De Dietrich 95317384 4-pin Wieland male connector

This 4-pin Wieland male connector is listed under the De Dietrich brand for use in boiler and burner electrical systems. It belongs to the category of plugs and connectors that carry low-voltage signals and mains supply between the control board and driven components such as the fan, gas valve, or ignition transformer. The connector type is defined by its series (Wieland), pin count (4), and gender (male). When selecting a replacement, the critical parameters are the connector series and pin count, the conductor cross-section it can accept, the insulation temperature class, and the terminal type. The keying of the housing must also match the female counterpart to ensure correct orientation. Poor contact in such a connector can reproduce almost any electrical fault symptom, making it a routine suspect during troubleshooting. When replacing, verify that the existing wiring uses the same pin arrangement and that the connector body locks securely.
