OVERVIEW:
The M-190W Magnetic Sensor is a self-powered gear sensor that is most popular for use with 60 tooth 20 pitch gears. The sensor mounts
within 0.005 inches [0.127 mm] of a minimum 0.106 inch [2.692 mm] diameter ferrous target. The sensor self-generates an AC signal and
requires no power from the display module.
The M-190W is compatible with all Monarch ACT Series panel tachometers and MT-190 Magnetic Trigger Sensor/Amplifier models.

When using the M-190W with any Monarch ACT Series panel tachometer, refer to the panel tachometer instruction manual for sensor
connection detail.
OPERATION:
Magnetic sensors convert motion of a ferrous target into an AC voltage output proportional to speed. The target must not be smaller than
the magnetic poll piece (0.106 inches, 2.692 mm) or larger than the diameter of the sensor (0.625 inches, 15.875 mm). Gear teeth are
preferred, but bolt heads, slots or keys also work. The Monarch ACT Series panel tachometers will typically operate from all 2-wire design
magnetic sensors. The stainless steel and waterproof housing of the M-190W sensor allow operation in harsh locations. The user can
increase the cable length up to a total of 500 feet [152.4 m] in length.
