High-Precision Sensing Solutions — Engineered for Motion Control
OTV Sensing designs and manufactures magnetic encoder rings, off-axis absolute encoders, and modular linear magnetic scales for robotics, servo motors, and industrial automation. ISO-certified factory with global delivery.
Trusted by Robotics & Automation Companies Worldwide
What We Make
From standard encoder targets to fully custom sensing modules — one partner, full traceability.
Encoder Ring / Magnetic Target
1-track incremental & 2-track Nonius absolute encoder discs. Custom pole counts, radial or axial magnetization. Compatible with iC-Haus, RLS, and major encoder IC platforms.
Browse Encoder Rings →Sensor / Encoder Module
Hollow-shaft off-axis encoders, modular linear magnetic encoders (0.5 µm resolution), and absolute inductive encoders (15–22 bit). SSi, BiSS-C, RS-422, ABZ output.
Explore Encoder Modules →Hard Ferrite Rings & Components
Multi-pole hard ferrite magnet rings (-40°C to 250°C, low eddy current loss). Precision bushings, PIN pins & gears in high-strength POM, PTFE & PEEK.

Three reasons we win repeat business from industrial automation teams.
① Custom by Design, Not by Compromise
You specify the dimensions, pole count, pole width, magnetization pattern (radial or axial), and mounting features — we deliver custom encoder rings and modules that drop into your mechanical stack-up. In-house R&D covers magnetic materials, Hall-effect and inductive sensing, and wireless transmission — so we optimize across the full signal chain.
② Full-Chain Manufacturing, One Factory
SMT assembly, sensor packaging, calibration, and final testing — all under one roof. Vertical integration ensures batch-to-batch consistency, eliminates subcontractor handoffs, and lets us turn urgent custom orders in days rather than weeks.
③ 100% Tested Before It Leaves
Every magnetic ring, magnetic scale, and encoder module is individually tested for performance before shipment. We provide batch-level test reports with full traceability. No sampling — every unit is verified against its spec.
