ROLS - Remote Optical Laser Sensor
SAFEGUARDS AND PRECAUTIONS:
WARNING – Class 2 laser product – This product emits a visible beam of
laser light. Avoid exposure to the laser radiation. The use of optical viewing
aids (binoculars, for example) may increase the ocular hazard.
CAUTION – The laser beam should not be intentionally aimed at people or
animals.
CAUTION – Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous radiation exposure.
Read and follow all instructions in this instruction sheet carefully, and retain this sheet for future reference.
Do not use this instrument in any manner inconsistent with these operating instructions or under any
conditions that exceed the environmental specifications stated.
This instrument is not user serviceable. For technical assistance, contact the sales organization from
which you purchased the product.
DESCRIPTION:
The Remote Optical Laser Sensor has a visible red laser light source and green
LED on-target indicator. The class 2 laser source acts as the aiming device during
setup and can accurately measure speeds from 1-250,000 RPM from a distance of
up to 25 feet with a maximum offset angle of 60 degrees from the rotating object.
The sensor is housed in a threaded 303 stainless steel tube and supplied with a 90
degree mounting bracket, jam nuts and an eight foot shielded cable. ROLS-P comes
with a 3.5mm (1/8”) male stereo plug adapter. ROLS-W comes with 4 tinned wires.

The ROLS Remote Optical Laser Sensor is capable of detecting a reflected pulse from a target consisting of T-5 Reflective Tape or high contrast
color differences (such as black and white) at distances up to 25 feet [7.6 m] from the rotating object and angles up to 60 degrees. For most
applications, a ½” [12 mm] square piece of Reflective Tape (T-5) should be applied to a clean area on the rotating object. At slow speeds (<500
RPM) best results will be obtained by aiming the laser perpendicular (90°) to the target using a narrow piece of reflective tape – typically 0.2 inch
(5 mm) wide.
The ROLS should be mounted (using the supplied jam nuts and aluminum mounting bracket) and optically aligned to illuminate the on-target
indicator once per revolution. It is recommended that the optical sensor be placed at a slight angle (15 degrees) from perpendicular, so that the
sensor will receive only pulses from the reflective marker. Triggering from contrasting colors should be done perpendicular to the target. The
ROLS should be at least 1 inch from the reflective target to avoid false triggering. The green LED On-Target Indicator will blink at the input
frequency rate when the ROLS is properly aimed. NOTE: The green LED On-Target Indicator will blink on and off at slow speeds and remain on
steady at high speeds.
The ROLS is supplied with a 3.5 mm [1/8 inch] male stereo plug (ROLS-P) or an 8 foot [2.4 m] cable terminated with 4 tinned wires (ROLS-W).
The plug may be cut from the cable and the leads stripped and connected as shown in connection detail for tinned wire above. An optional 25 foot
[7.6 mm] extension cable EC-25P is available with a female socket for the plug on one end, and a 3.5 mm [1/8 inch] male stereo plug on the other
(for ROLS-P).
The ROLS-P will work directly with all Monarch handheld tachometers and Nova-Strobe dax, dbx, and pbx Stroboscopes. The ROLS-W will work
with all Monarch panel instruments that accept pulse inputs (e.g. ACT Series, DataChart 1250, DataChart 6000) and vibration data collectors. A
sensor power supply (SPSR-IM) with BNC output is available for those applications that require a separate power source for the sensor.
