NSD

What NSD does

NSD Corporation (エヌエスディ) is a privately held Japanese mechatronics manufacturer headquartered in Nagoya, founded around 1955-1958 and operating within the NSD Group alongside its wholly-owned sales subsidiary NSD Sales Corporation (NSD販売株式会社). The company designs and manufactures industrial position detection sensors, converters, and controllers built around its proprietary ABSOCODER electromagnetic induction technology, which provides absolute rotary and linear position feedback without optical encoding or battery backup and is engineered for harsh industrial environments such as steel mills, chemical plants, and explosion-hazard areas. Its product portfolio spans single-turn and multi-turn rotary detectors (VRE, MRE), linear detectors (VLS), cylinder-integrated sensors (CYLNUC, Inrodsensor), and a broad converter family supporting binary/Gray code, pulse output, and major industrial network protocols (EtherNet/IP, EtherCAT, PROFINET, PROFIBUS-DP, CC-Link, CC-Link IE TSN, DeviceNet, SSI), together with controller products such as VARICAM electronic cam switches, VARILIMIT limit switch controllers, and the ezABSO electromagnetic induction rotary encoder line.

NSD operates a three-pillar business model combining in-house manufacturing (maker), ODM design and production under customer brands, and trading/sourcing services. Revenue is generated through direct enterprise sales via sales offices across Japan (Tokyo, Nagoya, Toyota, Osaka, Hamamatsu, Hiroshima, Fukuoka) plus authorized distributors in Korea, Southeast Asia, the USA, Germany, and China, with products configured to customer specifications and priced by quotation rather than through mass-market channels. The company maintains deep integration partnerships with all major Japanese industrial control vendors, including Mitsubishi Electric MELSEC, Omron, Yaskawa Electric, Hitachi Industrial Solutions, Toshiba, and Fuji Electric, as well as dedicated PLC unit-mounted converters for each platform. Recent product launches (NCX Series 2026, ezABSO Network Series CC-Link IE TSN 2025) and continued facility expansion (Shinohara Third Factory 2020) demonstrate ongoing investment in next-generation products and manufacturing capacity to serve existing steel, tire, converting, water, and chemical industry customers.

Revenue model

1. Position Detection Sensors (Hardware Sales): NSD manufactures and sells position detection sensors including absocoders (rotary and linear encoders), magnet switches, eddy current displacement sensors, tension meters, and non-contact transmission devices. Products are sold directly to industrial customers in steel, tire, converting, and water management sectors. The company also provides ODM services building products under customer brands, and trading services sourcing products aligned with customer needs.
2. ODM / Custom Product Development: NSD designs and manufactures custom products (microcontroller boards to complete control systems) under customer brands as part of its ODM pillar.
3. Converter / Controller Units: Converts absocoder detector signals into binary, Gray code, pulse, network (EtherNet/IP, EtherCAT, PROFIBUS-DP, PROFINET, CC-Link, DeviceNet, SSI), or cam/limit switch output formats for PLC integration.
4. Renewal / Replacement Support: Provides replacement products for legacy systems (e.g., Omron cam positioner replacement), supporting existing installed base with backward-compatible upgrades.

Core offering

NSD Corporation designs, manufactures, and sells absolute position detection sensors and controllers based on its proprietary electromagnetic induction ABSOCODER technology. Its product lineup includes single-turn and multi-turn rotary encoders, linear displacement sensors, cylinder-integrated sensors, electronic cam and limit switch controllers, network-connected converters for major industrial fieldbus protocols, tension meters, magnet switches, and intrinsically safe explosion-protected encoders. The company also operates an ODM business building sensors under customer brands and a trading business sourcing complementary components.

Product overview

NSD manufactures industrial position detection sensors and associated converters/controllers under the ABSOCODER brand. The core system consists of a detector (sensor) unit and a converter/controller unit connected via proprietary analog signal cable. Detector types include: VRE single-turn rotary encoders, MRE multi-turn rotary encoders (up to 3,072 rotations), VLS linear encoders, Inrodsensor cylinder-built-in linear encoders, and CYLNUC actuator-encoder integrated cylinders. These are paired with converters that output binary/Gray code (NCV, NCX series), pulse signals (PULPUL, NP Scale), or connect directly to industrial networks (EtherNet/IP, EtherCAT, PROFIBUS-DP, PROFINET, CC-Link, DeviceNet, etc.). Separate controller products include VARICAM electronic cam switch controllers (replacing mechanical cam switches), VARILIMIT multi-point limit switch controllers, and VS-12PB positioning controllers. The ezABSO electromagnetic induction rotary encoder series provides non-contact rotary encoding with pulse or network output. Supplementary products include magnet switches (ABSO PX), tension meters (SMARTTENSION), eddy current displacement sensors (EZ GAP), non-contact transmission devices (ABSOCOUPLER), slip rings, intrinsically safe explosion-protected products, and renewal/custom engineering services. NSD also operates as an ODM (producing customer-brand products) and trading company (proposing third-party products), alongside its core manufacturing business.
