The Pickering 10-520-012 is a single-pole, single-throw (SPST) normally open (NO) reed relay engineered for high-density switching matrices and multiplexing in automatic test equipment. This ultra-compact component occupies just 4 mm² footprint, delivering 5 W switching power at up to 0.5 A with sputtered ruthenium instrumentation-grade contacts. Internal mu-metal magnetic screening eliminates cross-talk, enabling dense stacking without relay interaction—critical for large-scale ATE switching arrays.
