Tosoku RE23 Series Optical Rotary Encoder with Push Switch

Product Made in Japan
Manufacturer: Tosoku
Model: RE23 Series

RE23 series are optical rotary encoders with dual functions of pushing and rotating on its shaft. Its size, mounting procedures and inner-structures have been designed for a wide-array of uses; measurement devices, medical equipments, industrial machineries, telecommunication devices and machine tools.

Features

● Multi-functional with 2 way acting – pushing and rotating – shaft
● Eco-friendly:
1) Low cost and lesser parts by VA design
2) 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

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).

Precautions

Wiring	Use buffering amplifier when extending lead wire over 30cm.
Soldering	Do not put a load on the terminal area during and immediately after soldering.
Operation	Do not use flow/reflow soldering machines.
Power	Use under specified power voltage and connect properly.
Waterproofing	Do not fasten tighter with the torque of more than 1.5N･m.
