Solenoid connectors connect solenoid valves to a variety of other system components, including power supplies, control devices, sensors, and transducers. Its basic design is divided into three types: Type A, Type B and Type C according to DIN EN 175301-803. The construction of these three connector types is briefly described below, along with an overview of the circuit functions that work with the solenoid connector. By reading our review article, you will be able to learn more about solenoid valves.
Solenoid Connector Type
Form A connectors are the largest among the standard types. They feature a square housing with pins spaced 18 mm apart. Typically, they have two or three pins, including a ground connection. These connectors are commonly used in industrial applications where space is less constrained.
Form B connectors, often referred to as micro connectors, are more compact. They have rectangular housings with pin spacings of either 10 mm or 11 mm. The 11 mm variant usually includes three flat-blade contacts, while the 10 mm version has one flat-blade and two U-shaped pins. Their smaller size makes them suitable for applications with limited space.
The smallest standard connectors, Form C connectors, are also known as sub-micro connectors. They have square housings with pin spacings of 8 mm or 9.4 mm. Typically, they feature two or three pins, including ground. Their compact size is ideal for applications where minimizing space usage is essential.
Key Factors to Consider When Choosing a Solenoid Valve Connector
1. Electrical Compatibility
The most important factor when choosing a solenoid valve connector is ensuring it’s compatible with your solenoid valve’s electrical requirements. Pay close attention to the voltage and current ratings of both the connector and the valve. Different solenoid valves may operate at different voltages (AC or DC), so it’s essential to select a connector that matches these specifications to avoid overheating, electrical faults, or system malfunctions：
-
Type A: rated voltage up to 250V, rated current up to 16A
-
Type B: rated voltage up to 125V, rated current up to 10A
-
Type C: rated voltage up to 125V, rated current up to 6A
2. Environmental Factors
Consider where your solenoid valve system will be installed. Is it exposed to moisture, dust, extreme temperatures, or other harsh conditions? Explosion-proof or flameproof connectors might be necessary for hazardous environments.Consider connectors with IP ratings that reflect their resistance to dust and water ingress (e.g., IP65 for dust-tight and water-resistant applications).
3. Durability and Material
The durability of the connector is vital, especially for systems in high-stress environments. Choose connectors made from high-quality, durable materials such as stainless steel or reinforced plastics, which can resist wear, chemicals, and temperature fluctuations. A durable connector will withstand the test of time, reducing the frequency of replacements and ensuring long-term performance.Generally, Type A, B, and C connectors have an operating temperature range of -40 °C (-40 °F) to 125 °C (257 °F). The range varies by manufacturer.
4. Size and Compatibility
Connector size is an important consideration, especially if you have limited space in your system. M12 connectors are compact, making them perfect for systems where space is tight. However, if space is not a concern, DIN 43650 connectors are a reliable and widely-used option. Also, make sure the connector is physically compatible with your solenoid valve. This includes checking for the correct pin configuration and ensuring that the connectors and fittings are aligned with the valve’s requirements.
5. Ease of Installation and Maintenance
Ease of installation and ongoing maintenance should also factor into your decision. For systems requiring regular reconfigurations or replacements, a Eurofast connector might be the best choice because of its quick-connect feature. For systems that don’t need frequent maintenance, a DIN connector can offer a more permanent solution. The easier it is to install and maintain the connector, the less downtime your system will experience.
6. Thread Type
Different connectors have different thread types for solenoid valve connector wiring:
-
Type A: PG 9, PG 11, M16, and NPT 1/2 in
-
Type B: PG 9 and NPT 1/2 in
-
Type C: PG 7
Which Type of Solenoid Valve Connector Should You Choose?
When choosing the basic type of solenoid valve connector to purchase (Type A, Type B, and Type C), there are several factors to consider, including your application needs, how you connect them, and the characteristics of your equipment. Here are some guidelines for selection:
Type A Solenoid Connector:
Applicable scenarios: Type A connectors are often used to connect solenoid valves to controllers, control panels, or other equipment.
Advantages: Type A connectors are more common and suitable for common connection needs. The design of the header pins can be customized for specific applications.
Considerations: If you need to connect a solenoid valve to a control system or panel, Type A connectors may be the more common choice.
Type B Solenoid Connector:
Applicable scenarios: B-type connectors are usually used in the solenoid valve itself to connect with piping systems or other equipment.
Advantages: The B-type connector can ensure the safety of the external connection of the solenoid valve and prevent misoperation.
Considerations: If you need to make a connection between the solenoid valve and the piping system, type B connectors may be better suited as they provide additional protection and robustness.
Type C Solenoid Connector:
Applicable scenarios: C-type connector is a combination connector, which is suitable for ensuring the correct correspondence between the plug and the socket, as well as the stability of the connection.
Pros: The Type-C connector ensures that the plug and receptacle are properly mated, avoiding the problem of plugging in the wrong pin.
Considerations: Type-C connectors can be a valuable option if you want to ensure proper mating when connecting, as well as prevent misconnection problems.
To sum up, the type of solenoid valve connector should be selected according to the specific application. You need to consider factors such as the type of equipment connected, environmental conditions, whether the degree of protection is required, the matching of plugs and sockets, and so on. Further consultation with the connector supplier or manufacturer is recommended prior to purchase to ensure you have selected the connector type that best suits your application needs.
