Omron D4C-3302 Limit Switch
Omron D4C-3302 is a general-purpose limit switch with a stainless steel roller plunger for position detection on automated machinery. The roller actuator supports smooth contact with moving cams, slides, and workpieces, while the SPDT contact form provides changeover switching for general control loads. A 5 m four-core VCTF oil-resistant cable supports installations where the sensing point is positioned away from the control wiring, and IP67 protection suits demanding factory environments. The D4C-3302 belongs to the D4C Series within the prewired roller plunger limit switch range from Omron machine control products for reliable travel and end-position detection.

The Omron D4C-3302 Limit Switch uses a 12 mm × 4.4 mm roller plunger with a sintered stainless steel roller for position detection on automated machinery. The roller actuator provides smooth contact with moving cams, slides, conveyors, and workpieces, making it suitable for repeated machine travel and end-position sensing. Its SPDT contact form supports changeover switching for general control loads, with a 4 A at 30 VDC rating. A 5 m four-core VCTF oil-resistant cable is supplied for flexible wiring across machine layouts, with a nominal conductor area of 0.75 mm² and a cable diameter of 7.6 mm. IP67 protection supports demanding factory use.
The D4C-3302 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 and malfunction shock resistance reaches 500 m/s² maximum. These characteristics make the model useful where a roller-plunger limit switch must combine sealed industrial protection with a longer prewired cable for installation flexibility. The 5 m oil-resistant cable is a key difference when routing through larger machinery or oily environments. For a related D4C roller-plunger version without the same cable emphasis, see the D4C-3202 model.
