Omron D4C-1502 Limit Switch
Omron D4C-1502 is a general-purpose limit switch with a stainless steel roller plunger for mechanical position detection on industrial equipment. The rolling actuator suits cams, slides, conveyors, and workpieces that move across the sensing point, helping reduce direct sliding contact during repeated operation. Its SPDT contact form supports changeover switching, with 5 A at 250 VAC and 4 A at 30 VDC ratings for standard control loads. IP67 protection supports harsh factory conditions. The D4C-1502 belongs to the D4C Series within the roller plunger limit switch range from Omron industrial control components for dependable machine travel and end-position detection.

The Omron D4C-1502 Limit Switch uses a 12 mm × 4.4 mm sintered stainless steel roller plunger for mechanical position detection on moving industrial equipment. The roller actuator is suited to cams, slides, conveyors, and workpieces that pass across the sensing point, reducing direct sliding contact compared with a fixed plunger. Its SPDT contact form provides changeover switching for control circuits. Electrical ratings are 5 A at 250 VAC and 4 A at 30 VDC for general loads, with inrush capability up to 20 A on the NC side and 10 A on the NO side. IP67 protection helps the switch operate around dust, water, and common factory contaminants.
The D4C-1502 is specified for at least 10 million mechanical operations and 200,000 electrical operations at 5 A, 125 VAC. Contact resistance is 400 mΩ maximum. The switch operates from -10 to 70°C with 35 to 95% relative humidity and withstands destructive shock up to 1,000 m/s² and malfunction shock up to 500 m/s². These characteristics make it suitable for repeated roller-actuated position sensing where compact construction, sealed protection, and standard SPDT switching are required. The stainless steel roller also supports durable contact with moving machine parts in frequent cycling applications.
