Electronic Incremental Encoder


Compact 30mm encoder with Quadrature output, 10mm hollow shaft and a 100°C operating temperature. This encoder is ideal when space is limited.

The series 4T260 low profile 30 mm package design makes it a perfect solution for many machine and motor applications. the unit has a complete 10mm through-shaft design. The series 260 and its integral bearing set provide for stable and consistent operation, without concerns for axial or radial shaft runout. The standard 100° temperature capability allows servo motors to operate at higher power outputs and duty cycles. The output has a push/pull output as standard, signals A, B output.


  • Quadrature output.
  • Anti-rotation flex mount arm.
  • 10 mm hollow through shaft.
  • Ideal replacement for mechanical counters when used in conjunction with a suitable electronic counter.
  • Operates in temperatures up to 100°C.
  • Operates at output frequency of up to 300 KHz.
