Guide to Linear Encoders Due to the discontinuation of the Keyence "VP-90," Makome Laboratory is proposing replacement products. As a replacement for the Keyence "VP-90," Makome Laboratory recommends the magnetic linear encoder "SI-140" system. The "SI-140" system utilizes magnetism to measure a scale that is magnetized alternately and evenly with N and S poles, in a non-contact manner. Because it uses magnetism, it can measure lengths without being affected by non-magnetic materials. The head has a protection structure rated IP67 (compliant with IEC standards). The output is in A and B phase with a resolution of 0.1mm. When using an incremental measurement device with a 4x multiplier, it can be used at 0.025mm. The detection distance between the head and the scale is 4±3mm (1 to 7mm), allowing for some variation in distance. The output circuit is a MOS FET open-drain output, which can be extended up to 5m. Additionally, there is a separate line driver output type that can be extended up to 100m. *The MOS FET open-drain is almost equivalent to an NPN transistor output.
