Amiteq Co., Ltd.

Amiteq Co., Ltd. (株式会社アミテック) is a Japanese sensor manufacturer based in Beppu, Oita Prefecture, according to its Wikidata entry. The company designs and supplies inductive position sensors for industrial equipment and automotive systems, positioning itself as a specialist engineering partner that tailors sensor performance and dimensions to each customer application rather than selling only catalogue-standard parts. Amiteq's product families cover several measurement domains. Its angular sensor line is built around the INDUCTCODER® inductive encoder, offered in high-precision formats, segment-type designs for large-diameter shafts, and multi-turn absolute versions that operate without a battery. Its linear sensor line, marketed under the INDUCTSCALE® and INDUCTGAGE® names, spans high-temperature long-stroke absolute types, ultra-compact high-resolution units, high-noise-immunity semi-absolute models, and thin, small-diameter ultra-high-precision variants. Applications cited by the company include engine valve-lift control, spot-welding electrode gap control, milling-machine table positioning, and lathe tool positioning. Beyond linear and angular sensing, Amiteq offers 2-D planar position sensors that output at least two axes of displacement data simultaneously, with optional tilt and rotation-angle measurement, aimed at X-Y positioning and centering on machine tools. It also produces pressure and force sensors using a proprietary detection principle that avoids strain gauges and tolerates spike pressures and impact loads, as well as special-application sensors such as steering-angle sensors for automotive use, including a PCB-type multi-turn absolute design that is magnet-free and unaffected by gear backlash. The company's public messaging emphasizes application-specific engineering: sensor performance, dimensions and packaging can be adapted to each use case. Its website lists sensor examples with specifications such as resolutions down to 0.0001 mm, operating temperatures from -40 to 155 °C, and compact packages as small as φ3 x 15 mm. Amiteq serves both industrial machinery and automotive customers, and its trademarks include INDUCTCODER®, INDUCTSCALE®, INDUCTGAGE® and CYLSCALE®. The company remains privately held and active.

Amiteq Co., Ltd. is a Japanese sensor manufacturer headquartered in Beppu, Oita Prefecture, as recorded in its Wikidata entry. The company operates in the industrial and automotive sensor field, developing inductive position-sensing technology marketed under its own registered trademarks. Amiteq's public product documentation describes a portfolio built around inductive sensing principles. Its angular sensor family is led by the INDUCTCODER® inductive encoder, which the company presents as combining high precision with high tolerance to sensor mounting and mechanical errors. Variants include a segment (divided) type suited to large-diameter shaft applications, and a multi-turn absolute type that detects multi-turn absolute angle without a battery, with an example specification of 256 turns (92,160°) in a compact φ45 mm package with a built-in signal converter. The linear sensor line, sold under the INDUCTSCALE® and INDUCTGAGE® names, includes a high-temperature, long-stroke absolute type with an operating temperature range of -40 to 155 °C, an absolute stroke of 20 mm, impact resistance of 25G/6 ms and oil resistance at 100 °C, cited for engine valve-lift control. An ultra-compact type measuring φ3 x 15 mm offers an 8 mm absolute stroke and 0.0006 mm resolution, cited for spot-welding electrode gap control. A high-resolution, high-noise-immunity semi-absolute type offers 0.0005 mm resolution and ±0.004%/m accuracy in a φ10 x 14 mm package, cited for milling-machine table positioning. A thin, small-diameter ultra-high-precision type achieves ±0.0002%/m accuracy and 0.0001 mm resolution in a φ36 x 13 mm package, cited for lathe tool positioning. The INDUCTGAGE® variant is designed for integration with shaft motors, eliminating the need for an external linear scale. The company also produces 2-D planar position sensors that simultaneously measure and output at least two axes of displacement with high resolution (example 0.001 mm) in a φ20 x 14 mm package, with optional tilt and rotation-angle measurement, aimed at X-Y positioning and centering for machine tools. Its pressure and force sensors use a proprietary detection principle that does not rely on strain gauges, allowing them to withstand spike pressures and impact loads. Special-application sensors include steering-angle sensors for automotive use, including a PCB-type multi-turn absolute design (±900°) that is magnet-free and unaffected by gear backlash. Amiteq's website, copyrighted 2012, presents these products as examples, emphasizing that sensor performance and dimensions can be designed to match each application. The company serves both industrial machinery and automotive customers. Its registered trademarks include INDUCTCODER®, INDUCTSCALE®, INDUCTGAGE® and CYLSCALE®. The company is privately held and remains active.
