The Omron D4F-102-1R Limit Switch is a roller-lever actuated safety/position-detection switch used in industrial automation to detect the position, presence, or movement of mechanical parts, enabling safety interlocks in machine guards, conveyors, packaging equipment, and automated production lines. The D4F series features a panel-mount design with a terminal-block connection and a die-cast metal housing rated IP67, suitable for harsh environments. It provides a 1NC/1NO contact configuration and tolerates voltages up to 250 VAC and currents up to 5 A, with an operating temperature range of -30°C to 70°C. Common replacements include Omron D4F-102-5R, D4N-112G, and D4B-1110N.
