Omron D4C-1601 Limit Switch
Omron D4C-1601 is a general-purpose limit switch with a 10 mm stainless steel pin plunger for direct machine position detection. The straight actuator suits stops, slides, and moving parts that approach the switch head-on, 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 IP67 protection for the enclosed switch body. The D4C-1601 belongs to the D4C Series within the pin plunger limit switch range from Omron control products for direct travel and end-position sensing where straight plunger contact and SPDT switching are required.

The Omron D4C-1601 Limit Switch uses a 10 mm stainless steel pin plunger for direct mechanical position detection. The straight actuator suits stops, slides, and moving parts that approach the sensing point head-on, while the SPDT contact form provides changeover switching for general loads. Electrical ratings are 5 A at 250 VAC and 4 A at 30 VDC, with inrush capability of 20 A maximum on the NC side and 10 A maximum on the NO side. IP67 protection covers the enclosed switch body. The model operates from -10 to 70°C with 35 to 95% relative humidity.
The D4C-1601 is specified for up to 120 mechanical operations and 30 electrical operations per minute. It 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, while malfunction shock resistance reaches 500 m/s² maximum. These characteristics suit direct end-position sensing where the moving target presses axially into a stainless steel plunger. The pin plunger is the main mechanical distinction when comparing this version with cross-roller models in the same D4C group. For a related D4C model using a cross roller plunger with the same electrical ratings and operating-frequency values, see the D4C-1603 model.
