Why Engineers Choose OTV

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.
