It gives you one normally-closed and one normally-open contact set in a single housing, rated to switch 5 A on both AC and DC circuits. The sealed roller plunger means the actuator is a spring-loaded pin with a small roller on top, enclosed in a way that keeps contaminants out. With an IP67 rating, the switch body and actuator seal against dust ingress and temporary immersion — it handles washdown environments and wet plant floors without failing. The 5 A switching current at 250 V AC covers most control-circuit loads — contactors, relays, solenoid valves — but it is not a power-switching device. The DC side is rated at 5 A at only 14 V, which is a hard constraint: if your circuit runs 24 VDC at any significant current, the contacts will arc and fail. That 14 V DC rating is the maximum voltage at the full 5 A; for higher DC voltages you must derate the current, and the datasheet curve governs that. The 11.77 N operating force is firm enough to resist false trips from vibration but light enough that a cam or machine slide can actuate it without stalling. Screw terminals simplify field wiring — no special crimp tool needed, just strip and torque. Because the D4E Series is a mature line, the supply is stable but not ramping.","metaTitle":"D4E1D20N Limit Switch, Sealed Roller Plunger, 1NC+1NO, IP67","metaDescription":"D4E1D20N limit switch from the D4E Series.
