Omron D4C-1201 Limit Switch
Omron D4C-1201 is a general-purpose limit switch with a 10 mm diameter stainless-steel pin plunger and SPDT contact form. It is rated at 5 A at 250 VAC and 4 A at 30 VDC for general load. Maximum inrush current is 20 A for NC and 10 A for NO, while IP67 protection is specified. The D4C-1201 Stainless Pin Plunger Switch belongs to the D4C Series within the Omron Pin Plunger Limit Switch Range from Omron Industrial Switch Range. Frequency is 50/60 Hz, with Class I construction using an earth wire. Its pin plunger, SPDT contacts, and AC/DC ratings define the model.

The Omron D4C-1201 Limit Switch is a general-purpose D4C Series model with a 10 mm diameter stainless-steel pin plunger and SPDT contact form. It is rated at 5 A at 250 VAC and 4 A at 30 VDC for general load. Frequency is 50/60 Hz, while maximum inrush current is 20 A for NC and 10 A for NO. IP67 protection is specified. The operating temperature range is -10 to 70°C with no icing, relative humidity is 35 to 95%, and pollution degree 3 is listed 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 is also specified. The strongest exact-model terms are D4C Series, general-purpose limit switch, 10 mm stainless-steel pin plunger, SPDT contacts, 5 A at 250 VAC, 4 A at 30 VDC, and IP67 protection. The structured row does not provide a cable type, cable length, contact resistance, insulation resistance, durability figure, operating speed, or operation mechanism. Those details are therefore not taken from the older meta description or other D4C variants. The product page can remain technically distinct through its pin-plunger actuator and stated general-load electrical values without adding unsupported cable claims.
