Single-axis tilt sensor STS

XYRS-485RS-232

Product Introduction
The STS standard output tilt sensor from RUICOM Technology is engineered for industrial automation measurement. It integrates a high-performance MEMS tilt unit with a 24-bit differential A/D converter and a fifth-order digital filter to deliver precise measurements of roll and pitch in a compact industrial housing. Available with TTL, RS232 or RS485 outputs and MODBUS RTU option, the STS is designed for reliable field operation with IP67 protection.

Key Features

• Single- or dual-axis tilt measurement (X / XY)
• Extra-wide measurement range up to ±180°
• High accuracy across ranges (down to 0.01° full-scale)
• Industrial-grade design with IP67 sealing
