... Moving Loop System In the U.S.A., the National Association of Relay Manufactures (NARM) in April 1984, awarded OMRON for monumental advances in relay technology, as embodied in the Moving Loop System. This unique relay construction maximizes electrical and permanent magnet energy. A high-efficiency magnet adds to the magnetic flux of the relay coil, which also allows for tighter packing of relay parts. Relays having such a coil are known as “ ...

... A current which serves as a reference in determining the perfor- mance of the relay contacts. This value will never exceed the current flow. When using a relay, do not exceed this value. Contact Form OMRON uses the following relay terminology for the various polarity and switch configurations. 1 FORM A: SPST-NO 1 FORM B: SPST-NC ...

... This value may vary, depending on operating frequency, operating conditions, expected reliability level of the relay, etc always recommended to double-check relay suitability under actual load conditions. In Omron catalogs, the minimum permissible load of each relay is indicated as a reference value. It indicates failure level at a reliability ). λ -6 level of 60% (λ ...

... PCBs having a thickness of 0.8, 1.2, 1.6, or 2.0 mm are generally used. A PCB that is 1.6 mm thick is best for mounting a PCB relay, considering the weight of the relay and the length of the terminals. (The terminal length of OMRON relays is 3, 3.5, or 4.0 to 5.0 mm.) 3.5 ■ Terminal Hole Diameter and ...
