Tosoku RE25 Series Optical Rotary Encoder

Product Made in Japan
Manufacturer: Tosoku
Model: RE25 Series

RE25 is a VA designed eco-friendly – power-saving and low-cost with lesser parts – rotary encoder. Its size, mounting procedures, and inner structures have been designed for a wide array of uses; measurement devices, medical equipment, industrial machinery, telecommunication devices, and machine tools.

Features

● Eco-friendly:
1) Power-saving
2) Low cost and lesser parts by VA design
3) RoHS compliant
● Thin-line (18.8×25.5×8.9mm) and lightweight (18g)
● Various types of models with options: lead wire with or without connector, clamp for horizontal/vertical mounting
● Long-lasting without “contact chatter” due to its optical switching function
● Waterproofed model available

Output Waveform

1) Turning the shaft clockwise will generate the signal A when the signal B outputs a low voltage (0);
2) Rotating the shaft counter-clockwise will generate the signal A when the signal B outputs a high voltage(1);
3) Detent positions are where both signals A and B are low (0).
