Detection scale

30 m x 0.3 mm x 280/475 mm
(H x W x D)

75 x 22.5 x 80 mm (H x W x D)

Features

• Unique optical system design ensures resistance to scale rattling. (Detection is possible if the detection scale is within a range of 6 mm (±3 mm).
• Unique optical, circuit, and structural design ensures low costs.
• Resolution of 1 mm is ideal for positioning in conveyor applications.

• Provides discrimination output for rotation direction in response to phase-difference signals from Rotary Encoder.
• Response frequency of 120 kHz ensures high-speed responses.
• DIN track mounting is possible, and thin body ensures efficient mounting.
