Omron D4C-1229-P Limit Switch
Omron D4C-1229-P is a general-purpose limit switch with a 3 mm × 160 mm adjustable stainless steel rod lever for flexible machine position detection. The long rod actuator allows the sensing point to be adjusted to suit different target paths and mounting distances, while the SPDT contact form provides changeover switching for general loads. Electrical ratings of 5 A at 250 VAC and 4 A at 30 VDC support common control circuits, with high inrush capability. IP67 protection supports enclosed installations, and operation from -10 to 70°C covers varied machine conditions. The D4C-1229-P belongs to the D4C Series within the adjustable rod lever switch range from Omron control components for position and travel sensing.

The Omron D4C-1229-P Limit Switch uses a 3 mm × 160 mm adjustable stainless steel rod lever for flexible machine position detection. The long rod allows the sensing point to be adjusted to suit different target paths and mounting distances, making it useful where a short fixed actuator cannot comfortably reach the moving part. Its SPDT contact form supports 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 supports enclosed installations.
The D4C-1229-P operates from -10 to 70°C with 35 to 95% relative humidity and is specified for pollution degree 3 under EN60947-5-1. It is a Class I device with an earth wire. Destructive shock resistance reaches 1,000 m/s² maximum, while malfunction shock resistance reaches 500 m/s² maximum. These characteristics suit position sensing where actuator reach and adjustment are more important than direct plunger contact. The 160 mm stainless steel rod gives the installer more freedom to match the actuator to the target path without relocating the switch body. For a related D4C model using an R38 stainless steel roller lever instead of an adjustable rod, see the D4C-1220-P model.
