Just twelve millimeters in length and three millimeters in diameter – these tiny dimensions make the MiniMini the smallest inductive sensor in the world.
The enormous reduction in size was made possible by using the latest mixed-signal ASIC technology. This technique combines analog signal processing with digital computing power on a single chip, making it particularly suitable for all applications where signals are recorded in analog form, but must be digitized for transmission. Another advantage is that, by eliminating the need to use analog components, device reliability is increased.
“We are proud that, in our 40th anniversary year, we are once again demonstrating our ability to innovate”, says Annette Heimlicher, CEO of Contrinex AG.
The MiniMini impresses with its high switching frequency of 8 kHz and excellent temperature stability from -25 ° C to +70 ° C. Alongside the standard version with a plastic cap Contrinex also offers a version with a ceramic sensing face. This type is pressure resistant up to 200 bar and has IP68/IP69K protection. With a plastic cap the switching distance is 1 mm; with a ceramic cover it is 0.8 mm.
