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.

OVERVIEW:
The MT-190 Magnetic Amplifier Module enhances the performance of the M-190W Magnetic Sensor (see other side). The Amplifier
extends the operating gap for the sensor to 0.25 inches [6.35 mm] from the ferrous target. The MT-190 Magnetic Trigger Sensor with
Amplifier can sense gear teeth, bolt heads or shaft keys. The MT-190 provides a pulsed output signal and is TTL compatible with 5 Vdc
supplied.
The M-190W Magnetic Sensor is combined with an Amplifier Module to become an MT-190P or MT-190W. The Amplifier Module has an
8 foot [2.438 m] cable with 3 tinned wires and a ground shield (MT-190W) or 1/8 [3.5 mm] phone plug (MT-190P) termination.
The MT-190W is compatible with all Monarch ACT Series panel tachometers and Data-Chart 1250 Paperless Recorders.
The MT-190P is compatible with the following Monarch instruments: Pocket Laser Tachometer 200 (PLT200), SPSR Self-Powered
Sensor, Deluxe Nova-Strobes (dax, dbx, DBL) and Phaser-Strobes (pbx, PBL).
The MT-190W and MT-190P can also output pulses to a user’s data acquisition system.
CONNECTION DETAIL:
The Magnetic Sensor must be
connected to the Magnetic Trigger
Amplifier Module. Refer to Figure
2 for connection detail. The
connection details for the Amplifier
Module are shown below Figure 2.

When using the MT-190P with any Monarch instrument, plug the 1/8 [3.5
mm] phone plug into the input jack on the respective instrument.
OPERATION:
Magnetic sensors convert motion of a ferrous target into an AC voltage
output proportional to speed. The Amplifier Module amplifies the signal
and converts it to square wave pulses. 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.
