Altech’s line of safety relays are manufactured by
, a company well know in Europe for its quality safety relays. The products presented in this catalog will help you meet requirements
of Machinery Directive 2006/42/EC, important international safety standards, CE-marking demand, and more, when exporting your machinery or equipment.
What is a Safety Relay?
A safety relay contains force guided contacts; they are also known as captive, locked or positive guided contacts. Force guidance in a relay means that the contacts in a contact set must be
mechanically linked together so that it is impossible for the NO (normally open) and NC (normally closed) contacts to be closed at the same time. The contacts are linked so that no one contact
in a relay can change state without changing all the contacts in that relay. There must be a 0.5 mm minimum air gap between the open contacts for the entire service life of the relay, even in
the case of a failure. The force guidance of the relay contacts must always be preserved even when a relay part fails to function correctly.
Our technical experts welcome the opportunity to answer your technical questions and provide solutions to your automation and control problems. Give us a call or visit www.altechcorp.com.
