TE Connectivity Circular Connectors

Circular connectors are a cornerstone of reliable power, signal, and data transmission in industrial, transportation, energy, and automation applications. Designed for fast mating, secure locking, and durability in harsh environments, they offer a compact and efficient way to manage complex interconnect needs. Within this space, TE Connectivity stands out as one of the most trusted manufacturers, offering one of the broadest circular connector portfolios available today.

Available widely through DigiKey, TE Connectivity circular connectors are among the most frequently selected solutions for engineers and designers who demand performance, flexibility, and global support.

The circular interface provides several advantages. It allows quick connect and disconnect without special tools, distributes mechanical stress evenly, and supports robust sealing against dust, moisture, and vibration. TE Connectivity circular connectors are designed to meet these demands across signal, power, and hybrid configurations and supporting applications ranging from factory automation and robotics to transportation, medical devices, and defense systems. With options for plastic or metal shells, multiple locking mechanisms, and IP‑rated sealing, TE’s circular connectors are engineered to perform where rectangular connectors often fall short.

With so many options, sometimes it is hard to figure out exactly what you need, so let’s deep dive into some of these products.

One of the most popular and widely used families is TE Connectivity’s Circular Plastic Connectors (CPC). Known for their versatility and cost‑effective durability, CPC connectors support signal, power, or combined signal‑and‑power configurations within the same housing. Available across multiple series, including Series 1, 2, 3, 4, 5, and 6 and miniature. CPC connectors can handle currents up to 50 A per contact and offer IP67 sealing options for environmental protection.

CPC connectors are frequently used in industrial machinery, HVAC systems, medical equipment, lighting, and transportation applications, making them a consistent top seller on DigiKey.

For factory automation and sensor‑actuator connectivity, M8 and M12 circular connectors are among the most purchased TE Connectivity products. These connectors are designed for compact spaces while delivering reliable, vibration‑resistant performance. TE’s M12 connectors support multiple coding’s (A‑, B‑, D‑, and X‑coded) to enable signal, data, and high‑speed Ethernet connectivity in industrial environments.

With IP67 and IP68 sealing options and standardized interfaces, M8 and M12 connectors are ideal for automation, robotics, and industrial Ethernet installations.

If you have an application that requires extreme environmental durability, TE Connectivity DEUTSCH circular connectors are a go‑to solution. These connectors are widely used in off‑highway equipment, heavy‑duty transportation, military, and aerospace applications. DEUTSCH connectors provide high vibration resistance, secure locking mechanisms (bayonet, threaded, or push‑pull), and long‑term reliability under harsh conditions.

Their rugged construction and broad configuration options make them especially attractive for mission‑critical designs. HD30 Connectors are constructed in an aluminum shell to meet the needs of truck, bus and off-highway industry applications. HDP20 Connectors are for harsh environments such as construction, mining, marine and agricultural industries.
