In all automated and mining processes inductive sensors are absolutely necessary to provide the PLC with information. The sensors supply the necessary signals on positions, limit or serve as pulse pick-ups for counting tasks or for monitoring rotational speed.
Compared to mechanical switches, inductive sensors offer ideal conditions such as non-contact operation free from any wear and tear; high switching frequencies; and accuracy. In addition, they are insensitive to vibration, dust and moisture. Inductive sensors detect all metals without contact.
The efector m inductive sensors from ifm electronic feature an increased 4-22 mm sensing range. The sensors are suitable for almost all application areas and are resistant to aggressive oils and coolants. They are weld field immune, use the same sensing range for all metals, and offer ferrous only detection. Due to their universal connection technology, the sensors can be used as 2-wire or 3-wire units. The integrated LED provides quick and fast adjustment, reduces mounting time and ensures utilisation of the increased sensing range. All units have a permanent laser etched type label. This allows clear identification of the units even after many years of use.
The sensors have threaded cylindrical brass housings with diameters ranging from M8 to M30 and they offer a choice of NO/NC PNP/NPN outputs.
