THESE PRODUCTS ARE NOT DESIGNED, TESTED, OR RECOM-
MENDED FOR USE IN HUMAN SAFETY APPLICATIONS.
USE #4 MOUNTING HARDWARE ONLY! LARGER HARDWARE
WILL DAMAGE THE SENSOR AND MAY CREATE AN ELECTRI-
CAL SHOCK HAZARD. TIGHTEN THE HARDWARE JUST TO THE
SENSOR BODY SO THAT NO DEFLECTION OF THE BODY
OCCURS.
DURING INSTALLATION, CORRECT POWER CONNECTIONS
MUST BE MADE FIRST TO ENSURE FAIL-SAFE SHORT CIRCUIT
PROTECTION OF THE OUTPUTS. REFER TO THE WIRING
DIAGRAMS IN THIS MANUAL.
DO NOT USE TOOLS TO APPLY TORQUE DIRECTLY TO SENSOR
BODY. ALIGN SENSOR BY HAND BEFORE TIGHTENING
MOUNTING HARDWARE.
THE GAIN AND LIGHT/DARK ADJUSTMENT POTS ARE 3/4
TURN POTS. ANY RESISTANCE ENCOUNTERED WHILE
ADJUSTING THESE POTS INDICATES YOU HAVE REACHED THE
ADJUSTMENT LIMIT STOP. TURNING PAST THIS STOP WILL
DAMAGE THE SENSOR.
USE ONLY A SUITABLE ADJUSTMENT TOOL OR FLATBLADE
SCREWDRIVER WHEN TURNING ADJUSTMENT POTS. SHARP
OBJECTS CAN DAMAGE THE POT AND RESULT IN ELECTRICAL
SHOCK.
AC/DC CONNECTOR VERSION SENSORS ARE EQUIPPED WITH
AN AC-TYPE CONNECTOR. THE USE OF DC POWER WITH AC-
TYPE CONNECTORS MAY NOT CONFORM WITH ESTABLISHED
STANDARDS.
INTRODUCTION
Thru-beam sensors consist of a source and detector posi-
tioned on opposite sides of a detection zone. The source emits
infrared and visible red light, which is received by the detector.
The detector output switches when this beam of light is either
blocked (when set for dark operation), or completed (light
operation). Note that a wide beam source will not work with a

This manual covers both forward viewing and right angle
viewing models. Although the units differ in the location of the
lenses, the basic fundamentals of installation, setup, and
operation are nearly identical. The two types of sensors may be
intermixed with no change in optical performance.
MOUNTING
The Comet sensor features a threaded housing and includes
jam nuts and washers. This allows mounting into any 0.75 inch
hole, or a model 6161A-6501 “L” bracket. Use caution to avoid
cross-threading the jam nuts on the sensor body. Tighten nuts
to less than 4 N•m (36 in.-lbs. or 3 ft.-lbs.) torque to avoid
stripping threads.
A second mounting method is to use #4 hardware in the 0.125
inch diameter mounting holes in the flat sides of the sensor.
This is ideal for mounting the Comet against a wall, piece of
equipment, rail, mounting bracket, etc.
