MT-190W and MT-190P1-99,999 RPM. Self-powered gear sensor. M-190W Magnetic Sensor and M190P Magnetic Sensor are very popular magnetic sensors commonly used with 60 tooth 20 pitch gears. The sensors mount with 0.005 inches (0.127mm) of a 0.1 inch (2.5mm) target. These sensors require no power from our display modules as they self-generate an AC signal.
