Advantages and Disadvantages of 4 Pin Panel Mount Connectors

Connectors are an essential part of most electronic projects. There are several different types of connectors, each with its own advantages and disadvantages.

Some are panel mount, which allows them to be fixed to the back of a panel or enclosure. This helps to reduce strain on the fragile electrical connections.

Panel Nut

Panel mount is a feature built into the design of a connector half that allows it to be secured to a panel, external case or enclosure. Often (but not always) this type of connector is a cable connector.

There are many different variations of this connector style – the most common are the DB-15 and DB-25 varieties that can be male or female depending on the pin and socket configuration. These are also known as ‘D-subminiature’ connectors and are one of the most popular computer connector types.

The leads on the termination side of these items are designed to be surface mounted and soldered to a PCB using re-flow or wave-soldering techniques. They have the advantage of lower stress on the terminations than their through hole counterparts.

Connectors are typically designed with an insulator that encapsulates the pins and sockets in order to protect them from each other and the shell. It also serves to provide 4 pin panel mount connector alignment when mating the two connector halves. The insulator is often a plastic material such as polystyrene or polyethylene.

Connectors may also have features that allow them to be ‘locked’ in place or removed without the need for special tools. These can include jam nuts, hex studs or keyed contacts. There are also a variety of other accessories available for these types of connectors.

Strain Relief

If you want to protect your wiring connections from external strain, panel mount connectors are the answer. You can use them to connect and disconnect wires without worrying about a stress cracking a solder joint or breaking the connector. They also provide a level of tamper-resistance that you cannot get from other types of connectors, making them safe to use in devices that have untrained users.

You can use them to feed cable into a device from the back, or to add a power terminal on a panel or enclosure wall. Using the solder cup connection system, you can easily connect stripped and tinned cables by inserting them into the connector and applying heat to the solder points. The connectors are keyed to prevent incorrect connections and come with internal gaskets that seal to provide protection against environmental ingress.

A panel nut is installed on the connector, and it allows you to secure the connector to the enclosure or panel wall. The nut is threaded and can be screwed in or out to remove the connector from the panel. It is a good idea to keep a supply of spare nuts on hand, so you can replace one if it becomes damaged. The panel nut also has a built-in strain relief that eases the tension placed on wires connected to the terminals.

Keyed

Many electrical connectors have the ability to be keyed. This feature helps to prevent incorrect mating that could result in mechanical damage, signal loss or even a short circuit. It also prevents the use of a wrong type of connector in an application. It takes several forms, but most often a protruded piece of material is created on one connector that matches with the shape of the hole in the other. This protrusion is named a “key” because it resembles the shape of a key and is designed to fit in the hole that matches it.

Having a keyed connector can make it much easier to assemble the connections on a PCB. This will reduce the risk of errors during assembly and installation because it’s physically impossible to mate the connectors incorrectly. In some cases, this is done in conjunction with polarization. Polarization is helpful if the connectors are identical and can help the assembly operator quickly find the correct pair.

However, polarization and keying can add weight to a connector depending on the connector range and may take up space on the PCB footprint and possibly space above it. These features can also increase the cost of the basic connector. They also require manual preparation on the connectors which could add to the overall processing time and cost of the project.

UL Approved

UL approval is the standard for electrical connectors in North America. A device that does not have a UL approval runs the risk of being rejected by the authority having jurisdiction (AHJ). UL certifications reduce this waterproof connector manufacturer risk and allow for a quicker time to market for products.

Unlike cable connectors, which are mounted with screws to the PCB and enclosure, panel mount connectors are fixed in a specific cut-out in the enclosure, using glue or other adhesive methods. They do not put any mechanical strain on the solder connections inside the connector, which can increase the life of the circuit board and the cable connectors that connect to them.

This panel mount connector is a male receptacle, with screw locking, and a pin count of 4. It meets the protection class IP67. This means that it is dust-tight and offers protection against contact and temporary immersion up to one meter water depth. The housing is made of PA66+30% GF, which makes it resistant to chemicals, oils, and acids.

The connector is designed to be easy to use, with a simple plug and play design. This allows users to plug in and out of the connector without having to align it precisely, and it also prevents mis-plugging. The connector has a built-in magnetic adsorption, which will automatically connect the male and female part to form a stable connection.
