Captron SENSORswitches from AutomationDirect, Cumming, GA, are capacitive pushbuttons that can be activated without pressure from hands or other parts of the body. They have a determinate sensing distance, which can be altered by varying the approach speed and/or damping factor.
According to the manufacturer, a quickly approaching finger will achieve a higher sensing distance than a slowly approaching finger. A hand, with its larger damping surface, will achieve a greater sensing distance than a finger at the same speed.
Easily installed with M8 connections, these switches use touch control with no mechanical pressure required and offer visual touch feedback through LED signals. They’re IP69K rated and shock-resistant, vandal-proof, and 100% water/oil-proof.
Offered in 22mm, 50mm, and 60mm mounting diameters, the switches’ construction materials include plastic and stainless steel, aluminum, or polycarbonate. Corresponding 22mm LED signal indicator lights are also IP69K rated and have a 20mm diameter illuminated area; green, red, yellow, white, orange, and magenta signal colors are available.
Available switch types include: static, with the output signal continuously on, as long as the sensor area is activated; dynamic, with the output signal length limited to settable milliseconds, when the sensor area is activated; and toggle, with the output signal turning on when the sensor area is activated and remaining on until the sensor area is activated again.
