Sensors seem to not only be getting more and more intelligent, but also smaller in size.
When Powelectrics first started selling ultrasonic sensors, the smallest available was an M30 housing. I remember being amazed when the M18 was launched, then the M12. This morning I was informed of the latest in the Disoric range of ultrasonics; an M8 housing.
The M8 sensor has an adjustable range of 20-80mm. A switching output can be programmed NPN or PNP and can be set as normally open or closed. A sensing window can also be programmed via an automatic teach in process. The housing is manufactured from stainless steel.
