The M-190W Magnetic Sensor is a rugged, high performance self-powered magnetic pickup sensor primarily used for measuring speed using gear teeth, but bolt heads, slots or keys also work. The sensor mounts within 0.005 inches [0.127 mm] of a minimum 0.1 inch [2.5 mm] diameter ferrous target. The sensor self-generates an AC signal and requires no power from any display module. The M-190W has a 10 ft.[3 m] shielded cable terminated with tinned wires.
The M-190W Magnetic Sensor is compatible with all Monarch ACT Series Panel Tachometers, F2A1X Frequency to Analog Converter/Tachometer, and MT-190 Magnetic Trigger Amplifier Modules.
