Omron D4C-1232 Limit Switch
Omron D4C-1232 is a general-purpose limit switch with a sealed 12 mm × 4.4 mm sintered stainless steel roller plunger for repeatable position detection. The rolling actuator suits cams, slides, conveyors, and moving workpieces that pass across the sensing point, while the sealed construction helps protect the mechanism from factory contaminants. Its SPDT contact form supports changeover switching for general loads, with ratings of 5 A at 250 VAC and 4 A at 30 VDC. IP67 protection supports demanding industrial environments. The D4C-1232 belongs to the D4C Series within the sealed roller plunger switch range from Omron automation components for reliable machine travel and end-position sensing.

The Omron D4C-1232 Limit Switch uses a sealed 12 mm × 4.4 mm roller plunger with a sintered stainless steel roller for repeatable machine position detection. The rolling actuator suits cams, slides, conveyors, and moving workpieces that pass across the sensing point, while the sealed construction helps protect the mechanism from factory contaminants. 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 demanding industrial installations.
The D4C-1232 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 support sealed roller-plunger sensing where general-load switching, environmental protection, and durable rolling contact are important. The actuator is especially suited to moving targets that sweep across the sensing point rather than pressing directly into a pin plunger. For a related D4C sealed roller-plunger model with closely matched general-load characteristics, see the D4C-1332 model.
