Omron D4C-1303 Limit Switch
Omron D4C-1303 is a general-purpose limit switch with a 12 mm × 4.4 mm cross roller plunger using a sintered stainless steel roller for directional machine position detection. The cross-roller actuator suits moving parts that pass across the sensing point from a defined direction, while the SPDT contact form provides changeover switching for general loads. Electrical ratings of 5 A at 250 VAC and 4 A at 30 VDC support common control circuits, with high inrush capability on the NC and NO sides. IP67 protection supports enclosed installations. The D4C-1303 belongs to the D4C Series within the cross roller plunger switch range from Omron control components for directional travel and position sensing.

The Omron D4C-1303 Limit Switch uses a 12 mm × 4.4 mm cross roller plunger with a sintered stainless steel roller for directional machine position detection. The cross-roller arrangement suits moving parts that pass across the sensing point from a defined direction, while the SPDT contact form provides changeover switching for general loads. Electrical ratings are 5 A at 250 VAC and 4 A at 30 VDC, with inrush current capability of 20 A maximum on the NC side and 10 A maximum on the NO side. IP67 protection supports enclosed installations where the switch is repeatedly actuated by moving machine components.
Mechanical durability is specified at 10 million operations minimum, while electrical durability reaches 200,000 operations minimum at 5 A, 125 VAC. Initial contact resistance is 400 mΩ maximum. The D4C-1303 operates from -10 to 70°C with 35 to 95% relative humidity. Destructive shock resistance reaches 1,000 m/s² maximum, while malfunction shock resistance reaches 500 m/s² maximum. These characteristics suit directional roller-plunger sensing where the target passes across the actuator rather than pressing straight into it. The cross-roller geometry is the main distinction compared with a plain pin plunger. For a related D4C model using a direct stainless steel pin plunger, see the D4C-1301 model.
