Considerations for selecting incremental linear encoders
When selecting incremental linear encoders for your application, several important factors should be considered to ensure optimal performance and compatibility:
- Measurement range: Determine the required sensing range for your specific application. The encoder should be able to accommodate the full extent of linear movement you need to measure, as this will directly impact the accuracy of your measurements.
- Resolution: Evaluate the encoder's resolution, which indicates how finely it can measure distance. Higher resolution encoders provide more precise position feedback, making them ideal for applications where small movements are critical.
- Output type: Incremental linear encoders can offer various output types, including quadrature, analog, or digital signals. Ensure that the output type is compatible with your control systems for seamless integration and effective data acquisition.
- Environmental conditions: Consider the operational environment where the encoder will be used. Factors such as temperature extremes, humidity, dust, and exposure to chemicals can affect performance. Choose an encoder designed to withstand these specific conditions.
- Mounting and size: Assess the available space for installation and the mounting requirements of the encoder. Make sure the physical dimensions and mounting options of the selected encoder fit within your system's design constraints.
- Speed and response time: Depending on your application, the speed of operation and the encoder's response time may be crucial. Select encoders that can handle the required speed and provide timely data updates for dynamic applications.

Frequently asked questions about Incremental linear encoders
Answers to the most important technical Questions
How can a linear displacement be measured using an incremental encoder?
Linear movement can be converted into incremental signals using a measuring wheel, rack, magnetic tape or a similar mechanical coupling. The encoder generates pulses that are counted by the control system. The distance travelled is then calculated based on the number of pulses and the known resolution.
Since an incremental encoder only detects changes in position, the system generally requires a reference point or homing procedure after power-up. Once this has been completed, the control system can accurately determine the direction of movement, speed and relative position.
For reliable linear displacement measurement, important factors include the appropriate resolution, backlash-free mechanical coupling, reliable signal transmission and stable mounting.
We will be happy to help you select the right linear incremental encoder for your application.
When is an incremental encoder sufficient, and when is an absolute sensor required?
An incremental encoder is sufficient when only relative movement or changes in position need to be measured and the system can perform a homing procedure after power-up.
It is well suited to applications with a defined starting point, short periods of downtime and control systems that can reliably process encoder pulses. Important selection criteria include measuring range, resolution, output signal, speed, response time and environmental conditions.
An absolute sensor is required when the exact position must be known immediately after power-up or following a power failure. This is particularly important in safety-related applications, hard-to-access axes, hydraulic cylinders, mobile machinery or processes where homing is not possible or would take too much time.
Magnetostrictive position sensors, for example, are absolute measuring systems that offer high reading accuracy and strong resistance to shock, vibration and contamination.
What resolution can be achieved with linear incremental encoders?
Linear incremental encoders can achieve very high resolutions, depending on their design. For magnetic linear incremental encoders such as the MPS model, the standard resolution is 5 µm in 4x evaluation mode. Optional resolutions of 2.5 µm, 5 µm, 10 µm, 12.5 µm, 20 µm and 25 µm are also available.
The appropriate resolution depends on the application, measuring range, required positioning accuracy, movement speed and signal processing.
Higher resolution provides more precise position feedback and is particularly useful for accurately detecting very small linear movements.
