Optical Rotary Encoder

RE25 Series
OutlineRE25 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 equipments, industrial machineries, telecommunication devices andmachine tools.

Features● Eco friendly:

1) Power-saving
2) Low cost and lesser parts by VA design
3) RoHS compliant● Thin-line (18.8x25.5x8.9mm) and lightweight (18g)● Various types of models with options: lead wire with or without connector, clamp forhorizontal/vertical mounting● Long-lasting without “contact chatter” due to its optical switching function● Waterproofed model availableSpecifications
