SCHRACK FORCE GUIDED RELAYS For safety solutions SCHRACK Force Guided Relays are used in safety circuits in combination with light curtains, interlock switches, and emergency stop switches to control outputs. In the design of the Force Guided Relays, special importance was attached to the switching of low loads by the monitoring circuit. TE Connectivity (TE) has developed comprehensive documentation of Forced Guided Relays which supports accelerating the development process for safety controls and application notes help to point out possible error sources. CREDIBILITY & RELIABILITY INDUSTRY 4.0 • Established in the relay market for 20 years • High volume manufacturing • Innovators in replacing contactors in safety circuits • Virtually fully automated packing improves traceability INDUSTRY STANDARDS EASE DESIGN-IN PROCESS & SUPPORT & CERTIFICATIONS • TE has developed special procedures to provide contact reliability • Comprehensive documentation accelerates the development process for safety controls • CCC, UL, TUV & VDE* • Sealed against external influences according to IEC • IEC 61810-3 protection category RTIII *for exact product approvals please refer to the individual product group data sheet INDUSTRIAL / SCHRACK FORCE GUIDED RELAYS 2 TE has extensive capabilities in the design and manufacturing of relays and a broad portfolio of switching solutions for demanding, high performance applications. These relay products are remotely actuated to control electrical power flow by either interrupting or completing an electrical circuit. In many safety critical applications only a special version of an electro mechanical relay can be used, a Force Guided Relays, according to IEC 61810-3. The special design connects NC (normally closed) and NO (normally open) contacts through an actuator, so that one contact interacts with all the other contacts during switching operation in a planned, forced manner. The ultimate goal is, in case of contact welding or other potential failure modes of the relay, to enable a minimum of 0.5 mm (0.20 inch) contact gap of the antivalent contacts – in other words, NO and NC contacts can never be closed at the same time throughout the whole life cycle of the relay and allow operations to switch into a safe state. TE’s SCHRACK Force Guided Relays are essential for safety control applications and help protect people’s lives & health when danger needs to be addressed in applications. FOCUS APPLICATIONS: • Machine safety such as presses, cutting machines and robot controls • Building automation such as elevator, escalator and door controls • Railway such as signaling, break controls, level crossings controls • Medical devices such as x-ray, ventilation and diagnostic systems Safety is paramount for human beings in all areas of our daily lives.
