Connector selection guide
How to Select an LP Series Connector
Choosing the right LP Series industrial waterproof connector starts with four practical requirements: electrical load, cable dimensions, mounting style and operating environment.
-
Electrical Load & Pole Count
Confirm the maximum voltage, current and number of power, signal, control and grounding conductors. Allow an appropriate safety margin for the application.
-
Cable Size
Match both conductor cross-section and cable outer diameter. Correct cable fit is essential for secure assembly and reliable environmental sealing.
-
Mounting Style
Use inline types for cable-to-cable wiring. Choose panel mount waterproof connectors or flange types for fixed equipment interfaces.
-
Environment & OEM Needs
Consider moisture, dust, vibration, temperature and maintenance frequency, plus any custom cable length, color, logo or assembly requirements.

Installation formats
Cable Mount vs. Panel Mount LP Series Connector Options
LP Series industrial waterproof connectors are available in cable-mounted and panel-mounted configurations. Choose the format according to where the connection is installed, how it moves and how technicians need to access it.
Flexible connection
Cable Mount (Inline)
Cable mount connectors attach directly to the cable and are commonly used for cable-to-cable connections, modular wiring and replaceable equipment leads.
- Cable extensions and modular wiring
- Flexible routing and field replacement
- Selected by cable OD, wire size and strain relief
Fixed interface
Panel Mount (Fixed)
Panel mount waterproof connectors create a fixed connection point on an equipment housing, control box or power unit for stable internal-to-external wiring.
- Equipment housings and control panels
- Flange, fixed-interface and cap options
- Selected by cutout, thickness and rear clearance
Mounting Format Comparison
Quick selection reference| Selection Factor | Cable Mount / Inline | Panel Mount / Fixed |
|---|---|---|
| Installation | Attached directly to the cable | Fixed to an equipment panel |
| Best For | Cable extensions and modular wiring | Housings, control boxes and power units |
| Movement | Moves with the cable | Remains fixed on the equipment |
| Key Dimensions | Cable OD and conductor size | Panel cutout, thickness and rear clearance |
| Maintenance | Replaceable cable section | Stable equipment service interface |
| Protection Check | Cable entry and mated sealing | Mated sealing and optional protective cap |
Selection tip: Choose cable mount industrial waterproof connectors for flexible cable-to-cable wiring. Choose panel mount types for a permanent, serviceable equipment interface. In both cases, confirm pole count, current rating, cable range and IP protection for the complete assembled connection.
Installation guidance
LP Series Connector Mating, Locking and Installation Guide
Correct assembly supports the electrical performance, mechanical security and environmental sealing of LP Series industrial waterproof connectors. Follow the applicable model datasheet before placing the connection into service.
Disconnect and isolate power before installing, mating, inspecting or disconnecting a connector. Installation should be completed by appropriately qualified personnel.
-
Prepare and Inspect
Confirm that the connector, contacts, seals and cable range match the selected model.
-
Align and Mate
Match the alignment keys and insert the connector straight without forcing or twisting the contacts.
-
Lock and Seal
Fully engage the locking mechanism and secure the cable gland according to the applicable datasheet.
-
Inspect and Test
Confirm complete engagement, inspect the seals and perform the required electrical tests before energizing.
Important: The stated IP rating depends on the correct cable range, complete assembly and fully mated condition. Unmated protection may require a sealing cap. Always follow the applicable datasheet for these industrial waterproof connectors.

Performance verification
IP68 Sealing and Mechanical Performance Testing
The performance of LP Series industrial waterproof connectors depends on the selected model, cable range, assembly method and fully mated condition. Testing should use clearly defined project conditions.
IP68 Sealing
Check water and dust ingress using the applicable method, defined conditions and correctly assembled samples.
Locking and Retention
Verify that the locking structure remains engaged during handling, cable movement and the required retention load.
Vibration Stability
Evaluate mechanical engagement and electrical continuity under the vibration conditions required by the application.
Cable Entry
Confirm that the cable gland matches the cable diameter and provides suitable sealing and strain relief.
Important: IP68 performance is not automatic in every installation. Confirm the test method, duration, sample condition and whether protection applies while mated or capped. Panel mount waterproof connectors should also be checked for panel sealing and mounting stability.
