CERP-7400 Roller encoder

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.
Anti-slip roller which is made of urethane-coating hard rubber

Using with the TM-4100 series enable direct reading of speed measurement without complicated calculation.
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) in combination of TM-4300 series.
