D4E-1D20N — Interrupteur de fin de course

This item is the D4E-1D20N roller-plunger small sealed limit switch, an exact-match part number used for industrial position detection and end-stop sensing. It features an SPDT (1NO/1NC) snap-action contact rated to 5 A at 125 VAC and an IP67-sealed housing for dust and water protection in harsh environments. The switch uses a roller plunger actuator and accepts screw-terminal connections on a chassis-mount footprint. Compare the full model, actuator travel, mounting and terminal arrangement before replacement.

• Model & fit: Matches D4E series part D4E-1D20N roller-plunger small sealed limit switch for position detection and end-stop sensing.
• Electrical rating: SPDT (1NO/1NC) snap-action contact rated to 5 A at 125 VAC for general-purpose resistive loads.
• Ingress protection & durability: IP67 sealed housing for dust-tight and temporary immersion protection; series datasheet life ratings indicate long mechanical and electrical life.
• Actuator & mechanics: Roller plunger actuator with snap-action mechanism for positive switching; standard D4E chassis-mount footprint and screw-terminal connections for straightforward replacement.
