Single-axis inclinometer WCA300M

TTLMEMSIP67

Product Overview
The RION WCA300M is a single-axis inclination (tilt) module designed for industrial embedding and SMT placement. It integrates a micro-mechanical sensing unit with an anti‑jamming platform for stable long-term operation across a wide temperature range. Modules undergo factory calibration to minimize zero-bias, cross-axis and linearity errors. Tape packaging enables direct automatic placement with SMT machines.
