High temperature (HT) inductive proximity switches.
For demanding applications in high temperature areas, inductive proximity switches with good long-term reliability have become increasingly popular. Contrinex offers a series of embeddable and non-embeddable high temperature switches in sizes M8 to M50. The devices have operating distances from 2 to 25mm, and are respectively suitable for applications up to 140oC, 150oC, 180oC and 230oC.
The executions for 140oC, 150oC and180oC feature built-in amplifiers. Connection by means of a 2m silicone or Teflon cable is standard. Other cable lengths and types are available on request.
For 230oC types, the amplifiers are built into an M12 stainless steel housing, which is connected by means of a standard 3m Teflon cable, and thus removed from the hot area. This cable carries a pure DC, rather than a high-frequency signal, and its length can thus be chosen freely, without having a negative influence on the switching behaviour of the device and without the need for adjustment. Connection of the amplifier is by means of a 2m PUR cable.
All the usual protection functions, such as short-circuit, overload and voltage-reversal protection are built in. Furthermore, the devices feature good protection against environmental influences (IP67).
