Roller encoders enable line speed and distance measurements

ce

RP-7400

Ideal for linear measurement of moving objects

  • Conforms to RoHS, CE marking
  • Speed measurement:120 P/R, 1200 P/R, Length measurement:200 P/R
  • Easy measurement by only pressing the roller against moving object.
  • Grippy roller which is made of urethane-coating rubber
  • Using with the TM-3100 series enable direct reading of speed measurement.
  • Speed measurement can be performed with 0.01 m/min (1200 P/R).
  • Length measurement can be performed with 1 mm/pulse (200 P/R).
