Product Overview

The LS-Compact-25 Miniature Linear Encoder Sensor is a high-precision, space-constrained position sensing solution engineered for demanding industrial and embedded applications. As a true miniature linear sensor, it delivers exceptional accuracy across its full 0–25 mm measurement range — making it ideal for compact motion control systems where every millimeter counts. This linear encoder integrates seamlessly into PCB-based designs thanks to its standardized surface-mount footprint and low-profile housing. With an impressive resolution of 1 µm and robust IP67 ingress protection, the LS-Compact-25 maintains reliable performance in harsh environments — including dust, moisture, and vibration-prone settings. It serves as a high-fidelity 25mm position sensor for closed-loop feedback, offering analog (0–10 V) and digital (SPI) output options for flexible system integration.

Designed specifically for OEMs and automation integrators, this PCB mount sensor eliminates mechanical complexity associated with traditional optical or magnetic encoders — delivering plug-and-play repeatability without recalibration. Its miniature form factor (28 × 12 × 8 mm) and lightweight construction support miniaturized robotics, medical devices, precision actuators, and semiconductor handling equipment.
