  8. TT Electronics OPTEK - OPB848 - Slotted Optical Switch NEW
    Special Price $3.98 Regular Price $8.75

    TT Electronics -Optoswitch OPB848  Optical Switch 2.54mm Slot, 1.52mm Aperture, Through hole Optocoupler Output Type:Transistor Leaded Process Compatible:Yes Voltage Rating:30V RoHS Compliant: Yes TARN NEW 

    OPB848 consists of a gallium aluminum arsenide LED and a silicon phototransistor, which is
    soldered into a printed PCBoard and mounted in a high-temperature plastic housing on opposite sides of a 0.100 inch (2.540 mm) wide slot. Device has a .025 (0.635mm) inch by .060 inch (1.524 mm) aperture in front of the phototransistor for high resolution positioning sensing. Phototransistor switching takes place when an opaque object passes through the slot.

    Applications:
    • Non-contact interruptive object sensing
    • Assembly line automation
    • Machine automation
    • Equipment security
    • Machine safety
