Laser Switch Sensors
Miniature laser diffuse and through-beam switches from M3 housings, visible red spot.
Select a Laser Switching Layout and Mechanical Package
Laser switches provide a switching result; they are not automatically displacement gauges or safety scanners. Choose one-sided diffuse detection or an opposed emitter/receiver arrangement according to target access, then compare spot size, working gap, housing and electrical output for the actual model.

Compare the Configuration Paths
| Required task | Existing product page | What to confirm |
|---|---|---|
| Small one-sided mounting | DDSK miniature diffuse family | Compare body size, usable range on the target and cable exit. |
| Opposed emitter and receiver | DS miniature through-beam pairs | Confirm both mounting positions and whether both halves are included. |
| Right-angle mechanical access | DS right-angle pair options | Check beam orientation and available bracket space. |
Laser-Switch Configuration Checklist
| Purchase input | Information to provide |
|---|---|
| Optical access | Describe target colour, transparency, background and available powered mounting sides. |
| Small-feature detection | Provide the minimum feature and actual distance; a small visible spot alone is not a verified detection specification. |
| Electrical and laser instructions | Confirm the selected output and follow the exact product’s laser classification and handling instructions. |
For distance-selective background rejection compare photoelectric BGS options; for a numerical displacement result compare laser displacement sensors.
Send the application details and required configuration through the inquiry form so that the quotation identifies the selected equipment and options.
