Autonics SR1-1440R-N Single-Phase Solid State Relays (Detachable Heatsink Type)
As a member of the SR1 single-phase solid state relay series, the SR1-1440R-N from Autonics uses a detachable heatsink structure for adaptable thermal design in control cabinets. The relay performs contactless switching, which avoids contact wear, arcing, and switching noise while enabling rapid, repeatable cycling. Typical uses include heater control in plastics machinery, food processing lines, and other industrial systems requiring durable single-phase load switching.
