WARNING . . .
Not To Be Used for Personnel Protection
Never use these products as sensing devices for personnel protection. Doing so could lead to serious injury or death.
These sensors do NOT include the self-checking redundant circuitry necessary to allow their use in personnel safety applications. A
sensor failure or malfunction can cause either an energized or de-energized sensor output condition. Consult your current Banner
Safety Products catalog for safety products which meet OSHA, ANSI and IEC standards for personnel protection.

SL Series Slot Sensor
Overview
The SL Series Slot Sensor (sometimes called a “Fork Sensor”) comprises an opposed-mode
emitter and its receiver inside a single convenient housing. Opposed-mode sensing is very
reliable, and the single self-contained housing provides easy installation, with no sensor
alignment required. In addition, the molded-in arrow on the emitter portion of the housing and
the slotted design on the receiver portion of the housing show at a glance the position of the
beam, simplifying installation placement.

Sensitivity Adjustment
The sensor’s sensitivity is adjusted by turning the 4-turn clutched Sensitivity potentiometer
withasmallslottedscrewdriver.Applypowertothesensorand:
1. Set the potentiometer to minimum sensitivity (fully counter-clockwise) and present
the Light condition. If the yellow Signal Condition indicator is ON, that is your Light
condition sensitivity position. If not, proceed to step 2.
2. Turn the potentiometer clockwise, just until the yellow Signal Condition indicator comes
ON; note its position.
3. Present the Dark condition and turn the potentiometer clockwise, just until the yellow
Signal Condition indicator comes ON; note its position.
4. For maximum reliability, the difference between these two positions should be at least
one full turn. Set your sensitivity midway between the two positions for best sensing
results.
If the object to be sensed is very thin and non-metallic, the sensor may emit too much light
energy for the object to completely block the beam. To test this, place the object in the
sensing position, and decrease the sensitivity until the yellow LED goes OFF. Remove the
object; verify that the indicator comes ON solidly. If this does not occur, investigate other
sensing alternatives.
