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:
Standardised 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:
Flow Meters
Hydraulic and Pneumatic Actuators
These connectors ensure a reliable and standardised 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, VDR surge protection, Rectifier or ATEX)
