• ABSOLUTE electromagnetic induction linear encoder system is introduced.
  • Snap mechanism allows continuous and easy measurement without moving the slider by using the lever.
  • The ABSOLUTE Digimatic snap caliper features a spring-loaded mechanism to allow quick and efficient GO/NO-GO inspection for mass production parts.
  • Allows step measurement
  • Displacement of snap part is 2 mm.
  • Measuring force: 7N to 14N
  • Absolute type. (Refer to page D-8 for a description of Absolute measurement.)
  • Allows integration into statistical process control and measurement systems for models with measurement data output connector. Refer to page A-3.
