Omron D4C-3402 Limit Switch
Omron D4C-3402 features a 12 mm × 4.4 mm sintered stainless steel roller plunger, SPDT contacts, and a 4 A at 30 VDC rating. A four-core 3 m VCTF cable is already connected to the switch, while IP67 protection and a specified operating range of -10 to 70°C form part of its enclosure and operating specifications. Mechanical durability is listed at 10 million operations. The D4C-3402 belongs to the D4C Series within the roller plunger limit switch range from Omron switching products, with its 3 m cable and standard roller plunger distinguishing it from cross-roller and lever versions.

The Omron D4C-3402 Limit Switch uses a conventional roller plunger instead of the cross-roller or lever arrangements found on several nearby D4C models. The actuator consists of a 12 mm × 4.4 mm sintered stainless steel roller and works with an SPDT contact configuration rated at 4 A at 30 VDC. The switch is supplied with a four-core 3 m VCTF cable having a nominal conductor section of 0.75 mm² and a diameter of 7.6 mm. IP67 protection is specified, together with an operating temperature of -10 to 70°C and 35 to 95% relative humidity.
Mechanical life is listed at 10 million operations minimum, and maximum contact resistance is 300 mΩ. The shock specification is 1,000 m/s² maximum for destruction and 500 m/s² maximum for malfunction. Unlike the D4C-3203, which changes roller orientation for directional actuation, this model retains a standard roller-plunger configuration. That actuator difference is one of the clearest ways to select between these two otherwise similar 30 VDC, 3 m cable versions. For a direct comparison with the cross-roller configuration, see the D4C-3203 model.
