Omron D4C-4233 Limit Switch
Omron D4C-4233 is a compact limit switch with a sealed cross roller plunger for directional machine position detection. Its stainless steel roller suits targets that move across the actuator from the side, while the SPDT contact form supports changeover switching in low-current control circuits. The microload rating makes this model relevant for signal-level applications where precise position feedback is more important than high-load switching. IP67 protection supports use around dust, moisture, and industrial contaminants. The D4C-4233 belongs to the D4C Series within the microload position switch range from Omron machine control products for accurate travel and position detection.

The Omron D4C-4233 Limit Switch uses a sealed cross roller plunger with a 12 mm × 4.4 mm sintered stainless steel roller for directional mechanical position detection. The cross roller arrangement is suited to machine parts that travel across the actuator rather than pressing directly into a pin plunger. Its SPDT contact form provides changeover switching, while the microload rating is 0.1 A at 125 VAC and 0.1 A at 30 VDC. A 3 m, four-core VCTF oil-resistant cable is specified for connection. IP67 protection supports installation where dust, water, oil, or other factory contaminants may reach the switch body.
D4C-4233 operates from -10 to 70°C with 35 to 95% relative humidity. Initial contact resistance is 300 mΩ maximum, while destructive shock resistance reaches 1,000 m/s² and malfunction shock resistance reaches 500 m/s². The sealed actuator and microload switching capability make this model suitable for low-current position signals in automated equipment, particularly where the target moves laterally across the roller. When comparing models, actuator direction, microload rating, cable length, and environmental sealing are the most useful differences to consider. For another sealed D4C configuration using a roller plunger and a longer 5 m oil-resistant cable, see the D4C-2332.
