Omron D4C-1503 Limit Switch is a general-purpose limit switch with a cross roller plunger using a 12 mm × 4.4 mm sintered stainless-steel roller. The contact form is SPDT and the model is listed for general load. Electrical values include 5 A at 250 VAC and 4 A at 30 VDC, with NC current specified as 20 A max. and NO current as 10 A max. Frequency is 50/60 Hz. These values identify the D4C-1503 through actuator form, roller dimensions and material, SPDT contact configuration, load classification, current values, and operating frequency. The actuator is listed as a cross roller plunger without the sealed wording used for the D4C-1433 row.
The D4C-1503 carries IP67 protection, pollution degree 3 according to EN60947-5-1, and Class I classification with earth wire. Its operating temperature range is -10 to 70°C with no icing, while humidity is 35 to 95% RH. Shock specifications are 1,000 m/s² max. for destruction and 500 m/s² max. for malfunction. In the same uploaded batch, the D4C-1433 shares the same cross-roller dimensions, sintered stainless-steel roller, SPDT contacts, load values, frequency, and environmental specifications, while its actuator is explicitly described as sealed. See the D4C-1433.
