Monarch Remote Sensors

Monarch remote sensors are available in a number of models that are compatible with their lines of tachometers and stroboscopes. Before ordering, check the datasheets to ensure specific models are compatible.

Monarch ROS-W and ROS-P (Remote Optical Sensor):

The remote optical sensor is a versatile and popular sensor. It is constructed of threaded stainless steel and has a visible red LED light source and green LED ‘On Target' indicator. Performs over a wide speed range (1-250,000 RPM) and operating envelope. Modulated and High Temperature versions available (to 257°F). The remote optical sensor includes a mounting bracket, an 8' cable and 12" of reflective tape. It is available with a 1/8" phone plug connection or tinned wire leads.

• Common usage: Wide range of general purpose applications in relatively clean environments.
• Compatible with: Pocket Laser Tach 200 (requires phone plug connection), Palm Strobe X (requires phone plug connection and SPSR sensor interface), Phaser-Strobe PBX (requires phone plug connection), Nova-Strobe DBX (requires phone plug connection), ACT Series Panel Tachometers, F2A3X Signal Converter (ROS-W & ROS-HT-W-25)

Monarch M-190W or M-190P (Magnetic):

The magnetic sensor is the most popular sensor for use with 60 tooth 20 pitch gears. The magnetic sensor mounts within 0.005 inches (0.127 mm) of a minimum 0.1 inch (2.5 mm) target. This sensor requires no power from the display module and self generates an AC signal. The magnetic sensor is for speeds ranging from 1 to 99,999 RPM. The magnetic sensor includes an 8' cable and is available with a 1/8" phone plug connection or tinned wire leads.

• Common usage: Ferrous metals, primarily gear teeth.
• Compatible with: ACT Series Panel Tachometers

Monarch MT-190W or MT-190P (Magnetic with Amplifier Module):

This sensor combines a standard magnetic sensor with an amplifier for improved performance. The amplifier extends operating gap to 0.25 inches (6.35 mm) from the target. It is frequently used on gears as the M-190, but can also sense bolt heads or shaft keys and provides a 0-5V TTL output signal. The magnetic sensor with amplifier is for speeds between 1 and 99,999 RPM and includes the sensor, amplifier and 8' of cable. It is available with a 1/8" phone plug connection or tinned wire leads.

• Common usage: Ferrous metals including bolt heads or shaft keys in addition to gear teeth.
• Compatible with: Pocket Laser Tach 200 (requires phone plug connection), Palm Strobe X (requires phone plug connection and SPSR sensor interface), Phaser-Strobe PBX (requires phone plug connection), Nova-Strobe DBX (requires phone plug connection), ACT Series Panel Tachometers, F2A3X Signal Converter (MT190-W)

Monarch PS-12 or P5-11 (Proximity):

The PS-12 proximity sensor is a three wire threaded IP67 metal sensor outputs an open collector PNP pulse. Operates at a 0.15 inch (4mm) gap with a .45 inch (12mm)target. Includes red LED on target indicator.

The P5-11 proximity sensor is a two wire probe style inductive sensor for use up to 0.2 inches (5 mm) from 0.5 inch (12 mm) metallic target such as bolt head or shaft locking key. It can measure speeds from 1 to 60,000 RPM. It includes a 6' cable.

• Common usage: Permanent installation in harsh industrial environments.
• Compatible with: ACT Series Panel Tachometers

Monarch IRS-W or IRS-P (Infrared):

The infrared sensor is the ideal sensor for working 0.5 to 1.0 inch (12 to 25mm) from high speed equipment or other applications providing only contrasting light and dark surfaces or beam interruption by solid objects. It is capable of speeds from 1 to 999,999 RPM. The infrared sensor includes a mounting bracket, 8' of cable and is available with a 1/8" phone plug connection or tinned wire leads.

• Common usage: Dentist and other high speed drills, slots or gear teeth. Does not require reflective tape.
• Compatible with: Pocket Laser Tach 200 (requires phone plug connection), Palm Strobe X (requires phone plug connection and SPSR sensor interface), Phaser-Strobe PBX (requires phone plug connection), Nova-Strobe DBX (requires phone plug connection), ACT Series Panel Tachometers, F2A3X Signal Converter (IRS-W)

Monarch GE-200 (Inductive):

A non-contact electromagnetic inductive sensor designed for making RPM measurements on gasoline engines. The sensor will detect the high voltage flux field being induced from ignition coils or magnetos on 2 or 4 cycle gasoline engines. The sensor will detect the electromagnetic flux field through metal engine covers.The GE200 HP must be connected to the Monarch amplifier module which provides input power and a TTL pulse output. The GE200 HP includes an integral 15 foot (5m) cable and can be mounted up to 12 inches (30 cm) away from the ignition coil or magneto. To find the optimal mounting position, simply move the sensor around the high voltage flux source until the display on your tachometer indicates a steady RPM reading.

• Common usage: 2-cycle and 4-cycle gasoline engines
• Compatible with: ACT Series Panel Tachometers
