Product Overview

  • 120A Power + 10A Signal – Hybrid connector with 120A power pins (6.0mm) and 10A multi-signal pins (1.5mm gold-plated).

  • Quick Lock Mechanism – Tool-free connection with audible feedback, anti-vibration for secure locking.

  • IP67 Waterproof Protection – IP67-rated interface; confirm the specified mating, cable-gland and installation conditions for your application.

  • BMS and Industrial Control – Designed for battery management systems, hybrid signal transmission, and industrial controls.

  • Global Certifications – Request the documentation applicable to this exact model and configuration; approval scope must be checked before use in a regulated program.

Confirm the 2+5 Pin Configuration Before Ordering

The product's 120A power and 10A signal ratings apply to different contact groups; do not treat all seven contacts as 120A circuits. The series specification table also lists other MJ32 variants. Use the 2+5 pin drawing and the selected mating pair when approving your wiring design.

Check continuous and peak load, operating voltage for each circuit, ambient temperature, conductor size, cable outside diameter, pin assignments and panel clearance. Validate temperature rise and sealing on the assembled cable under your application's conditions.

Request a Drawing and Sample Review

Send JNICON your BMS wiring diagram, current and voltage requirements, cable details, installation environment and planned quantity. Ask for the mating-pair drawing, applicable documentation and sample plan through our technical inquiry and quotation page. For validation planning, review our high-current connector overheating test checklist.

Product Advantages

High-Reliability Waterproof & Dustproof Protection

High-Reliability Waterproof & Dustproof Protection

All products in our series feature high-reliability waterproof and dustproof protection. IP67 certified models withstand temporary immersion up to 1 meter for 30 minutes. IP68 certified models are designed for prolonged submersion in demanding environments (specific depth and duration refer to product datasheet). For applications requiring frequent high-pressure high-temperature washdown — such as food processing, agricultural machinery, and heavy equipment — IP69K protection is available as a customizable option.

Note: IP69K is an optional custom feature and is not standard across all models.


Wide Operating Temperature Range

Wide Operating Temperature Range

Our connectors operate reliably across a broad temperature range from -40°C to +105°C (with certain energy storage series reaching up to +125°C). This ensures stable performance in extreme climates — from freezing winters to scorching summers — making them suitable for desert, snowy, high-altitude, and other harsh environmental conditions.


High-Strength Flame-Retardant Housing

High-Strength Flame-Retardant Housing

The housing is constructed from high-performance engineering plastic with UL94 V-0 flame-retardant certification, ensuring self-extinguishing properties in case of fire. The structural design also provides impact resistance, protecting internal precision terminals from accidental collisions and mechanical shocks in industrial environments.

High Mating Cycle Durability

High Mating Cycle Durability

Our connectors are rated for 500+ mating cycles, validated through rigorous plug-and-unplug testing. In frequent connection and disconnection scenarios, they maintain stable contact performance and consistent electrical reliability — effectively reducing maintenance frequency and replacement costs over the product lifecycle.
