Amphenol SurLok Plus Battery Connectors
High-current DC connectors rated up to 1500V for battery storage, solar, UPS, and electric vehicle applications. Touch-safe IP2X design — no exposed live parts. Available in plugs, sockets, and pre-assembled cables with four termination options.
Product Range
The SurLok Plus series comes in three sizes, each available as plugs (male), sockets (female), and pre-assembled cables. Orange denotes positive, black denotes negative — standard DC colour coding for safe polarity identification.

Product Types
🔋 Battery Plugs
Male connectors that attach to the cable. Available in orange (positive) and black (negative). Cable entry sizes from 16mm² to 120mm².
🔌 Battery Sockets
Female connectors that mount on the battery or bus bar. Four termination types: threaded bar (M), outer thread (LD), inner thread (LM), and crimp (H).
🔗 Pre-Assembled Cables
Connector already crimped and assembled on one end — just terminate the cable end. Available in orange (positive) and black (negative) with threaded bar, outer thread, and inner thread terminations.
Socket Termination Types
All sockets share the same external appearance — the difference is how the conductor connects internally. Choose the termination type that matches your installation.
⬤ Threaded Bar (M)
Stud passes straight through. Most common — ideal for bus bars and flat terminals.
⬤ Outer Thread (LD)
Stud inserts from outside. External threads for through-panel mounting.
⬤ Inner Thread (LM)
Stud screws in from inside. Flush mount for confined spaces.
⬤ Crimp (H)
Direct cable crimp — no stud required. Best for permanent assemblies.
Colour Coding
Orange — Positive (+)
Positive DC connections. Immediately visible for safety compliance checks.
Black — Negative (−)
Negative DC connections. Standard industrial colour for ground and return paths.
Applications
Compatibility
All plugs and sockets within the same series are compatible — any termination type socket mates with any plug of the same size and colour. Pre-assembled cables include the connector already attached.
| Series | Plugs | Sockets | Cables | Mates With |
|---|---|---|---|---|
| CN06 | 4 | 8 | 6 | All CN06 plugs ↔ all CN06 sockets |
| CN08 | 4 | 8 | 6 | All CN08 plugs ↔ all CN08 sockets |
