SLE30 Expert Series Slot Sensor Overview
The SLE30 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.
Expert series sensors feature easy-to-use push-button programming,
performed in TEACH mode. TEACH-mode programming may be
performed using either the push button, or remotely, using a remote
switch or process controller. The programming determines whether
the sensor outputs will conduct in light or dark conditions, and defines
the light and dark conditions for the sensor in each application. The
remote switch also may be used to disable the programming push
button for security.
The Dynamic TEACH option provides a means for teaching a series of
conditions; the SLE30 monitors the sensing events and automatically
sets the threshold between light and dark conditions.
