Omron D4C-3203 Limit Switch
Omron D4C-3203 combines a 12 mm × 4.4 mm cross roller plunger with SPDT switching for directional mechanical detection. Its sintered stainless steel roller is paired with a 4 A at 30 VDC rating and a 3 m, four-core VCTF oil-resistant cable, giving this version a clearly defined DC and prewired configuration. IP67 protection is also specified for the switch body. The D4C-3203 is part of the D4C Series and fits within the cross roller plunger limit switch range from Omron switching components for applications requiring lateral roller contact and a 3 m cable connection.

The Omron D4C-3203 Limit Switch is configured around a cross roller plunger measuring 12 mm × 4.4 mm and manufactured with a sintered stainless steel roller. This actuator format is the key distinction of the model because the roller orientation is designed for contact across the plunger rather than the straight axial action of a pin plunger. The SPDT contact arrangement is rated at 4 A at 30 VDC. Wiring is already provided through a four-core, 3 m VCTF oil-resistant cable with a nominal conductor section of 0.75 mm² and an overall diameter of 7.6 mm. IP67 protection is specified, together with operation from -10 to 70°C and 35 to 95% RH.
Mechanical durability is listed at 10 million operations minimum, and the supplied data gives 300 mΩ as the maximum contact resistance. Shock resistance is specified at 1,000 m/s² maximum for destruction and 500 m/s² maximum for malfunction. These details make actuator direction, 30 VDC rating, and 3 m oil-resistant cable the most useful points when identifying this particular D4C version. A buyer comparing actuator formats can contrast it with the D4C-3402, which uses a standard roller plunger rather than a cross roller arrangement.
