Electromagnetic bolts have a front strip and a clamp made of stainless steel and a bolt made of chromed steel. Bolts Co 101 and Co 102 are also available in versions without a front profile and a clamp.

The cover of the electromagnetic bolts is made of galvanized steel (Co 101, Co 102, Co 202) or stainless steel (Co 401, Co 402). As standard, electromagnetic bolts are equipped with bolt and door position sensors, but cheaper versions without sensors are also available. Bolts with numbers Co 101, Co 401 are fail-safe (normally open), i.e. they need power to close, unlike bolts with numbers Co 102, Co 202, Co 402 of fail-secure (normally closed), in which power supply is required to open. Bolts are manufactured for 12 or 24 V supply voltage and allow for over two million opening-closing cycles without any maintenance. Depending on the type, electromagnetic bolts are available in surface and recessed versions and are adapted for horizontal or vertical installation. The exact technical data and the method of bolt assembly can be found in the PDF data sheet (located above for download).
