Omron D4C-1332 Limit Switch
Omron D4C-1332 is a general-purpose limit switch with a sealed stainless steel roller plunger for repeated machine position detection. The rolling actuator suits cams, slides, conveyors, and workpieces that move across the sensing point, while the sealed construction helps protect the mechanism from industrial contaminants. Its SPDT contact form supports standard changeover control, with 5 A at 250 VAC and 4 A at 30 VDC ratings. IP67 protection supports harsh factory conditions. The D4C-1332 belongs to the D4C Series within the sealed roller plunger switch range from Omron industrial control products for dependable travel and end-position sensing.

The Omron D4C-1332 Limit Switch uses a sealed 12 mm × 4.4 mm roller plunger with a sintered stainless steel roller for repeatable position detection in industrial machinery. The sealed roller actuator suits cams, slides, conveyors, and moving workpieces that pass across the sensing point, helping reduce sliding contact while protecting 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 factory installations.
The D4C-1332 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. Contact resistance is 400 mΩ maximum. Destructive shock resistance reaches 1,000 m/s² maximum, with malfunction shock resistance of 500 m/s² maximum. These specifications support frequent roller-plunger actuation in automated equipment where sealed construction, standard SPDT switching, and long service life are important. The model is particularly useful for repeated travel and end-position detection on moving machine components. For another sealed D4C roller-plunger configuration with a 4 A at 30 VDC general-load rating, see the D4C-3332 model.
