So often it is the small elements that make the critical difference for design and usability. Without a doubt this includes ball catches and magnetic catches that – although unseen – can significantly optimize a machine, fixture or installation in qualitative terms.
Ball catches of the series GN 4490 offer a very elegant and space-saving way to meet these requirements. The mounting block attached to the moving element engages in the ball catch precisely between the two spring-loaded balls for a positive and non-positive connection. Depending on the size and version, retaining force is between 25 and 150 Newtons. Both parts can be variably positioned, oriented either horizontally or vertically and with engagement from the front or the side.
If the installation situation does not permit the desired positioning, such as for mounting on aluminum profiles, this problem can be easily solved with mounting plates for ball housings GN 4490.1 or with mounting plates for mounting blocks GN 4490.2.
As an alternative to mechanical closure, Ganter’s magnetic catches GN 4470 represent another option. They are a compact solution for use in practically all situations and are simpler to install than ball catches while offering the same tolerances. The strongest neodymium magnets are enclosed in a powder-coated zinc die cast housing, which is covered by a layer of rubber to reduce closing noises and prevent metal-on-metal contact. The magnetic elements are mounted using a slot or through hole. The magnet can be oriented upwards or to the side and combined with the matching stop plates to adapt to almost any installation situation. The zinc-plated stop plates are also useful when the cover or door is made of non-magnetic materials. GN 4470 can also be used with sliding doors.
