Sensitivity Adjustment
The sensor’s sensitivity is adjusted by turning the 270-degree-turn Sensitivity
potentiometer with a small flat-blade screwdriver. Apply power to the sensor and turn the
potentiometer all the way clockwise (max. gain). If the object to be sensed does not block
the beam at max. gain, turn the gain down a little at a time, testing with the object, until
the object can be sensed with reliability.
If adjusting the sensitivity with the potentiometer does not provide reliable object
detection, investigate alternative sensing methods.
Light/Dark Operate Select
Select Dark Operate (D.O.) or Light Operate (L.O.) by turning the DO/LO selector switch
to the desired setting using a small flat-blade screwdriver. If D.O. is selected, the output
conducts when the receiver element does not see the emitted light (object is present). If
L.O. is selected, the output conducts when the receiver element sees the emitted light
(object is absent).

The SLM 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, molded-in arrows on the housing show at a
glance the position of the beam, simplifying installation placement.
Applications include counting, gear tooth detection, edge detection, part sensing on
conveyor rails and belts, position and orientation verification, dimension verification,
tool break monitoring, and level monitoring.
