Omron D4C-4202 Limit Switch
Omron D4C-4202 is a microload roller plunger limit switch with a 12 mm dia. × 4.4 mm sintered stainless-steel roller and SPDT contacts. Its listed ratings are 0.1 A at 125 VAC and 0.1 A at 30 VDC. The model includes a 3 m VCTF oil-resistant four-core cable and carries IP67 protection. The D4C-4202 belongs to the D4C Series within the microload roller plunger switch range from Omron. Its microload rating, SPDT contacts, stainless-steel roller plunger, 3 m cable, and IP67 specification distinguish it from general-load D4C roller-plunger versions with similar actuator dimensions and a different electrical classification.

The Omron D4C-4202 Limit Switch has a maximum contact resistance of 300 mΩ. Electrical durability is 200,000 operations minimum under the listed 5 A at 125 VAC test condition, while mechanical durability is ten million operations minimum. The VCTF oil-resistant cable has four cores, a 3 m length, a nominal sectional area of 0.75 mm², and a 7.6 mm diameter. These details complement the model's 0.1 A at 125 VAC and 0.1 A at 30 VDC microload ratings, SPDT contact form, stainless-steel roller plunger, and IP67 protection.
Operating temperature ranges from -10 to 70°C with no icing, and relative humidity is 35 to 95%. Destructive shock resistance is 1,000 m/s² maximum, while malfunction shock resistance is 500 m/s² maximum. The D4C-4202 is most clearly separated from nearby D4C variants by its microload classification, 12 mm dia. × 4.4 mm roller plunger, 3 m oil-resistant cable, and 300 mΩ contact resistance. Its durability test condition should be read separately from the listed microload ratings. Within the D4C Series, the combination of microload ratings, roller-plunger geometry, SPDT contacts, and the 3 m cable creates a distinct product profile from general-load models with similar mechanical dimensions. For the corresponding general-load roller-plunger version, see D4C-2202.
