Position Sensor Selection Guide

A hybrid stepping motor position sensor provides critical insight into your stepper motor’s position, rotation distance, and speed. We offer a range of encoders, each designed with distinct features and advantages. In this guide, our expert engineers at NMBTC will help you choose the right hybrid motor position sensor tailored to your specific application.

Application Examples

hybrid motor pump application

Pump

Position sensor type: Hall IC “S” Series

Step-out detection is possible for pumps that rotate in a single direction. This is well-suited for applications where rotation needs to be monitored, but precise position or direction of rotation is not necessary.

  • Dishwasher pumps
  • Medical pumps
  • Dispenser pumps
hybrid motor belt conveyor

Belt Conveyor

Position sensor type: Optical Encoder “IG” Series

Supports bidirectional rotation making it ideal for infinite feed applications that require angle detection without the need for high precision, origin signal, or speed data.

  • Medical specimen transport conveyor
  • Food transport conveyor
  • Product sorting conveyor
hybrid motor electric slider

Electric Slider

Position sensor type: Magnetic Encoder “N, K” Series

Recommended for finite-length feed applications with bidirectional rotation. Ideal for high-precision angle detection, origin signals, and rotation speed monitoring.

  • XYZ robot
  • Electric actuator
  • Precision positioning device

 

hybrid motor flow regulating valve

Flow Regulating Valve

Position sensor type: Magnetic Absolute Encoder “M” Series

Recommended for limited-range applications where position data must be retained during power loss. Ideal when resuming operation without returning to the origin.

  • Semiconductor gas valve
  • Water flow control valve
  • Chemical liquid control valve
