    ITUWA - N-110-2 Resistive Neon OptoIsolator, Photoconductor, Photoresistor, or Vactrol. Resistive Opoto-Isolator (RO), also called photoresistive opto-isolator, or Vactrol. Analog opto-isolator or lamp-coupled photocell, is an optoelectronic device consisting of a source and detector of light, which are optically coupled and electrically isolated from each other. An Opto-Isolator is an electronic component that transfers electrical signals between two isolated circuits by using light. Opto-isolators prevent high voltages from affecting the system receiving the signal. Status: Discontinued, New Old Stock High Isolation Voltage Optocoupler Radial Leads, PCB Mount Also known or referred to as an Optical Coupler or Transistor Relay. Neon 2K Ohms ON, 10Meg Ohm OFF, Slow Decay. Resistance Slowly Increases after 110V (100KRes) Power Removed Case: Radial 4-lead upright, similar shape as a radial capacitor. Approximate Dimensions: 0.4” Diameter, 0.7” Height. Made in Japan – Rare - Difficult Component to Find. Similar VTL and Clairex CLM Series Applications include: TTL logic control of AC power, Direct relay substitutes for AC drive, Power line circuit Isolation. Learn More

    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
