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.
CONNECTION DETAIL:
When using the M-190W with an ACT-2A, ACT-3A, or ACT-3, refer to Figure
2A for sensor connection detail.
When using the M-190W with an ACT-1B, refer to Figure 2B 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.
