Inductive Encoders for Reliable, Non‑Contact Position Measurement
Zettlex inductive encoders provide accurate, non-contact position measurement using advanced inductive technology. Instead of the bulky transformer coils found in traditional inductive sensors, Zettlex encoders use lightweight printed circuits. This enables compact, robust and maintenance‑free position sensors that deliver stable performance in demanding environments.
How Zettlex Inductive Encoders Work
Inductive encoders operate using electromagnetic fields rather than physical contact or optical components. With no bearings, glass discs or delicate parts, they offer long‑term reliability even in harsh conditions such as vibration, shock, dust, moisture or extreme temperatures.
- Non‑contact operation — No wear, no friction and no mechanical degradation over time.
- High accuracy and repeatability — Stable measurement unaffected by contamination or light conditions.
- Lightweight, compact construction — Printed circuit technology enables slim, low‑mass designs.
- Exceptional robustness — Resistant to shock, vibration, dirt, oil and humidity.
- Zero maintenance — No cleaning, lubrication or recalibration required.
- Reliable performance — Consistent, dependable measurement all day, every day.
Encoder Types and Capabilities
- Rotary inductive encoders — Precise angular measurement for motors, robotics and automation.
- Absolute inductive encoders — True position feedback without homing.
- Custom inductive encoder designs — Tailored geometries, mounting patterns and environmental protection for OEM applications.
Applications Across Industry
- Aerospace and defence systems
- Robotics and automation
- Medical equipment
- Industrial machinery

Why Choose Inductive Encoders Over Optical or Magnetic?
- Immune to dust, dirt, oil and condensation — No optical paths to block or lenses to clean.
- Unaffected by magnetic fields — Ideal for motors, generators and high‑EMI environments.
- No fragile components — No glass discs or delicate electronics.
- Stable accuracy — Consistent performance across temperature variations.
- Long service life — Non‑contact operation ensures durability and reliability.
Selecting the Right Zettlex Encoder
Choosing the correct encoder depends on several key factors:
- Measurement range — Required angular travel.
- Accuracy and resolution requirements.
- Environmental conditions — Temperature, vibration, contamination or humidity.
- Mounting constraints and available space.
- Integration with servo drives or control systems.
