The ring magnet (ELE03416) is part of the locking mechanism in the door leaf of the gas-tight hinged door from HT Group. It has an outer diameter of 15 mm, a height of 4.5 mm, and a 5.5 mm hole with a 90° countersink, allowing it to be mounted flush with an M5 countersunk screw.

The material used is N42 grade neodymium-iron-boron. The magnet is axially magnetized, meaning the poles are located on the two end faces. The nickel-plated surface protects the base material and is easy to clean.

The thrust washer NOR02001 is used as a sliding washer for the magnet. It is fastened using the countersunk screw NOR01834; the tightening torque is 3 to 5 Nm. Due to the high number of operations, the countersunk screw must be secured with a liquid threadlocker. The ring magnet is supplied individually and is a spare part for maintenance and repair.
