SAFEGUARDS AND PRECAUTIONS
Laser Hazards:
Eye injury from beam - Do not look into the direct or reected beam; can cause eye
injury up to 25  [7.5 m] away.
Visual interference (glare) with pilots and drivers - Interferes with vision up to 525
 (160 m) away. Can be a distracon up to 1 mile [1.6 km] away. NEVER point any
laser towards aircra or vehicles; it is unsafe and illegal.
Read and follow all instrucons in this manual carefully, and retain this
manual for future reference.
Do not use this instrument in any manner inconsistent with these operang
instrucons or under any condions that exceed the environmental specicaons
stated.
This instrument is not user serviceable. For technical assistance, contact the sales
organizaon from which you purchased the product.

1.0 OVERVIEW
The RLS and RLS24 Rugged Laser Sensors are opcal reecve sensors
with a visible red laser light source and green LED on-target indicator. The
sensors are rated IP67 and are designed to survive accidental exposure to
water, dirt, oil, and other contaminants.
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 oset angle of 60 degrees from the rotang
object. The sensors are housed in an M20x1.5 threaded 316L stainless steel
tube and have a waterght M12 4 pin socket on the backend. A 90-degree
mounng bracket and 2 jam nuts are provided for mounng.
The RLS and RLS24 are supplied with a removable 3 m [9.8 .] cable with
a waterght M12 4 Pole Female connector on one end and a 3.5 mm [1/8
inch] male stereo plug (RLS-P or RLS24-P) or 4 nned wires (RLS-W or
RLS24-W) on the other end. An oponal 25 . [7.6 m] 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 RLS-P or RLS24-P).
The sensor can be powered by 4-15 V dc or 10-24 V dc and is available in
the following conguraons:
Model Power Requirement Removable 3 m Cable
RLS-P 4 – 15 V dc ±20% 0.5W M12 4 Pole Female connector to
1/8 in. [3.5 mm] male stereo plug
RLS-W 4 – 15 V dc ±20% 0.5W M12 4 Pole Female connector to
nned wires
RLS24-P 10 – 24 V dc ±20% 0.5W M12 4 Pole Female connector to
1/8 in. [3.5 mm] male stereo plug
RLS24-W 10 – 24 V dc ±20% 0.5W M12 4 Pole Female connector to
nned wires

2.0 CONNECTION DETAILS
Connecon to the sensor is via the waterght M12 connector on the end
of the sensor. The sensor may be ordered with one of two cables: the -P
with a 3.5 mm stereo connector or the -W with nned wires as shown
below.

3.0 OPERATING INSTRUCTIONS
Plug the sensor into an appropriate power source (RLS = 4-15 V dc,
RLS24 = 10-24 V dc). The RLS-P will work directly with all Monarch
handheld tachometers and stroboscopes that accept pulse input through
an input jack (e.g., PLT200, PLS, dax, dbx, DBL, pbx, PBL, Nova-Pro® 300,
Nova-Pro® 500). The RLS-W and RLS24-W will work with all Monarch panel
instruments that accept pulse inputs (e.g., ACT series, Frequency to Analog
Converters, DataChart™ 1250, DataChart™ 6000) and vibraon data
collectors. A sensor power supply (SPSR-IM) with BNC output is available
for those applicaons that require a separate power source for the sensor
(RLS-P only).
The RLS Rugged Laser Sensor can detect a reected pulse from a target
consisng of T-5 Reecve Tape or high-contrast color dierences (such
as black and white) at distances up to 25 feet [7.6 m] from the rotang
object and angles up to 60 degrees. For most applicaons, a ½" [12 mm]
square piece of T-5 Reecve Tape should be applied to a clean area on
the rotang object as a target. At slow speeds (<500 RPM) best results will
be obtained by aiming the laser perpendicular (90°) to the target using a
narrow piece of reecve tape – typically 0.2 inch [5 mm] wide.

4
The RLS should be opcally aligned to illuminate the On-Target Indicator
once per revoluon. It is recommended that the opcal sensor be placed
at a slight angle (15 degrees) from perpendicular so that the sensor will
receive only pulses from the reecve marker. Triggering from contrasng
colors should be done perpendicular to the target. The RLS should be at
least 1 inch from the reecve target to avoid false triggering. The green
LED On-Target Indicator will blink at the input frequency rate when the RLS
is properly aimed.
Note: The green LED On-Target Indicator will blink (on/o) at slow speeds
and remain on steady at high speeds.
Note: Opcal speed sensors require environments that are clean and free
of mist, steam, dirt, oil, and other contaminants to funcon properly. The
RLS can survive these condions, but it will not funcon properly if the
opcs are contaminated. Carefully cleaning or drying the opcs will restore
normal operaon.
