DSO Series | Gear Tooth Speed Sensor
Achieving dynamic non-contact speed detection! DSO series providing long-term reliability | Gear tooth speed sensor
The "DSO Series" is a gear tooth speed sensor that achieves dynamic non-contact speed detection against iron-based targets, providing detection from nearly zero speed and long-term reliability. It is a solid-state sensor that employs Hall effect technology, featuring operation without internal hysteresis or chattering, and temperature stability, making it suitable for harsh industrial applications and mobile environments. Designed for tracking gear teeth, bolt heads, and other magnetic targets, this product outputs clean digital rectangular wave pulses that correspond to accurate speed and count feedback. 【Features】 ■ Detection at nearly zero speed for precise low-speed monitoring ■ Long-term reliability due to solid-state Hall effect design with no moving parts ■ Self-calibrating output responds to both rising and falling edges of iron-based targets ■ Wide detection range for magnetic targets such as gear teeth and bolt heads ■ Bounce-free operation and clean signal output due to internal hysteresis ■ Temperature stability performance across harsh environments *For more details, please download the PDF or feel free to contact us.
