Omron D4C-1231 Limit Switch
Omron D4C-1231 is a general-purpose limit switch with a sealed pin plunger made from a 10 mm diameter stainless-steel plunger. It uses an SPDT contact form and is rated at 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-1231 Sealed Pin Plunger Switch is part of the D4C Series in the Omron Plunger Limit Switch Collection from Omron Product Range. Frequency is 50/60 Hz, with maximum inrush current of 20 A for NC and 10 A for NO.

The Omron D4C-1231 Limit Switch uses a sealed pin plunger with a 10 mm diameter stainless-steel plunger. It is classified as a general-purpose limit switch with 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 core model identity is the sealed 10 mm stainless-steel pin plunger together with SPDT switching and the 5 A at 250 VAC / 4 A at 30 VDC general-load ratings. The structured row does not provide a cable type, cable length, contact resistance, insulation resistance, or durability value, so those details are not added from legacy text. No operation mechanism is separately specified, and no actuator material beyond stainless steel is added. For another sealed-plunger D4C model that uses a 12 × 4.4 mm roller rather than a pin plunger, see D4C-1632.
