In industries where power delivery must remain uninterrupted despite environmental challenges—whether it’s a dusty construction site, a windswept telecom tower, or a sealed medical device enclosure—reliable connectivity is non-negotiable. To meet that need, L-com is proud to announce the addition of Bulgin’s 7000 Series IP-rated circular power connectors to our inventory. Renowned for their rugged construction and long-term dependability, these connectors deliver sealed power solutions for critical applications in oil and gas, marine underwater, buildings and construction, industrial automation, and recreation water systems.
With four robust product groups—including flex cable connectors, inline cable connectors, front panel mount connectors, and accessories—L-com now offers customers access to a field-proven solution built for demanding power connections where environmental protection is crucial. This blog will walk you through what each product group offers, how they function in the field, and what features might make them an ideal addition to your industrial or mission-critical installation.
Why the Bulgin 7000 Series?
The Bulgin 7000 Series is known for its IP66, IP68, and IP69K ratings when mated, meaning it protects against water, dust, and high-pressure washdowns. These connectors also provide quick-disconnect functionality, which simplifies maintenance and system upgrades while ensuring secure and reliable power connections. For customers working in environments where traditional connectors fail due to moisture ingress, these ruggedized connectors offer peace of mind and long service life.
Whether you’re working in topside/subsea oil and gas, marine underwater, buildings and construction, industrial automation, or recreation water systems, these connectors stand up to the challenge. Below, we break down the benefits of each of the four product groups now available from L-com.
1. Flex Cable Connectors: Mobility Meets Durability
The flex cable connectors in the 7000 Series are designed for situations where flexibility, portability, and movement are part of the installation environment. These connectors are terminated onto flexible cables and are ideal for mobile equipment, outdoor surveillance units, or any rotating or portable device where power must be securely delivered in variable positions.
Imagine a mobile surveillance trailer deployed for public safety at an outdoor event. Its cameras and comms systems require power connectors that won’t degrade from exposure to rain, wind, or frequent transportation. Bulgin’s flex connectors ensure a water-tight, durable connection that’s easy to deploy and stow.
Key Features:
-
IP66/IP68/IP69K sealing (when mated) for outdoor use
-
Threaded coupling for a stronger hold
-
Available in multiple pole configurations to meet varied power requirements
2. Inline Cable Connectors: Power When You Need It, Wherever You Are
The inline cable connectors allow two cable-mounted connectors to be mated together, enabling longer cable runs or in-line power connections. These are ideal for scenarios where systems must be extended or reconfigured without full teardown—such as in topside/subsea oil and gas or industrial automation.
Picture a coastal oil platform where new sensor modules need to be installed along a catwalk extending over the water. Rather than replacing the entire power system, engineers use Bulgin inline cable connectors to create watertight junctions that extend existing cabling. These rugged connectors stand up to salt spray, high winds, and maintenance foot traffic while keeping power flowing to critical safety and monitoring systems.
Key Features:
-
Rugged, UV- and impact-resistant bodies
-
Designed for simple field assembly
-
Ideal for extending power cabling in outdoor or semi-permanent systems
3. Front Panel Mount Connectors: A Secure Interface for Fixed Installations
Designed for fixed installations where equipment requires a robust panel interface, the front panel mount connectors provide a sealed connection point built into control boxes, distribution panels, and electronic enclosures. These are ideal for topside/subsea oil and gas, marine underwater, buildings and construction, industrial automation, and recreation water systems, where controlled environments demand dependable and tamper-resistant power input/output.
Consider a marine research vessel outfitted with environmental monitoring equipment. Each instrument panel inside the ship’s sealed equipment bay uses Bulgin front panel mount connectors to route power through bulkheads. The connectors deliver dependable energy to data loggers and sonar units while resisting the vibrations and moisture common in ocean-going applications.
Key Features:
-
Panel-sealed to prevent ingress at enclosure interfaces
-
Rear screw terminations for solid internal connections
-
Threaded connection to prevent accidental disconnects
4. Accessories: Protection and Installation Made Easy
No connector system is complete without the accessories that ensure its integrity and ease of use. The Bulgin 7000 Series accessories include:
-
Sealing caps for flex, inline, and front panel connectors to maintain IP ratings when the connection is disengaged
-
Gland packs, including cable glands, cages, and gland nuts to ensure cable entry points remain sealed and secure
These components ensure complete system protection, especially in standby or maintenance scenarios, and support a smooth installation experience.
