ABSTRACT:
The polarized, electromagnetic relay includes a magnet frame, relative to conduit rabbets, with angles-off yoke arrangement, which includes two separated, parallel-arranged yokes, as well as a permanent magnet that lies therebetween and between anchor plates. The two yokes are L-shaped and formed exactly identical, whereby their core shanks stretch over the entire length of the exciter coil, and lie next to each other in the region of the exciter coil. Thereby a mechanically and electrically absolutely symmetrical magnet frame results, whose asymmetry is compensated by losses arising from the air gap. Through the use of individual yokes there ensues a simple assembly in the spring jack, which functions as holding element for all of the parts.
