Magnetic safety switches are used on perimeter guarding doors and slide or swing-open shields for drills, mills and other machines. These reed-type magnetic safety switches utilize magnetic actuation. They offer non-contact reliability along with tolerance for misalignment.
What is the purpose of a magnetic switch?
Simple magnetic switches are used to detect the opening of doors and windows. A basic magnetic switch comprises two parts— the magnet and a magnetically sensitive switch (usually a reed switch enclosed within a glass envelope). Switches may be either normally open (close on alarm) or normally closed (open on alarm).
What is a safety switch used for?
A safety switch is a device that quickly switches off the electricity supply if an electrical fault is detected, to minimise the risk of electricity-related fires, electric shock, injury and death.
What is magnetic switch sensor?
Magnetic proximity sensors are used for non-contact position detection beyond the normal limits of inductive sensors. ... Since magnetic fields penetrate all non-magnetisable materials, these sensors can detect magnets through walls made of non-ferrous metal, stainless steel, aluminum, plastic or wood.Feb 5, 2018
What is a coded magnet?
Magnets are magnetised using a new method that allows small segments of the magnet to be magnetised individually (aka coded). ... The coding of the segments allows complex magnetic fields to be created, which result in novel magnetic behaviours not seen with conventionally magnetised magnets.
