Introduction

DIN valve (solenoid) connectors are an essential component in many different types of systems and devices, including control systems, machinery, and equipment. These connectors are designed to provide a secure and reliable connection between the valve and the control system, enabling the flow of electricity, air, or other media to the valve. However, not all DIN valve connectors are the same, and it is important to select the right connector for your application. In this blog post, we will provide a selection guide for DIN valve connectors, including the different types of connectors, their features and benefits, and how to choose the right connector for your application.

What is DIN Standard:

The term DIN stands for Deutsches Institut fur Normung e.V. The electrical DIN connector was originally standardized in the early 1970s by the German National Standards Organization. DIN is a widely known standard for connectors and enclosures

The standardized term DIN connector does not refer to any specific type of connector without an associated number. The standard naming system used to represent the DIN connector is DIN 43650 connector, such standards enable the manufacturer and consumer to navigate multiple DIN connector standards with ease and convenience. DIN 43650 connectors are also known as the EN 175301-803 standards.

Micro-DIN connectors are available in smaller sizes, but they are very alike to their larger and older ones. DIN connectors belong to a family of multi-pin electrical connectors. The ISO 44 counterparts 00 stands for the standards which are set by the International Organization for Standardization, which are exclusively made for electrical connectors. The DIN connectors can be used with either hydraulic or pneumatic solenoid valves.

Types of DIN Connectors:

There are three main types of DIN valve connectors – Form A, Form B, and Form C. Each type of connector has its own unique features and benefits, and it is important to choose the right type of connector for your application.

1. DIN EN 175301-803 Form A (formerly known as DIN 43650 Form A)
2. DIN EN 175301-803 Form B (formerly known as DIN 43650 Form B)
3. DIN EN 175301-803 Form C (formerly known as DIN 43650 Form C)

Form A (DIN EN 175301-803 Form A Connector)

The name Form A in this standard of connectors refers to the distance between the pins. As seen in figure 1, the distance between pins 1 and 2 is 18 mm, as standard for Form A connectors. However, there is no difference between 2- and 3-pin connectors. The standard defines the distance between pins 1 and 2, while pin three is the earth connection.

Form A

These connectors are designed to be used with solenoid valves in hydraulics and pneumatics applications to securely supply power using a water-resistant method.

Form B (DIN EN 175301-803 Form B Connectors)

Form B

Form B DIN connectors for solenoid valves are also called micro connectors. Two main differences set them apart from the Form A connectors.

Firstly, they have a smaller space between the pins, and the connectors can also have two different pin spacings: 10 mm and 11 mm. The 11 mm DIN connectors have three flat blade contacts and are the most common. The 10mm DIN connectors have one flat blade and two U-shaped pins pointing outward, as seen in figure 2. Similarly, to Form A valve connectors, Form B valve connectors can be found on solenoid valves in hydraulics and pneumatics applications, as well as in marine applications.

Form C (DIN EN 175301-803 Form C Connectors)

Form C DIN EN 175301-803 connectors are even smaller than the Form B connectors and are often called the sub-micro connector. As with the Form B connectors, these also come in two sizes under the standard. These are the 8 mm and the 9.4 mm, where the 8 mm has two pins plus earth, and the 9.4 mm has three pins plus earth.

Form C

Form C DIN connectors are primarily used with solenoid valves offering a secure and water-resistant method for applying power. The Din 43650 connectors can be found in hydraulics and pneumatics applications as well as marine applications, pressure sensors and switches, and optical, limit and proximity switches.

Applications:-

The application of DIN connectors can be found in a diverse range of electrical products such as in conjunction with pneumatic devices, hydraulics machines and machinery, and electromagnetic devices, including solenoid valves. DIN connectors are utilized in a sizable proportion of electrical and electronic solutions such as proximity switches, pressure transducers, and level sensors, including low-energy motors and limit switches.

These DIN connectors consist of additive benefits such as improved product performance, simplified manufacturing processes, and reduced inventory, which eventually leads to decreased application costs. DIN connectors have met different overvoltage protection requirements and are also made to function within certain voltage limits.

Elcom’s DIN connector is heavily used in dusty, oily, or humid environments. Additionally, these connectors can serve DC current, AC current, and specified voltage requirements. Elcom’s DIN connectors also provide connector modification options which include modification of indicator lights and modification of surge suppression.

Features

● Connectors come in various “Forms” depending on the configuration of pins and dimensions. The Forms carried out by Elcom are listed below.
○ DIN 43650 Form A (ME / HD): – Connector has an 18mm contact separation.
○ DIN Form B: I/S (Industrial Standard) Form B (MER): – Connector has an 11mm contact separation and is commonly referred to as Industrial Standard Mini.
○ DIN 43650 Form C (MEM): – Connector has an 8mm contact separation and is commonly known as a “sub-micro” connector.
○ Industrial Micro-Mini (ISO Form C) (MEM):- Connector has a 9.4mm contact separation and is commonly known as the Industrial Standard Sub-Micro.
● Standard internal thread DIN valve connectors are IP65 rated and available with different thread styles, gaskets and circuitry options.
● Standard options include LED illuminated devices as well as VDR (voltage-dependent resistors), diodes or transit diodes (with or without the illuminated device) to offer protection against overvoltage peaks.
● IP-65 is available for Metal Enclosure (ME), HD & MER
● Elcom offers various options for modifying the connectors including
○ Indicator lights
○ Surge suppression
○ UL-94 V-2/V-0 flammability rating available
