These sensors are dual reed style with an operating life of over 2 million cycles.  Most sensors are of the coded magnet style, which means they are constructed with anti-manipulation reeds that make it difficult to defeat with a standard magnet.  This helps prevent unauthorized entry into a dangerous area.  Many styles feature connector models which make change out in the case of damage, a very simple proposition.  Food grade (FDA approved) sensors and magnets are also available for the food processing industry.  Hygienic magnets are made with no sharp edges where contamination can hide.  These magnets combined with FDA approved sensors can be subjected to wash-down at 250 psi and 100 o C.
