Inductive sensors for the mining industry

October 15th, 2012, Published in Articles: Vector

Inductive sensors are absolutely necessary in all automated and mining processes  to provide the PLC with information. These 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. ifm electronic’s efector m inductive sensors 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 two-wire or three-wire units. The integrated LED provides quick and fast adjustment, reduces mounting time and ensures utilisation of the increased sensing range.
