Battery Connector, Single Pole Power Connector - SI Series

Single Pole Power Connector

 

The ​​SI series power connector​​ is a high-performance, versatile solution engineered for demanding wire-to-wire and wire-to-board applications across industries. Designed to accommodate wire sizes from 12 AWG to robust 3/0 AWG, it supports both low-voltage signaling and high-current power transmission up to hundreds of amps, ensuring adaptability for diverse electrical needs. Featuring interchangeable contact types—such as crimped, screw-terminated, or quick-disconnect options—the SI series enables rapid, secure connections while minimizing resistance and heat buildup. Its rugged construction and corrosion-resistant materials make it ideal for harsh environments, from electric vehicle powertrains and industrial UPS systems to precision medical devices and heavy-duty power tools. With a focus on reliability, scalability, and fast installation, this connector series streamlines complex power distribution challenges while meeting stringent safety and durability standards in global markets.

 

 

 

Features

 

1. Versatile Wire Compatibility
   • Supports wire sizes from ​​20 AWG (thin) to 4/0 AWG (0000, very thick)​​, accommodating both low- and high-current applications.
   • Ideal for scenarios requiring flexibility, such as industrial machinery or electric vehicles (EVs).
2. ​​Connection Types
   • ​​Wire-to-Wire:​​ Joins cables in systems like UPS or battery arrays.
   • ​​Wire-to-Board:​​ Connects wires to PCBs in electronics or medical devices.
3. ​​Contact Variants
   • Contacts may vary in ​​material​​ (e.g., brass, gold-plated for corrosion resistance) and ​​design​​ (e.g., blade, screw terminals) to suit different current loads and environments.
   • Likely optimized for high-current performance (e.g., 4/0 AWG handles ~300+ amps).
4. ​​Fast Installation
   • Designed for quick assembly, possibly using ​​tool-less​​ mechanisms (e.g., push-in) or ​​crimping/screw terminals​​ for secure, low-resistance connections.

Applications

 

​1. Electric Vehicles & Mobility​​

 

Anderson connectors are pivotal in ​​EVs, golf carts, and e-bikes​​, handling high-current connections between batteries, motors, and controllers. Their SB® series (e.g., SB50, SB175) supports 50–350A loads, ensuring efficient power transfer with minimal resistance. Quick-disconnect features enable safe battery swaps or emergency shutdowns, while color-coded housings prevent mismating. These connectors withstand vibration, moisture (IP67 options), and temperature swings, making them ideal for off-road EVs, forklifts, and hybrid systems. They’re also used in charging stations for secure, high-speed energy delivery, complying with automotive standards like SAE J1772 and UL 2251.

 

​​2. Renewable Energy Systems​​

 

In ​​solar, wind, and battery storage systems​​, Anderson connectors link panels, inverters, and battery banks with reliability in harsh environments. Their Power-Pole® series (15–350A) ensures low-voltage drop for solar arrays, while IP65-rated models resist dust and rain. Widely adopted in off-grid setups, they simplify maintenance and expansion of renewable systems. For lithium-ion or lead-acid batteries, their polarized designs prevent reverse polarity, and flame-retardant housings meet UL 1977 standards. They’re also critical in portable solar generators and microgrids, offering field-serviceable connections that endure UV exposure and thermal cycling.

 

​​3. Industrial Machinery & Material Handling​​

 

Anderson connectors power ​​forklifts, AGVs (Automated Guided Vehicles), and heavy machinery​​, where 120–400A connections are routine. Their robust contacts handle inrush currents from motors and winches, while stainless steel latches survive industrial abrasion. In warehouses, they connect battery-powered pallet jacks and robotic systems, enabling fast battery replacement to minimize downtime. High-cycle models (10,000+ mating cycles) are used in assembly lines, and their touch-safe designs protect workers during live operations. They also integrate with PLCs and sensors in automated factories, meeting ISO 13849 safety requirements for machinery.

 

​​4. Telecommunications & Backup Power​​

 

For ​​UPS systems, telecom towers, and data centers​​, Anderson connectors provide fail-safe links between backup batteries and critical infrastructure. Their 30–350A models ensure uninterrupted power during outages, with low-resistance contacts that reduce heat buildup in high-density racks. In 5G networks, they connect lithium batteries to remote radio units, surviving temperature extremes (-40°C to +105°C). They’re also used in portable generators and emergency response equipment, offering rapid deployment and compatibility with global voltage standards. UL and CE certifications make them a go-to for mission-critical power redundancy.

 

​​5. Marine & Outdoor Equipment​​

 

Anderson’s waterproof (IP68) connectors are essential in ​​boats, RVs, and off-grid lighting​​, resisting saltwater corrosion and humidity. They power trolling motors, winches, and solar panels on marine vessels, while 175A+ models handle windlass systems. In construction and agriculture, they connect heavy-duty tools, LED light bars, and auxiliary batteries on trucks/ATVs. Their rugged housings endure mud, dust, and mechanical stress, making them ideal for military, mining, and disaster-relief equipment.
