DIN 43650 Electrical Connectors for Solenoid Valves – Technical Overview

DIN 43650 electrical connectors**, also known as **form connectors** or **solenoid valve connectors**, are critical components in industrial automation and fluid control systems. These connectors are specifically engineered to provide secure and efficient electrical connections to **solenoid valve coils**, commonly used in pneumatic and hydraulic applications.

Most **IP65-rated industrial solenoid valves** are either pre-equipped with or require a compatible **DIN 43650 connector** to interface the power supply cable with the coil's electrical circuit. These connectors offer a robust and standardized method of connection that ensures resistance to dust, moisture, and vibration, making them ideal for harsh operating environments.

Key Features of DIN 43650 Connectors:

Standardized Form Types**: Available in Form A, Form B, Form B-Industrial, Form C analogue and Form C micro, each type varies in pin configuration and dimensions to suit different solenoid valve and sensor applications.

Voltage Compatibility**: Designed for AC and DC voltage applications, typically ranging from 12V to 240V.

Ingress Protection**: Most connectors offer **IP65 to IP67** protection when correctly installed with gaskets and screws.

Internal Circuit Options**: Some models include integrated circuitry such as LED indicators, surge suppression (varistors or diodes), and rectifiers to enhance electrical performance and protect the coil.

Material Construction**: Housings are typically moulded from high-grade polyamide (PA) for chemical resistance and mechanical durability, with nickel-plated brass or stainless-steel cable glands.

Applications:

DIN 43650 connectors are widely used in:

**Solenoid Valves**

**Pressure Sensors**

**Flow Meters**

**Hydraulic and Pneumatic Actuators**

These connectors ensure a reliable and standardized electrical interface that simplifies maintenance and reduces downtime in automated systems.

Choosing the Right Connector:

When selecting a **DIN connector for a solenoid valve**, consider the following:

**Connector Form (A, B, C, etc.)**

**Pin configuration (2+PE or 3+PE)**

**Operating voltage and current**

**Environmental sealing requirements (IP rating)**

**Optional electronics (LEDs, surge protection)**
