Incremental encoder features:
Incremental encoders are characterized by: non-contact, no friction and wear, small size, light weight, compact, easy to install, easy maintenance, drive torque is small, its high precision, large measuring, fast response, The digitized output characteristics;
Incremental encoder is ideal for measuring speed, unlimited accumulation measure. But there is zero cumulative error, poor immunity, the receiving device downtime required power and memory, power should give change or reference position and other issues, such as the selection of these problems can be solved absolute encoder.
Built-in battery technology:
Some encoder built-in battery power to avoid signal loss, there are some single-turn encoder is an absolute signal, and the signal is more than circle the number of built-in battery and the circuit incremental counting method to obtain, this is a pseudo-absolute encoders, by its battery life, battery failure low by bad vibration and other factors affect the battery contacts, and greatly reduce reliability.
4, incremental encoders General Application:
Speed, measuring the rotational direction, the mobile measuring angle, distance (relative).
