OL11 IP67 Waterproof 2–5 Pin Circular Connector

The OLINK OL11 Series is a compact IP67 waterproof circular connector available in 2-, 3-, 4-, and 5-pin configurations. It includes cable-mount plugs, inline cable connectors, and rear-nut panel-mount receptacles with male-pin or female-socket contacts. Gold-plated brass contacts, solder termination, threaded coupling, and a sealed housing provide reliable connections for compact outdoor and industrial equipment.
When properly assembled and mated, the OL11 connector provides IP67 protection against dust and temporary water immersion.

Compact IP67 Construction

The OL11 combines threaded coupling, O-ring sealing, and a cable seal to maintain a secure mechanical and environmental connection. Gold-plated brass contacts support reliable electrical conductivity, while the PA66 housing provides a compact and durable structure for space-limited installations.

Cable-to-Cable and Cable-to-Panel Options

The OL1110 cable-mount plug can be paired with either the OL1111 inline cable connector or the OL1112 rear-nut panel receptacle. Pin and socket contacts are available on either mating side, allowing flexible cable-to-cable and cable-to-panel configurations.

Always select mating connectors with the same pin count and compatible contact arrangement.

Select the Correct Pin Configuration

Choose the pin count according to the required circuit, rated current, rated voltage, and wire size. The 2- and 3-pin versions are rated at 5 A and 180 VAC, while the 4- and 5-pin versions are rated at 3 A and 125 VAC.

The maximum recommended wire size is 0.75 mm² / 18 AWG for 2- and 3-pin versions and 0.5 mm² / 20 AWG for 4- and 5-pin versions.

Model Dimensions and Installation Requirements

Review the connector dimensions before cable assembly or enclosure design. The OL1110 cable plug and OL1111 inline connector accept cables with an outer diameter of 4–6.5 mm.

For panel installation, the OL1112 rear-nut receptacle requires an Ø11 mm panel cutout, an M11 × 1 mounting thread, and a maximum panel thickness of 3.5 mm.

Solder Termination Wiring

OL11 connectors use solder termination for secure conductor-to-contact connections. Before soldering, slide the compression nut, cable seal, and back shell onto the cable. Strip and prepare each conductor, match it to the correct pin number, and solder the contact without creating bridges between adjacent terminals.

Verify the pin assignment and polarity before reassembling and tightening the connector. Wiring should be completed with the power disconnected and by qualified personnel.

Applications for Compact Low-Current Connections

The OL11 Series is suitable for compact power, signal, sensor, lighting, and control connections used in marine equipment, automotive auxiliary systems, industrial machinery, outdoor lighting, and renewable-energy equipment.

For solar and renewable-energy systems, the OL11 is intended for monitoring, control, or auxiliary circuits within its specified 3 A or 5 A electrical rating.

OEM / ODM Customization

OL11 products can be customized according to project and production requirements. Available options include blue-and-black or all-black housings, cable length and wire size, pre-wired cable assemblies, custom wire harnesses, product logos, identification labels, and branded packaging.

Please provide the required connector model, pin assignment, cable specification, cable length, quantity, and packaging requirements for technical evaluation. Customization availability depends on the selected model, order quantity, and technical feasibility.
