Omron D4C-1403 Limit Switch
Omron D4C-1403 is a general-purpose limit switch with a 12 mm × 4.4 mm cross roller plunger using a sintered stainless steel roller for directional position detection. The cross-roller actuator suits moving parts that pass across the sensing point, 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, and IP67 protection covers the enclosed switch body. The D4C-1403 belongs to the D4C Series within the cross roller plunger switch range from Omron control products for directional travel, position, and end-point sensing with rolling mechanical contact.

The Omron D4C-1403 Limit Switch uses a 12 mm × 4.4 mm cross roller plunger with a sintered stainless steel roller for directional mechanical position detection. The cross-roller arrangement suits moving parts that pass across the sensing point, 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 capability of 20 A maximum on the NC side and 10 A maximum on the NO side. IP67 protection covers the enclosed switch body. The model operates from -10 to 70°C with 35 to 95% relative humidity.
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 300 mΩ maximum. Destructive shock resistance reaches 1,000 m/s² maximum and malfunction shock resistance reaches 500 m/s² maximum. These specifications suit applications where the target travels across the actuator and rolling contact is preferable to a direct axial push. The cross-roller geometry is the key mechanical distinction and supports directional actuation across the sensing point. For a related D4C model using a straight stainless steel pin plunger instead of a cross roller, see the D4C-1401 model.
