DSO Series Gear Tooth Speed Sensor
The DSO series delivers dynamic, non-contact speed sensing for ferrous targets with near-zero speed detection and long-term reliability. Powered by Hall effect technology, these solid-state sensors feature internal hysteresis, bounce-free operation, and temperature stability, making them ideal for harsh industrial and mobile environments.
Designed to track gear teeth, bolt heads, and other magnetic targets, the DSO series outputs a clean digital square wave pulse for accurate speed or count feedback. With self-calibrating performance and flexible mounting options, these sensors are easy to install and built to last.
The DSO series is available in a wide range of housings and electrical configurations, including NPN, PNP, TTL, and EMI-protected options, to meet the needs of innovators across automotive, agricultural, and manufacturing sectors.
