Omron D4C-1420 Limit Switch
Omron D4C-1420 is a general-purpose limit switch with an R38 roller lever and a 17.5 mm dia. × 7 mm sintered stainless-steel roller. It uses SPDT contacts 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-1420 R38 Roller Lever Switch belongs to the D4C Series within the Omron Roller Lever Limit Switch Range from Omron Switch Component Range. Frequency is 50/60 Hz, while maximum inrush current is 20 A for NC and 10 A for NO.

The Omron D4C-1420 Limit Switch is a general-purpose roller-lever model with an R38 lever and a 17.5 mm dia. × 7 mm sintered stainless-steel roller. It uses an SPDT contact form and has general-load ratings of 5 A at 250 VAC and 4 A at 30 VDC. Frequency is 50/60 Hz, and maximum inrush current is specified at 20 A for NC and 10 A for NO. Operating temperature ranges from -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 and IP67 protection are specified. The R38 lever geometry is the main actuator detail, while the 17.5 × 7 mm roller, SPDT contacts, general-load class, and AC/DC ratings complete the model profile. The source does not provide cable length, contact resistance, insulation resistance, or durability values for this row, so those details are omitted rather than taken from another D4C variant. No operation mechanism, pretravel value, or separate actuator direction is identified in the supplied structured row. For an adjustable roller-lever D4C model using the same roller dimensions and load ratings, see D4C-1227-P.
