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

マコメ研究所   (MACOME) マコメ研究所 (MACOME) 本社
Guide to Linear Encoders Due to the discontinuation of the Keyence model "VP-90," Makome Laboratory is proposing replacement products. As a replacement for the Keyence "VP-90," Makome Laboratory recommends the magnetic linear encoder system "SI-140." The "SI-140" system utilizes magnetism to measure a scale that is evenly magnetized with alternating 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 protective structure rated IP67 (compliant with IEC standards). The output is provided as A and B phase outputs with a resolution of 0.1 mm. By using an incremental measurement device to quadruple the measurement, it can be used at 0.025 mm. The detection distance between the head and the scale is 4±3 mm (1 to 7 mm), allowing for some variation in distance. The output circuit is a MOS FET open-drain output, which can be extended up to 5 meters. Additionally, there is a separate line driver output type that can be extended up to 100 meters. *The MOS FET open-drain is almost equivalent to an NPN transistor output. Please contact us for evaluation samples.

Linear encoder (linear scale) SI-140 magnetic scale

Linear encoder, compact and lightweight magnetic incremental scale system, waterproof specification (IP-67), suitable for replacement of optical systems.

This is a non-contact incremental magnetic scale system that allows for a large distance between the head and the scale. It can measure length without being affected by dust, dirt, etc., due to magnetic detection. It features the smallest head among our magnetic detection scales. The detection head is compact, measuring 30mm in width and 32mm in height. When combined with a dedicated scale, it can create a compact length measurement system. The large detection distance between the head and the scale, along with the tolerance for variations in detection distance, increases design flexibility. 【Features】 - Non-contact incremental scale system that allows for a large distance between the head and the scale. - Length measurement is possible without being affected by dust, dirt, etc., due to magnetic detection. It can detect through non-magnetic materials such as brass, aluminum, plastic, and stainless steel (e.g., SUS303). It has a waterproof structure (IP-67) and has been successfully adopted in food processing machines. *Sample lending is available. *For more details, please contact us or download the catalog. CAD data is available. There are many successful replacements from discontinued optical encoders! *VP-90 Easy Scale.

SI-140PAC.jpg

Linear encoder package with 0.1mm display - video available

Ready to use right after purchase! Includes display unit. Magnetic encoder "SI-140 Package" length measurement system. Also suitable for Kaizen proposals.

The SI-140PAC is a packaged linear encoder that comes with a display and can be used immediately with an AC100V power supply. It is equipped with a standard 2m 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 used to measure with tape measures or gauges. It is suitable for cutting aluminum materials and woodworking. 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. There is a YouTube channel available. *Sample lending is possible. *For more details, please contact us or download the PDF materials.

On February 26, 2026, an advertisement for the bridge expansion device "Hybrid Joint" was published in the Tohoku 6 Prefectures edition of the Sankei Shimbun, demonstrating a durability of 100 years (3LII type) verified by a third-party organization.

  • NEW
  • COMPANY

Crittec Industries Co., Ltd. published a newspaper advertisement (black and white, full-page 15 columns) for the bridge expansion device "Hybrid Joint" in the February 26, 2026 issue of the Sankei Shimbun Tohoku 6 Prefectures edition. In Japan, the number of bridges over 50 years old is rapidly increasing, making the longevity of bridges a critical issue. The expansion devices, which are considered a cause of bridge damage, require high water-tightness and long-term durability. Our expansion device "Hybrid Joint" offers multiple types tailored to different bridge types and conditions. Among them, the "Hybrid Joint 3LII type" has demonstrated a durability of 100 years in fatigue loading tests conducted by a third-party organization. It has successfully passed 12 million cycles of repeated loading at a maximum load of 260 kN, confirming performance equivalent to a 100-year design service life for bridges. We have numerous delivery records in the six Tohoku prefectures and can accommodate a wide range of bridge types, including steel and PC bridges. The special website linked to the advertisement allows for the review of detailed materials and inquiries or requests for documents. Please make use of it for comparing and considering bridge renewal and repair plans. Crittec Industries will continue to contribute to the longevity of bridges nationwide, starting with the Tohoku region.

[New Product] High brightness × wide × high cost performance. Announcement of the linear lighting LLWK-N series born from a field perspective.

  • NEW
  • PRODUCT

Born from the voices on the ground, high brightness × wide coverage × high cost performance linear lighting. To respond to the production site’s demands for "brighter," "wider," and "easier to use," we have launched the new high brightness linear lighting LLWK-N series, which balances high brightness and high cost performance. While achieving approximately three times the illuminance compared to the conventional LLWG series, we maintain an easy-to-implement price range. With a natural heat dissipation structure suitable for clean rooms and a compatible design that makes it easy to replace existing lines, we are thoroughly pursuing the "ease of use" required on-site. For detailed product specifications and inquiries about implementation, please feel free to contact us.
