Omron D4C-1650 Limit Switch
Omron D4C-1650 is a general-purpose limit switch with a flexible resin rod actuator for contact, presence, and machine position detection. The plastic rod can deflect when touched from different directions, making it useful where the target path does not suit a rigid plunger. Its SPDT contact form provides changeover switching for general loads, with ratings of 5 A at 250 VAC and 4 A at 30 VDC. IP67 protection and operation from -10 to 70°C support enclosed machine installations. The D4C-1650 belongs to the D4C Series within the flexible rod limit switch range from Omron control products for contact, travel, and position sensing.

The Omron D4C-1650 Limit Switch uses a flexible resin rod actuator for mechanical contact, presence, and position detection. The rod can deflect when touched from different directions, making it useful where the target does not approach from one exact axis. Its SPDT contact form provides changeover switching for general loads, with ratings of 5 A at 250 VAC and 4 A at 30 VDC. Inrush current capability reaches 20 A maximum on the NC side and 10 A maximum on the NO side. IP67 protection covers the enclosed switch body, and operation is specified from -10 to 70°C with 35 to 95% relative humidity.
The D4C-1650 is listed for pollution degree 3 under EN60947-5-1 and as Class I with an earth wire. Destructive shock resistance reaches 1,000 m/s² maximum. The resin rod is the main actuator feature and should be selected when flexible target contact is more useful than a rigid pin, roller plunger, or lever. Its ability to deflect makes it suitable for presence or travel sensing where the moving component may brush against the actuator. The source does not provide durability, contact-resistance, or vibration values for this row, so those specifications are not added. For a related D4C model using an R38 roller lever instead of a flexible rod, see the D4C-1720 model.
