RP SCALE, RPB series.

Linear Detector with LBJ Model Encode

  • The rack and pinion mechanism eliminates complex installation. A joint fitted to the linearity operating section allows adjustments to within 1 mm.
  • Resolution is 0.1 mm, and accuracy is  0.2 mm for 1000 mm of a stroke.
  • Most suitable for injection molding machines, various types of cutting mechanisms and other automated machines.

High Frequency Pulse Generator, SHE series.

Features

  • No contact point-therefore no torque.
  • High-frequency operation enables long life service.
  • Even when speed is varied from 0-5 kHz, the peak valuable of the signal is constant.
  • Long distance of transmission can be provided, because there is little interference from electromagnetic inductions.
  • Operates at low temperature down to -20oC
  • Compact and light, yet resistant to vibration, oil and dust.
Application
  • Revolution speed detector for tachometers, proportional meters and various converters
  • Detector for counters for automatic cutting in lengths and length adjustment
  • Digital processing as a pulse generator
  • Detector for speed control (F/V converter
  • For applications that require no torque, no contact point or long life service

Gear Sensor, MSE series.

Features

  • Highly reliable. Used to detect the speed of railway trains.
  • Detects speeds by sensing iron gear. This sensor outputs dual square signals in quadrature, which agree with gear revolution.
  • Resistant to mechanical shocks, such as vibration, as well as immersion (equivalent to IPX7)
