Omron D4C-1631 Limit Switch
Omron D4C-1631 is a general-purpose limit switch with a sealed 10 mm stainless steel pin plunger for direct machine position and end-of-travel detection. The straight plunger actuator is suited to moving parts that approach the switch head-on, while the SPDT contact form supports changeover switching for general loads. Electrical ratings of 5 A at 250 VAC and 4 A at 30 VDC cover common industrial control circuits, and IP67 protection supports dusty or wet environments. The D4C-1631 belongs to the D4C Series within the sealed industrial position switch range from Omron automation components for reliable machine movement detection.

The Omron D4C-1631 Limit Switch uses a sealed 10 mm stainless steel pin plunger for direct mechanical position detection in general-purpose industrial machines. The plunger-style actuator suits applications where a moving part approaches the switch in a straight line and requires a compact contact point. Its SPDT contact form provides changeover switching for control circuits. Electrical ratings include 5 A at 250 VAC and 4 A at 30 VDC for general loads, with inrush current up to 20 A on the NC side and 10 A on the NO side. IP67 protection helps the sealed switch operate around dust, water, and factory contaminants.
D4C-1631 operates from -10 to 70°C with 35 to 95% relative humidity and is specified for pollution degree 3 under EN 60947-5-1. Shock resistance reaches 1,000 m/s² maximum for destruction and 500 m/s² maximum for malfunction. The switch is classified as Class I with an earth wire, supporting protective grounding in the installation. These characteristics make the model suitable for machine position, end-of-travel, and presence detection where a sealed stainless steel plunger and standard SPDT switching are required. For another D4C model using a sealed roller plunger and a prewired 5 m cable, see the D4C-2332.
