Convergent Mode Alignment
Object
Low
Reflectivity
Background
The sensing energy of a convergent mode sensor is concentrated at the
specified focus point. Convergent mode sensors are less sensitive to
background reflections, compared with diffuse mode sensors. However,
if background reflections are a problem:
• Skew the sensor position at a 10° to 25° angle to eliminate
direct reflections from shiny background surfaces
• Reduce the reflectivity of the background by painting the
surface(s) flat-black, scuffing any shiny surface, or drilling a
large hole, directly opposite the sensor
• Reduce the Gain adjustment
Note:
• Light condition: sensor output is ON
when there is no object in the beam
• Dark condition: sensor output is ON
when there is an object in the beam
Glass Fiber Installation
O-ring
Retaining Clip
1. Install the O-ring (supplied with the fiber) on each fiber end, as shown in the
drawing.
2. While pressing the fiber ends firmly into the ports on the sensor front, slide the U-
shaped retaining clip (supplied with the sensor) into the slot in the sensor's barrel,
until it snaps into place.

Sensor Face
1. With supplied
fiber cutter, make a clean cut at the control ends of
fibers.
2. Unlock the fiber gripper as shown in the drawing.
3. Apply appropriate fiber adaptors to the fiber, if needed.
4. Gently insert the prepared fiber ends into the ports as far as they will
go.
5. Slide the fiber gripper back to lock, as shown in the drawing.
