The Monarch SPSR-IM Interface Module translates the signal of the sensor into a compatible TTL Pulse. This TTL Pulse is determined by the target object, and it can be positive 0-5V or negative 5-0V, determined by the user. The output signal is provided through a BNC cable.

The SPSR-IM Interface Module also powers the sensors, although it must be powered itself. The sensors connect to the unit through a phono jack. Sensors that have a phono plug are identified by the "P" at the end of the part number. Internally there are 4 "AA" NiCad batteries that run the unit. The SPSR-IM can be run continuously from a charger, or it will operate up to 7 hours on a full charge.

The SPSR-IM includes a universal 110/230 VAC charger/power supply. The unit can also be powered by 9-15 VDC. The SPSR-IM is now RoHS compliant and CE approved.

Optical Sensor - ROS-P	Infrared Sensor - IRS-P	Magnetic Sensor - MT-190-P with Amplifier Module
1-250,000 RPM. The most versatile and popular sensors we make. The ROS-5P is a threaded stainless steel remote optical sensor with a visible red LED light source. The sensor has an "on-target" green LED indicator.	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.	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.
