Overview
The SL30 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.
