Omron D4C-1203 Limit Switch
Omron D4C-1203 is a general-purpose limit switch with a stainless steel cross roller plunger for directional machine position detection. The cross-roller actuator suits cams, slides, and workpieces that approach 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 machine control circuits, and IP67 protection suits demanding factory environments. The D4C-1203 belongs to the D4C Series within the cross roller plunger limit switch range from Omron automation components for reliable machine position and travel detection.

The Omron D4C-1203 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 is suited to cams, slides, and workpieces that move across the actuator from the side, providing smooth rolling contact during repeated operation. Its SPDT contact form provides changeover switching for general loads, with ratings of 5 A at 250 VAC and 4 A at 30 VDC. Inrush current capability reaches 20 A maximum on the NC side and 10 A maximum on the NO side. IP67 protection supports use around dust, water, and factory contaminants.
D4C-1203 operates from -10 to 70°C with 35 to 95% relative humidity and is specified for pollution degree 3 under EN60947-5-1. It is a Class I device with an earth wire for grounded machine installations. Destructive shock resistance reaches 1,000 m/s² maximum, while malfunction shock resistance reaches 500 m/s² maximum. These characteristics make the model suitable for repeatable cross-direction position sensing where a roller actuator, SPDT switching, and sealed industrial protection are required. The 50/60 Hz rating also supports standard AC control applications. For a related D4C model using a sealed roller plunger for similar machine-position duties, see the D4C-1332 model.
