2. Product Summary MONOSASHI-KUN is a cylinder that has a built-in linear encoder. The scale of the magnetic rod and magnetic sensor detects change in piston position, and pulse signal is outputted with A/B quadrature pulse (90 ゚ nominal phase relationship). Position detection in 0.1 mm resolution is possible by inputting this signal to CEU5.
2-3 Precautions on Selection ● Use MONOSASHI-KUN CE1 with Multi-Counter CEU5. ● For SMC CE1 series and SMC CEU5 series, operation check was performed with SMC extension cable CE1-R※※ for the maximum wire length of 23m. Since operation check was not performed with other counters and cables, a system designer who selects equipment should check the operation.

The connector pin layout shows the layout of CE1 with connector. 4-2 Wiring for Counter CEU5 sensor input part The wiring for CEU5 and MONOSASHI-KUN Monosashi-kun series uses three twisted-pair cables.
5. Structure and Measuring Principle 5-1 Structure Cylinder body Sensor head Piston rod ・A part of the piston rod has scale (magnetic scale). In order to maintain the relative position of the scale and the sensor head, piston rod is used to have a structure of non-rotating cylinder. !...
5-2 Measuring Principle MONOSASHI-KUN is an air cylinder that has a function to output piston stroke movement as pulse signal in 0.1 mm resolution. Measuring Principle is as follows. ① Amplification ② Counter & Interpolation Circuit Movement Magnetic resistive element Magnet A-phase Piston rod...
