Frequently Asked Questions
- I do not understand the IR LED power ratings
The following Hyperlink is to an application note that covers this topic.
- Can I use Cyanoacrylates (Crazy Glue, Super Glue, etc.) on your switches?
No, only use epoxy adhesives on our products.
- How much torque should I use to fasten down a switch?
3 to 4 lb-in.
- What kind of plastics are OPTEK's switch housings made of?
The materials most commonly used are polycarbonate and polysulfone.
- How do I select a slotted optical switch?
Design considerations of speed, resolution, length of optical path, environment, performance, and cost impinge upon the proper selection of interruptive assemblies. OPTEK offers a wide selection of assemblies to meet design requirements. OPTEK’s slotted optical switches feature the following options.
- Phototransistor (OPB380 Series) or Photologic (OPB480 Series) output
- Gallium arsenide or gallium aluminum arsenide IR LEDs
- Dual channel encoder devices (OPB822) in side-by-side or over-under configurations for speed, direction or movement, and relative position sensing
- Various slot widths and depths
- Different aperture widths in front of the sensor and emitter
- Different mounting configurations
- How do I get technical assistance?
