Omron D4C-1632 Limit Switch
Omron D4C-1632 is a general-purpose limit switch with a sealed roller plunger using a 12 mm dia. × 4.4 mm sintered stainless-steel roller. It has an SPDT contact form and ratings of 5 A at 250 VAC and 4 A at 30 VDC for general load. IP67 protection and Class I construction with an earth wire are specified. The D4C-1632 Sealed Roller Plunger belongs to the D4C Series within the Omron Sealed Limit Switch Range from Omron Switching Components. Its sealed roller-plunger construction, stainless-steel roller, SPDT contacts, and AC/DC ratings provide the core model specifications.

The Omron D4C-1632 Limit Switch is a general-purpose model with a sealed roller plunger using a 12 mm dia. × 4.4 mm sintered stainless-steel roller. It has SPDT contacts and general-load ratings of 5 A at 250 VAC and 4 A at 30 VDC. Frequency is 50/60 Hz, while maximum inrush current is 20 A for NC and 10 A for NO. The operating temperature range is -10 to 70°C with no icing, relative humidity is 35 to 95%, and pollution degree 3 is specified according to EN60947-5-1.
Destructive shock resistance is 1,000 m/s² maximum and malfunction shock resistance is 500 m/s² maximum. Class I construction with an earth wire and IP67 protection are listed. The sealed roller plunger is the primary mechanical identifier, followed by the 12 × 4.4 mm sintered stainless-steel roller, SPDT contact form, general-load classification, and AC/DC ratings. The source row does not provide a separate cable specification, contact resistance, insulation resistance, or durability figure, so none is imported from other D4C models. This keeps the D4C-1632 page focused on its documented sealed-plunger configuration. No separate operation mechanism or pretravel value is identified in the supplied structured row. For another sealed-plunger D4C model that uses a 10 mm stainless-steel pin plunger instead of a roller, see D4C-1231.
