Using Industrial Cylinders for High Shock, Vibration and Pressure

Hydraulic cylinders need feedback devices to resist high pressure, shock, and vibration as well as withstand temperature fluctuations while providing very high repeatability over a long duration. In general, a resolution of ±0.001″ is needed to offer the required feedback. For appropriate installation and maintenance, it is necessary for mounting to be simple and direct. A precise output type is needed for every application.

Industrial Cylinders


The 953 VMax LDT is a perfect solution for application in hydraulic cylinders. It offers absolute feedback and has been designed to resist severe environments with a static pressure of 5000 psi, random vibration of up to 30 Gs, and shocks of 1000 Gs. Digital and analog outputs can be wired back to the host PLC to provide exact position feedback. A 3/4-16 mounting thread (or optional metric M18x1.5) enables simple and rapid installation. The 953 VMax withstands temperatures of −40°C to 85 °C and provides several outputs including analog, digital start/stop, and variable pulse (PWM).


  • The 953 VMax’s strong construction avoids downtime
  • Diagnostic LED
  • Ability to use competitive magnets
  • Removable cartridge
  • Output options enable cost-effective and simple interface to equipment
  • IP68
  • Broad input power range of 7–30 VDC
  • Prevents drift and avoids the need to calibrate, thereby reducing scrap and labor costs
  • Field programmable field and span


The 953 VMax LDT is right at home even in hostile applications.
