YeuLian MPG series design to enhance the applicability of the product by using metalworking material. It can protect the handwheel from dust, water and oil. The encoder adopts optical rotation and non-contact detection structure. Thus, it will not cause vibration and affect the signal output. The rotary encoder can withstand 3 million circles of wear and tear. The accuracy remains the same, high precision performance. It designs anti-static, wide supply voltage DC5V to 24V, makes the high reliability and strong consistency. Faulty wiring will not damage, because of the voltage protection circuit design, just re-wiring and the functions are normal. It is easy to install and replace, and it is suitable for all kinds of automation equipment and CNC numerical control system machine tools. Apply for the external handheld box unit and the CNC operation panel.
