Target positioning
To ensure reliable sensing performance, it is recommended to follow
the general guidelines regarding target positioning below.
•
Axial (head on) approach
— The target must be positioned so
that a projection of the target on the sensor face is centered
over the indicator area shown on the sensor face. If the target is
smaller than the indicator area, its axis should coincide with the
sensor axis.
•
Lateral (side, slide-by) approach
— Position the target at a
distance normally 50% of the rated axial sensing distance from
the sensor face.
Protection features
Built-in overload and short-circuit protection prevents damage to
sensors when the load current exceeds a safe level, and DC models
are additionally protected against reverse polarity. Protection levels
are shown in the specification table in this manual. For sensor
versions with LEDs, the LED indicator will flash if the overload or
short condition persists, and the cycle will repeat until the load current
returns or is corrected to a value below the protection threshold.
Wiring diagrams
Sensors should be mounted using four 3/8-inch bolts through the
mounting holes provided.
