SL0 Series Slot Sensor Overview
The SL0 Series Slot Sensor (sometimes called a “Fork Sensor”) com-
prises an opposed-mode emitter and its receiver inside a single con-
venient housing. Opposed-mode sensing is very reliable, and the sin-
gle 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.
Using the SL0 Series Slot Sensor
Light/Dark Operate Select
Selecting Light or Dark Operate is a simple procedure: connect the
gray wire (see hookups, page 3), to +V (10-30V dc) for Dark Operate, and to dc com-
mon (or open) for Light Operate.
LED Indicators
The Slot Sensor features two LED Indicators: Power (green) and Signal (yellow). They
indicate the following:
Green ON steady: Power ON
Yellow ON steady: Sensor sees light
Yellow flashing: Excess gain is marginal (1 to 1.5x) in light condition
