Ready to use right after purchase! Comes with a display, magnetic encoder "SI-140 Package" length measurement system, also for Kaizen proposals.

The SI-140PAC is a packaged linear encoder that comes with a display unit and can be used immediately with a power supply of AC100V. It is equipped with a standard 2-meter magnetic scale, which can be extended later (maximum length ∞). The counter display has a minimum display value of 0.1mm. You can easily measure with digital display where you previously used tape measures or gauges. Suitable for cutting aluminum and woodworking materials. Detection is non-contact. It has been widely adopted in in-house jigs (contributing to improvement proposals). Please also use it for DIY projects. Since it is magnetic, there are no miscounts due to dirt. Available on YouTube. *Sample lending is possible. *For more details, please contact us or download the PDF materials.

Linear Encoder "SI-140" System

Proposal for replacement of Keyence Corporation's "VP-90".

  • Product news

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. Please contact us for evaluation samples.

Delivery Exhibition (Traveling Exhibition) We will hold a "delivery exhibition" at your company's space! Magnetic sensor manufacturer, Makome Laboratory.

  • Seminar・Event

Our company is a sensor manufacturer specializing in magnetic applications. 【Do you have any of these thoughts?】 - We can't send all employees to the exhibition. - We went to the exhibition, but couldn't take our time to look around. - We want to share products with all employees because they seem useful! To respond to such voices, we will hold a "Mobile Exhibition." 【Could unexpected suggestions for improvement come from other departments?】 【What is a Mobile Exhibition?】 We will hold a mini-exhibition in your company's meeting rooms, cafeterias, hallways, or other spaces. A space with one or two long tables is sufficient. The duration can be discussed, ranging from half a day to several days. It can be held during lunch breaks or after working hours (please also inquire about weekend events). If you specify the products you wish to see in advance, we will definitely display them. As a company that values sincere engagement with our customers, we have created an opportunity for you to have a relaxed conversation with us. If you have any concerns regarding sensing, please feel free to consult us. ● Please also feel free to reach out for private exhibitions hosted by trading companies. *There are no costs involved, but we ask that you provide the space and an AC 100V power supply.
