The FE550 is a VDS approved door holder in a reinforced plastic box. These door holding magnets are the result of years of specialised development. Rated at just 1.5 W @ 24VDC, these powerful magnets pack a holding power of 490 N. All magnets have a spring-loaded pin to ensure ejection against remnant magnetism. The reinforced plastic box model offers a cost effective solution without sacrificing performance. The FE550 is supplied without a keeper plate. This may be ordered separately depending on the application.For practical ease of installation, all units are complete with electrical termination. Protection diodes prevent electromagnetic pulses, and reverse polarity protection speeds up installation. The boxes are predrilled in a practical, standard format for rapid mounting. All models are VdS approved. (Refer to the device specification)
