D4N Series Limit Switch D4N-4B20R Roller/Plunger Actuator

This listing is for a D4N-4B20R limit switch from the D4N family, supplied as a single unit. The D4N family uses compact chassis-mount bodies with roller or plunger actuator heads for reliable position detection and machine limit signaling. Distributor and supplier references show D4N-series variants with mechanical life ratings around 1,000,000 operations and family electrical ratings reported up to 10 A (AC) and 2.5 A (DC) for comparable submodels; contact arrangement and exact electrical ratings vary by specific D4N submodel. Before installation, compare mounting holes, actuator style (roller/plunger), terminal type, and the printed model code on the part to ensure correct fit and contact configuration. If precise electrical or dimensional specifications are required, consult the D4N-4B20R datasheet or the seller for the exact submodel details.

• Fits D4N series applications - select the D4N-4B20R variant for roller/plunger-style actuator fit; verify printed part code before installation.
• Miniature chassis-mount limit switch for position sensing and machine limit detection in automation equipment.
• Typical D4N family electrical capability noted on distributor listings (example: up to 10 A AC, 2.5 A DC on some submodels); confirm exact current/voltage and contact arrangement for D4N-4B20R from the datasheet.
• Durable mechanical performance documented for D4N family (mechanical life commonly listed as 1,000,000 operations minimum on supplier pages); vibration and shock ratings vary by submodel.
• Includes: one limit switch (D4N-4B20R) - confirm terminal type and contact configuration match your equipment prior to ordering.
