufactured utilizing AMS-6274/AISI-8620 alloy steel drawn in the United States. Threads are single-pointed on our lathes while manufacturing all other retention knob features to ensure high concentricity. Our process ensures that our threads are balanced (lead in/lead out at 180 degrees.) Each retention knob is carburized (hardened) to 58-62HRC, and case depth is .020-.030. Core hardness 40HRC. Each retention knob is coated utilizing a hot black oxide coating to military specifications. Our retention knobs are 100% covered in black oxide to prevent rust. All retention knob surfaces (not just mating surfaces) have a precision finish of 32 RMA micro or better: ISO grade 6N. Each retention knob is magnetic particle tested and tested at 2.5 times the pulling force of the drawbar. Certifications are maintained for each step in the manufacturing process for traceability.
