Omron D4C-3227-P Limit Switch is a general-purpose limit switch with an adjustable roller lever using a 17.5 mm × 7 mm sintered stainless-steel roller. Its contact form is SPDT and the model is listed for general load. The source gives 4 A at 30 VDC as an electrical value, with NC current specified as 20 A max. and NO current as 10 A max. Contact resistance is 300 mΩ max. These characteristics identify the D4C-3227-P through adjustable roller-lever actuation, roller size and material, SPDT contacts, general-load classification, electrical value, current limits, and contact resistance. The adjustable roller lever is distinct from the cross-roller plunger configurations appearing elsewhere in the same D4C batch.
The D4C-3227-P is rated IP67 and has pollution degree 3 according to EN60947-5-1. It is also listed as Class I with earth wire. The operating temperature range is -10 to 70°C with no icing and humidity is 35 to 95% RH. Shock specifications are 1,000 m/s² max. for destruction and 500 m/s² max. for malfunction. These values provide the environmental limits supplied for the model without adding unstated installation or application claims. For another D4C model in the same batch using a stainless-steel roller, see the D4C-1433.
