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.
Figure 2 Magnetic Sensor to Amplifier Connection Detail
When using the MT-190W with any
Monarch instrument, refer to the instrument instruction manual for sensor
connection detail.
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.

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.
