Inductive proximity switches grow with their tasks

When we receive inquiries about devices for the reliable detection of metallic objects, we usually recommend inductive sensors. And for good reason, as there is no more reliable and robust solution for a specific application than this tried and tested technology.

In order to be able to use inductive sensors even at high ambient temperatures, ipf electronic offers a whole range of devices whose maximum permissible ambient temperature far exceeds the usual +80°C. Exposure to heat on electronic components, especially semiconductor technology, generally has negative effects: The life of the devices decreases, leading to rapid total failure if the permissible ambient temperatures are significantly overrun. But even slight overruns can lead to increasing internal resistance, which is commonly known as "temperature drift".

Nevertheless, ipf electronic can offer inductive sensors that can be used at ambient temperatures of up to +140°C (M8 design) and +150°C (M12 design) without having to separate the sensitive electronics from the self-test sensor. Solutions in larger designs even work extremely reliably up to +180°C. And for applications where temperature resistance of up to +230°C is required, the devices are available in the M18, M30, M50 and 40x40 designs. In these two-part systems, the temperature-sensitive electronics are located in a separate amplifier.

A particular advantage for the practical application of these devices: the cable lengths can be selected individually, whereby the user can shorten the pre-wired lines as required. This allows line lengths of up to 25 meters to be achieved.
