Introduction
In modern factory automation, robotics, sensor systems and industrial IoT, stable, waterproof and easy-to-install wiring components determine the long-term stability of your production line. At KWISMA, our full range of Connectors and Splitters delivers a one-stop connection solution covering M8, M12, 7/8, Y/T-type splitters, multi-port IO distribution boxes and pre-molded cables, perfectly solving complex on-site wiring pain points for engineers worldwide.
Industrial sites face harsh challenges: dust, splashing water, vibration, oil stains and electromagnetic interference. Ordinary wiring terminals easily suffer from loose contact, short circuit and signal loss. Our IP67-rated circular connectors and modular splitters are engineered to withstand extreme working conditions, cutting wiring costs, shortening installation time and lowering equipment failure rates.

Solenoid valve connectors for pneumatic control systems
Waterproof cable glands, heavy-duty rectangular connectors
Pushbutton junction boxes and robotic tubing kits
Core Advantages of KWISMA Connectors & Splitters
Industry-Grade Waterproof & Durability
All circular connectors adopt double-layer silicone sealing and metal threaded locking, reaching IP67 dustproof & waterproof. Zinc alloy metal housings pass 72h neutral salt spray test, resisting corrosion in workshop, coastal and chemical environments.
Fast On-Site Installation, Low Labor Cost
Field-assemble plugs need no special crimp tools; splitters and distribution boxes support plug-and-play sensor access. Compared with traditional terminal wiring, installation efficiency improves over 3 times, greatly reducing project construction cycle.
Stable Signal & Power Transmission
Contact pins use gold-plated phosphor bronze with ultra-low contact resistance. Shielded models effectively block motor and frequency converter electromagnetic interference, avoiding signal loss or equipment misoperation.
Full Modular Customization Support
Customizable pin count, cable length, wire gauge, straight/elbow shape, single/double-ended cables. OEM service for housing logo and packaging to match brand project standards.
Wide Application Compatibility
Suitable for automotive production lines, industrial robots, packaging equipment, logistics conveying, intelligent warehousing, environmental monitoring, new energy equipment and factory digital transformation projects.
Real-World Application Case
An automotive assembly plant previously adopted discrete wiring for hundreds of proximity sensors, leading to messy cables, frequent maintenance and high downtime. After switching to KWISMA M12 12-port splitters + 7/8 main power connectors:
Total cable consumption reduced by 58%
On-site wiring time cut from 7 working days to 2 days
Sensor signal failure rate dropped from 12% to less than 0.5% per year
LED indicator splitters enable quick troubleshooting without dismantling equipment
How to Select the Right Connector & Splitter
Confirm space size: Compact equipment → M8; General sensor IO → M12; Power transmission → 7/8
Signal type: Low-voltage sensor signal (unshielded); High-speed bus near motors (shielded metal type)
Wiring layout: Few sensors use Y/T splitters; Mass sensor deployment choose multi-port distribution boxes
Environment: Workshop with water/oil must select IP67 metal locking models
Conclusion
As factory automation upgrades, reliable connection components become the invisible foundation of intelligent production. KWISMA’s full series connectors and splitters integrate miniaturization, modularization and high protection, solving all industrial wiring pain points with standardized, cost-effective products.

M8 Connectors & Cables
M8 miniature circular connectors are the ideal choice for compact sensors, micro actuators and narrow-space equipment.
Field-wireable plugs & flange mount connectors, 3/4 pin options
Shielded versions available for low-interference signal transmission
Pre-cast single/double-ended cables with customizable lengths
Small size, light weight, IP67 waterproof, ideal for precision automated equipment
M12 Connectors & Splitters (Core Series)
M12 is the most widely adopted industrial circular connector for sensor/actuator IO systems, and our portfolio covers all mainstream demands:
Straight/angled male/female plugs, flange panel connectors
Y-type / T-type branch splitters to realize one-to-two signal distribution
Multi-port IO distribution boxes: 4-port, 8-port, 12-port single/dual channel
Built-in LED status indicators for real-time fault diagnosis
Metal shielded housing, excellent EMC performance for high-speed bus signals
7/8 Connectors & Cables
Designed for industrial power supply and heavy-duty signal transmission, widely used in fieldbus and machine power loops:
Flange connectors, pre-molded cable assemblies, T-shaped on-site splitters
Large current carrying capacity, robust metal locking thread
Integrated silicone sealing rings to achieve stable IP67 protection
Perfect for packaging machinery, conveying lines and large robot power wiring
Multi-way Splitters & IO Junction Boxes
Traditional wiring requires running individual sensor cables all the way back to control cabinets, wasting cable and labor. Our M12 multi-port distributors change this logic:
Centralize dozens of sensor signals into one main cable to the cabinet
Reduce cable usage by 60% and simplify on-site cable management
Elastic terminal design, no soldering required for fast wiring
Fully enclosed anti-dust housing, anti-vibration structure for long-term factory operation
