Miniature self-contained photoelectric sensors in universal housing
• Easily fits (or retrofits) almost any mounting situation
• Exceptional optical performance, comparable to larger “MINI-style” or barrel
sensors
• 10 to 30 V dc operation, with complementary (SPDT) NPN or PNP outputs,
depending on model
• Bright LED operating status indicators are visible from 360°
• Rugged sealed housing, protected circuitry
• Models available with or without 18 mm threaded “nose”
• Less than 1 millisecond output response for excellent sensing repeatability
• Choose 2 m (6.5 ft) or 9 m (30 ft) cable or 150 mm (6 inch) Pico-style pigtail QD
To order the 9 m (30 ft) cable model, add suffix "W/30" to the cabled model number.
QD Models. For 4-pin integral Euro-style QD, add suffix “Q8” (e.g., QS186EQ8). For 4-pin
integral Pico-style QD, add suffix “Q7” (e.g., QS186EQ7). For 4-pin 150 mm (6") Eurostyle pigtail, add suffix “Q5” (e.g., QS186EQ5). For 4-pin 150 mm (6") Pico-style pigtail,
add suffix “Q” (e.g., QS186EQ).

WARNING: Not To Be Used for Personnel Protection
Never use this device as a sensing device for personnel protection. Doing so could lead to
serious injury or death. This device does not include the self-checking redundant circuitry necessary
to allow its use in personnel safety applications. A sensor failure or malfunction can cause either an
energized or de-energized sensor output condition.

Installing Fibers
Cutting Unterminated Plastic Fibers QS18V..6FP
Unterminated plastic fibers are designed to be cut by the user to the length required for the application.
To facilitate cutting, a Banner model PFC-1 cutting device is supplied with the fiber. Cut the fiber as follows:
Use small ports for fiber sizes:
• 0.25 mm (0.01 inches)
• 0.5 mm (0.02 inches)
Use large ports for fiber sizes:
• 0.75 mm (0.03 inches)
• 1.0 mm (0.04 inches)
• 1.5 mm (0.06 inches)
Figure 1. PFC-1 Cutting Device
1. Locate the control end of the fiber (the unfinished end).
2. Determine the length of fiber required for the application. If using a bifurcated fiber, separate the two halves of the
fiber at least 51 mm (2 inches) beyond the fiber cutting location.
3. Lift the top (blade) of the cutter to open the cutting ports.
4. Insert one of the control ends through one of the cutting ports on the cutter so that the excess fiber protrudes from the
back of the cutter.
5. Double-check the fiber length, and close the cutter until the fiber is cut.
6. Using a different cutting port, cut the second control end to the required length.
NOTE: To ensure a clean cut each time, do not use a cutting port more than once.
7. Gently wipe the cut ends of the fiber with a clean, dry cloth to remove any contamination. Do not use solvents or
abrasives on any exposed optical fiber.
Installing Plastic Fibers QS18V..6FP
Follow these steps to install the plastic fibers.
Figure 2. Installing Plastic Fibers
1. Slide the fiber gripper up to unlock it (A).
2. If using 0.25 mm or 0.5 mm core fibers, slide the plastic fiber adapters onto the fibers, flush with the fiber ends.
3. Carefully insert the prepared plastic fiber ends into the ports (B) as far as possible without applying extra force.
4. Slide the fiber gripper down to lock the fibers in place (C).
1. Slide the supplied o-ring on the sensor end of the fibers, as shown.
2. Press the fiber ends firmly into the ports located on the front of the sensor.
3. Slide the supplied u-shaped retaining clip into the slot in the sensor’s barrel until the clip snaps into place.
