M12 · Design intent

From sensor signals to small controller power, start by choosing the right interface for limited space.

M12 combines a compact form with common connection configurations. Threaded or push-lock, cable or panel mount—start from the device's installation space, then select the contact count.

LLT · Environmental protection

Water stays out.Connected inside.

Compact controllers and sensors also need complete sealing. From the compact mating interface to the cable exit, moisture stops outside the connection.

IP67Applicable per selected configuration

Protection applies only after correct mating, locking, and cable sealing are complete. The imagery is an environmental illustration, not footage of actual testing. Applicable conditions ↗

Connection method

See how it locks first, then how it mounts.

The mating structure determines the locking method; the mounting form determines how the interface lands on the device. Select the two separately, and review appearance and configuration together.

Appearance photos identify the mounting and coupling structure. Male contacts, female contacts and housing forms are labeled separately; for exact contact positions, see the mating face drawing of the selected model. When the device side uses female contacts, also verify the power supply direction and unmated protection.

Understand the structure.

Select mounting and contacts first, then take a closer look at the mating face, wiring back end, and catalog dimensional drawings. The appearance of the same structure can be shared; contact count and pin positions are verified independently.

PIN LAYOUT

Same housing — choose the right mating face.

Appearances may be similar; the mating face must be right. Contact count, contact size and pin/socket orientation are verified in one place.

The catalog face view is for identifying contact layout; where male/female and viewing direction are not marked, it does not replace the wiring diagram of the corresponding model. Click a pin count with a complete record to switch the configuration below.

Expand the original face view and check each item.

View by pin count, mating structure and contact grouping from the original documentation. Pin positions are not mirrored or rearranged; different original drawing variants are retained separately. Viewing direction, pin number functions and complete ordering numbers are confirmed per the final drawing.

Specifications for waterproof connectors and aviation plugs apply per the specific model. Configurations that look similar may differ in ratings, pin positions, and mounting structure.Full technical notes。

IP67 protection rating.IP67 indicates dust protection and short-term immersion protection under specified test conditions. The connector must be properly mated and locked, with seals intact, using cable of the specified outer diameter and completed installation sealing. Protection of unmated ports, the other end of the cable and the device cutout must be handled separately. Ratings and test conditions for specific models are subject to the product specification. Source and applicability Back to content
Rated current and voltage.Rated current is stated per individual contact or designated contact group of the selected configuration; rated voltage is stated per the corresponding insulation structure. Simultaneous energization of multiple contacts, conductor cross section, ambient temperature, and heat dissipation conditions affect temperature rise and allowable current capacity. Selection results are for initial screening only; final selection must be verified against the datasheet and temperature-rise validation under actual operating conditions. Source and applicability Back to content
Hybrid power and signal configuration."3+2" and similar notations indicate the number of contacts in two contact groups. Current, voltage and wiring specifications must be verified separately; the rated currents of the two groups cannot be added together as an overall system rating. Different pin counts and contact-face layouts do not thereby imply intermateability; the viewing direction of the contact face, keying, and male/female contacts must all be confirmed together. Source and applicability Back to content
Wire diameter and seal fit.Enter conductor cross section per contact in mm²; cable outer diameter refers to the jacket outer diameter in mm. The two are not interchangeable. Conductor capacity can be pre-screened against the catalog maximum, but the cable outer diameter must fall within the sealing fit range—do not judge solely by whether the product maximum exceeds the cable diameter. AWG follows the corresponding wire gauge in the catalog. Source and applicability Back to content
Mounting form and face view.Front-mount panel, rear-mount panel, flange, and in-line mating describe the mounting structure; male and female contacts describe the contact form—the two are selected separately. Face views should indicate both the viewing direction and the locating datum; do not infer mating compatibility from left-right mirroring. Panel thickness, cutout, and locking conditions follow the drawing of the corresponding part number. Source and applicability Back to content
Image and demonstration notes.Product images are rendered from 3D data provided by the company; lighting, backgrounds, water droplets, light effects and particles illustrate the application environment and cannot replace test results. Protected structures are shown in desensitized appearance illustrations; none may be used as a basis for manufacturing, measurement, wiring or mating. For engineering documentation, apply to LLT per project. Source and applicability Back to content
Conditions of use.Installation and maintenance should follow product specifications and equipment safety requirements. Connectors not explicitly rated for live mating should be operated only after power-off. Protection performance depends on seal condition, assembly method, cable fit, and the operating environment; custom designs require corresponding sample validation. Source and applicability Back to content
Dust protection boundary.The dust protection requirements of IP6X apply to the verified sealed state. End faces, sealing rings and locking areas should be kept clean to prevent sand and dust from being trapped and affecting mating and sealing. The dust rating does not mean the connector can be used in explosive dust atmospheres. Source and applicability Back to content
UV resistant."UV resistance of 1000 hours or more" is performance information provided by the company; its applicability should correspond to the material grade, color, product version and the corresponding test records. Accelerated aging duration cannot be directly converted into years of outdoor service life; UV light source, irradiance, temperature-humidity cycling and evaluation items follow the corresponding report. Source and applicability Back to content
Salt spray and corrosion resistance."Salt spray of 480 hours or more" is performance information provided by the company for a specific combination of materials and plating. Results apply only to the corresponding plating thickness, specimen condition, test conditions and acceptance criteria, and cannot be directly converted into service life in coastal environments. Appearance corrosion criteria and electrical performance criteria should be confirmed separately. Source and applicability Back to content
