Omron D4C-1233 Limit Switch
Omron D4C-1233 is a general-purpose limit switch with a sealed roller plunger using a 12 mm × 4.4 mm sintered stainless steel roller for repeatable machine position detection. The sealed roller actuator suits cams, slides, and moving workpieces 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, with high inrush capability on the NC and NO sides. IP67 protection supports enclosed installations. The D4C-1233 belongs to the D4C Series within the sealed roller plunger switch range from Omron automation components for machine position and travel sensing.

The Omron D4C-1233 Limit Switch uses a sealed roller plunger with a 12 mm × 4.4 mm sintered stainless steel roller for repeatable mechanical position detection. The rolling actuator suits cams, slides, and moving parts that pass across the sensing point, while the sealed construction helps protect the operating mechanism. 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 enclosed machine installations.
The D4C-1233 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. Destructive shock resistance reaches 1,000 m/s² maximum, while malfunction shock resistance reaches 500 m/s² maximum. These characteristics suit sealed roller-plunger sensing where general-load switching and rolling contact are required together. The sealed actuator format is especially useful when the target repeatedly passes across the roller and direct sliding contact should be reduced. For a related D4C model using a cross roller plunger for directional target movement, see the D4C-1303 model.
