Single-axis tilt sensor NTS3

analogvoltage outputMEMS

Product Introduction
The NTS3 series is a compact, cost-effective single-axis tilt sensor designed for industrial applications requiring limited installation space and strict cost control. It provides an analog voltage output (0–5V) with a 2.5V zero at 0° after internal linearity correction. The sensor integrates a MEMS-based tilt sensing unit for low power consumption, consistent performance and wide operating temperature range (-40°C to +85°C).

The NTS3 uses a non-contact measurement principle and delivers real-time tilt angle output. Its compact footprint and strong resistance to electromagnetic interference, shock and vibration make it suitable for industrial equipment, platform attitude measurement and both static and slow dynamic angle monitoring in harsh environments.

Key features

• Output: 0–5V (zero output at 0° = 2.5V)

• Selectable measurement ranges: ±30°, ±60°, ±90°, 0–360°
• Ingress protection: IP67; operating temperature: -40°C to +85°C
