4T755 – 125Khz Electronic Encoder

4T755 - 125Khz Electronic Encoder

Miniature Electronic Incremental Encoder

A small, high precision encoder with a 10mm blind hollow shaft the 4T755 has a 125Khz frequency response and can mount directly onto motor shafts. Quadrature output and Flexible mounting bracket.

Series 4T755 encoders are ideal for applications requiring a miniature, high precision low cost encoder. The encoder has a flexible mounting and a blind hollow shaft (10mm diameter) for mounting directly onto motor shafts etc. the Output circuit has a push/pull output as standard, signals A, B, output.


  • Quadrature output
  • Fixable by flexible mountings
  • 10 mm blind hollow shaft
  • Ideal replacement for mechanical counters when used in conjunction with a suitable electronic counter
  • Operates at output frequency of up to 300 KHz
