Optek Screw Slotted Optical Switch, Buffer, Open Collector with 10K Pull Up Resistor Output

This family of Photologic® slotted optical switches, from Optek Technology, offer you various options enabling design flexibility. This flexibility includes choices of slot width, aperture, shell material, mounting configurations and lead spacing, or wires. An opaque plastic housing minimises the sensitivity to visible and near IR light.
The parallel faces inside the slot are covered with an IR transmissive plastic or opaque plastic with an opening. The IR transmissive plastic is suitable for applications which require dust protection and the opaque is for applications that require maximum protection against ambient light.
Suitable applications for the slotted optical switches include; mechanical switch replacement, speed indication, mechanical limit indication and edge sensing.
