Omron D4C-3002-DK1EJ03 Limit Switch
Omron D4C-3002-DK1EJ03 is a D4C Series limit switch with a 12 mm × 4.4 mm sintered stainless steel roller plunger and SPDT contact configuration for DC position sensing. The rolling actuator suits moving parts that pass across the sensing point, while the 1 A at 30 VDC rating supports low-voltage control circuits. A 0.3 m three-core oil-resistant cable provides a short prewired connection, and IP67 protection covers the enclosed switch body. The D4C-3002-DK1EJ03 belongs to the D4C Series within the DC roller plunger limit switch range from Omron control products for compact machine position sensing where short cable routing and DC switching are required.

The Omron D4C-3002-DK1EJ03 Limit Switch uses a 12 mm × 4.4 mm sintered stainless steel roller plunger with an SPDT contact configuration for DC machine position detection. The rolling actuator suits moving parts that pass across the sensing point, while the electrical rating is specified at 1 A at 30 VDC. A three-core 0.3 m oil-resistant cable provides a compact prewired connection. IP67 protection covers the enclosed switch body, and operation is specified from -10 to 70°C with 35 to 95% relative humidity. Destructive shock resistance reaches 1,000 m/s² maximum and malfunction shock resistance reaches 500 m/s² maximum.
Mechanical durability is specified at 10 million operations minimum, while electrical durability reaches 1 million operations minimum at 0.1 A, 30 VDC. Insulation resistance is 100 MΩ minimum at 500 VDC. The short 0.3 m cable is an important selection point where the switch connects close to another connector, junction, or wiring point. The roller plunger provides rolling mechanical contact for targets moving across the actuator. These characteristics distinguish this DC configuration from higher-voltage D4C versions in the same series.
