What is a 3-pin plug?
This is a connector for connecting devices in an electrical circuit. This plug has three contact points: phase, neutral, and ground.
Pin configuration
| Pin | Functie | description |
|---|---|---|
| Pin 1 | Phase (L) | The phase pin carries the current from the power source to the device. This is the active pin in the circuit. |
| Pin 2 | Neutral (N) | The neutral pin carries the current back from the device to the power source and completes the circuit. |
| Pin 3 | Earth (PE) | The phase pin carries the current from the power source to the device. This is the active pin in the circuit. |
When is a 3-pin plug used?
A 3-pin plug is used when the electrical function does not require extensive wiring, such as with single lights or sensors. In situations where the additional functions and connections of a multi-pin plug or connectors are not needed, the 3-pin plug offers an efficient and cost-effective solution.
Vignal Group connectors are also known for their high quality and reliability, similar to Deutsch connectors. These are two popular brands for commercial vehicles, agricultural machinery, and industrial applications.
Agricultural machinery
Applications: Lighting, sensors, hydraulic control systems
Reason for use: Agricultural machinery is often exposed to harsh conditions such as dirt, moisture, and vibrations. A 3-pin plug is used here for single lighting or signaling equipment such as a single work lamp on a tractor
Off-road vehicles
Applications: Lighting, electronic accessories, navigation and communication equipment
Reason for use: Off-road vehicles operate in harsh conditions where reliable electrical connections are crucial. Deutsch and Vignal connectors are chosen for their robust design and waterproofing.
Off-road vehicles
Toepassingen: Verlichting, besturingssystemen, sensoren, communicatiesystemen
Reden voor gebruik: Bouwmachines werken in zware omgevingen en hebben betrouwbare en duurzame elektrische verbindingen nodig. Deutsch en Vignal connectoren zijn ideaal vanwege hun hoge beschermingsgraad tegen stof en water, evenals hun weerstand tegen trillingen en schokken.
Advantages of a 3-pin plug
Suitable for simple applications where only three electrical connections are needed. Takes up less space and is cost-effective.
