THICKNESS
0.030” (0.762 mm) to 0.5” (12.7 mm) Less Than 0.125” (3.175 mm) 0.5” (12.7 mm) with bushing or panel mount options Less Than 0.25” (6.35 mm) 0.030” (0.762 mm)
MATERIALS Aluminum, stainless-steel, ceramics, stone, granite, glass and some plastics Metal (only when isolated), plastics and glass Any No metals, only non-conductive plastics and glass Aluminum, stainless-steel, and plastics
INTERFACE Finger, glove, rubber, overlays Conductive materials only Any Conductive materials only Any
SUSCEPTIBILITY INTERFERENCE None EMI, ESD susceptible None RFI, EMI and ESD susceptible ESD susceptible
LINEAR
DENSITY
6 per Inch 2 per inch (must be isolated) Limited by physical construction 2 per inch (limited by size of sensor) 1–2 per inch (must be isolated)
INTELLIGENCE Yes, Self-adapting, Self-diagnosing, Error reporting, Communications (RS232, USB, CAN Bus, etc.) None, cannot distinguish between accidental and intentional actuations None None, cannot distinguish between accidental and intentional actuations None
SEALING Completely sealed, Not effected by water pressure Partially sealed, Moisture causes false actuations Available Partially sealed, Moisture can interfere with sensor peration Sealed, but can not be submerged and may falsely actuate under pressure
DESIGN
LIMITATIONS
Limited only by your imagination Capacitive sensors cannot be integrated into existing enclosures Capacitive sensors cannot be sterilized or exposed to moisture, explosive, and corrosive conditions Electro-mechanical switches require panel cut-outs and can not be located on curved surfaces EMF has limited ability to be used in harsh environments Piezo-electric sensors are suited for use only on extremely thin metal surfaces and never with elastomeric overlays As a high volume manufacturing matter, piezo is the most expensive
