Inductive Sensors
The new GE200 HP is 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 GE200 HP must be connected to the Monarch amplifier module which provides input power and a TTL pulse output.

Infrared Sensor
1-999,990 RPM. Both the IRS-5P and IRS-5W are proven to be reliable high speed sensors. With a working range of 12 to 25 mm from very high speed equipment or an application providing contrasting light and dark surfaces.

Magnetic Sensors
1-99,999 RPM. Self-powered gear sensor. M-190W and M190P are very popular magnetic sensors commonly used with 60 tooth 20 pitch gears. The sensors mount with 0.005 inches (0.127mm) of a 0.1 inch (2.5mm) target. These sensors require no power from our display modules as they self-generate an AC signal.

Magnetic Sensor with Amplifier Module
1-99,999 RPM. Same as the M-190 sensors but with an enhanced performance from the amplifier The amplifier extends the operating gap to 0.25 inches (6.35mm) from the target. Frequently used on gears The MT-190 and MT-190W provide a 0-5V TTL output signal.

Laser Sensor
1-150,000 RPM. The Ultimate speed sensor. The RLS-5P and RLS-5W operate up to 50 feet (1.5m) at 75 from a reflective target. In some applications at close range contrasting colors can trigger the sensor. Adjustable sensitivity provides dynamic fine tuning of sensor response.

Optical Sensors
1-250,000 RPM. The most versatile and popular sensors we make. The ROS-5W, ROS-5P and ROS-9P are threaded stainless steel remote optical sensors with a visible red LED light source. All these sensors have the "on-target" green LED indicator.
