DIN 43650 Electrical Connectors for Solenoid Valves
Comprehensive guide overview of DIN 43650 connectors
DIN 43650 connectors, also known as EN 175301-803 connectors, are standardised electrical connectors commonly used to connect solenoid valves to power sources. They are designed to provide a secure and water-resistant connection in various industrial applications, including hydraulics, pneumatics, and marine environments.
Types of DIN 43650 Connectors
There are three primary forms of DIN 43650 connectors, each differing in size, pin configuration, and application suitability:
Form A (DIN EN 175301-803 Form A)
Pin Spacing: 18 mm
Pin Configuration: 2 or 3 pins plus ground
Housing Shape: Square (28 mm x 28 mm)
Applications: Ideal for general-purpose solenoid valves in hydraulics and pneumatics
Features: Available with or without circuitry, including options for LED indicators, surge suppression (VDR), and bridge rectifiers
Protection Rating: Up to IP67, depending on the model
Form B (DIN EN 175301-803 Form B)
Pin Spacing: 10 mm analogue or 11 mm Industrial
Pin Configuration: 2 pins plus ground
Housing Shape: Rectangular
Applications: Suitable for space-constrained installations, such as manifold banks
Features: Options include LED indicators and surge protection
Protection Rating: Up to IP67
Form C (DIN EN 175301-803 Form C)
Pin Spacing: 8 mm analogue or 9.4 mm Micro
Pin Configuration: 2 or 3 pins plus ground
Housing Shape: Square (smaller than Form A)
Applications: Used in compact devices like pressure sensors and proximity switches
Features: Available with LED indicators and surge protection
Protection Rating: Up to IP67
Wiring and Installation Guidelines
Proper wiring and installation are crucial for the reliable operation of DIN 43650 connectors:
Polarity: Connect the positive power supply (typically red or brown wire) to terminal 1, and the negative return (black or blue wire) to terminal 2.
Cable Entry: Ensure the cable entry faces downward to prevent water ingress.
Strain Relief: Use the appropriate cable diameter for the connector's PG rating to achieve a tight seal.
Torque Settings: Adhere to recommended torque settings to maintain IP protection:
Strain relief nut: 1.8 N·m ±10%
Central fixing screw: 0.4 N·m ±10%
Contact screws: 0.2 N·m ±10%
