UL Rated Panel Mount Connectors
Panel Mount is a feature built into the design of a connector half that allows it to be secured to an external equipment panel or case. This is different to cable connectors that have male and female connectors that freely mate with each other.
This is also not the same as PCB board mount where the terminating leads of the connector are used to mechanically fasten it to a circuit board via a hole or surface mount. This reduces stress on the electrical solder connections.
UL is a worldwide safety organization that inspects and tests electrical equipment to ensure it meets its own standards. Certification to UL standards reduces the risk of equipment not being accepted in an installation by a local authority having jurisdiction (AHJ). Choosing a connector with the appropriate UL ratings is important for your project.
Panel feed-through connectors, also known as bulkhead or panel mount connectors, are used to feed wire and cables into an enclosure, such as an electronic cabinet, power supply, or machine. They are typically designed to be sealed against the elements and can be used with power, signals, thermocouple, fiber optics, and pneumatic/fluidic media.
The Neutrik NC4FD-L-B-1 XLR 4-pole female audio receptacle is a panel mount connector that accepts 16 gauge/AWG cable and has gold contacts. It has a black finish housing and solder cups and is rated to IP 40. It is easy to assemble, simple to use, reliable, and robust. It is backed by the superior quality materials and workmanship of the Neutrik brand and decades of industry excellence. This product is a great choice for your next project. Note: This connector does not have a breaking capacity and should never be disconnected or unplugged under load.
The IP67 dust-tight connector is a great choice for harsh environment applications. These rugged RJ45 ethernet jacks feature a gasket seal to keep unwanted dirt, dust, and moisture out of the connection. They are also water rated 4 pin panel mount connector to work up to 30 minutes after being submerged in 1 meter of water.
These waterproof connectors are commonly used in industrial automation and sensors, robotic control systems, data logging, and avionics equipment. They can withstand harsh operating stresses such as extreme hot or cold temperatures, shock and vibration, corrosion, and dirt or dust ingress. Many manufacturers offer a variety of industrial grade waterproof connectors, with different types of housings, mating mechanisms, and pin configurations.
Some of the most common types of industrial waterproof connectors are circular connectors. These are usually mounted on an enclosure to prevent water and dust from infiltrating the device’s internal circuits. They are often made of plastic composites or metals with a protective coating to prevent damage from environmental factors.
The TE Connectivity AMP SEAL-D series of connectors is an industry-standard form factor that incorporates both signal and power contacts in one unit. They have a waterproof rating of IP67 (dust-tight and immersion to one meter) and come in both vertical and right-angle designs. They maintain the same footprint as standard unsealed d-sub connectors, eliminating the need to change PCB and sheet metal designs for upgrades to harsh environments.
Temperature Range: -40°C to 85°C
Whether used in a machine tool, robotic system or industrial plant, connectors face a wide range of environmental stresses that can damage them. These include mechanical shock, vibration and abrasion; chemical exposure to harsh materials such as salt water or corrosive chemicals; and electrical stress caused by temperature variations and transients. Connectors must be able to withstand these stresses in order to deliver reliable and consistent performance that maximizes manufacturing uptime and productivity.
Some connectors are designed for high temperatures and offer a choice of mating styles to accommodate various applications. For example, some thermocouple connectors feature a Zero Insertion Force (ZIF) design that uses levers to bring the male and female mating pins into contact with each other after they’re mated. This significantly reduces the insertion force to a fraction of what would be required with conventional screw-in or spring pin contacts.
Another option is a circular push-pull connector that offers a robust waterproof cable-to-panel and PCB interface. These ruggedized connectors waterproof plug and socket connector are ideal for telematics systems in transportation and control systems, automated doors and ramps, sensor connectivity and many data and communication device applications. They’re available in a wide range of standard and miniature body designs to meet specific application requirements, with various pin counts and signal/power options. Other connector families for telematics applications include VULCON M-series circular push-pull connectors with screw threads; Power-D and Combo-D connectors that combine signal and power contacts in the same connector; and TE Connectivity’s SEAL-D IP67 waterproof connectors.
Voltage Range: 250V
When considering the power handling capacity of a panel mount connector, it is important to review the maximum voltage that will be encountered on the connection. This will help ensure that the connector is capable of providing ingress protection to prevent damage to other components and devices within the project. It is also important to consider the amount of current that will be handled by the connector as well.
When reviewing the specifications of a particular connector, it is also helpful to determine what sort of environment the connection will be operating in. This includes things like vibration, kinetic shock, EMI shielding, environmental ingress (dirt, water, grease), and chemical/solvent exposure. These factors will impact the overall choice of a panel mount connector.
Panel mount refers to features built into a connector half that allow it to be fixed into an external case or equipment panel. This typically involves having a cut-out on one side of the enclosure, with the connector sitting in it and the inside electronics wired to it. Most of the time, connectors that have panel mount features are cable connectors and will include both a front panel mounting and a rear panel mounting.
Surface mount termination – These items have leads that are designed to be placed onto pads on the surface of a PCB that are then soldered in place by hand or using re-flow or wave soldering methods. These types of connections are usually a through hole, but some can be pressed fit.
