Banner Engineering SL30VB6VY SL30 Self-Contained Slot Sensor, Slot, 30 mm, Visible Red Sensing Beam, 0.3 ms Response Time, Bi-Polar 1 NPN/1 PNP Output

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.
