Pollak 12-811 ISO 7-Way Connector Plug – Heavy-Duty Die-Cast with Steel Cable Guard

Professional-Grade Power for Supplemental Trailer Functions

The Pollak 12-811 7-Pole ISO Plug is engineered for specialized auxiliary power requirements in the commercial trucking and towing industries. Unlike standard SAE J560 plugs, this connector adheres to the ISO 3732 (Type S) standard, commonly used to provide supplemental power for specialized equipment, interior trailer lighting, and battery charging circuits.

Maximum Protection & Durability Designed to withstand the harshest environments, the 12-811 features a rugged zinc die-cast housing that offers superior impact resistance compared to plastic alternatives. The integrated heavy-duty steel spring cable guard prevents wire kinking and strain at the connection point, significantly extending the life of your trailer cable.

Secure and Reliable Connectivity Inside, the plug utilizes solid brass terminals for maximum electrical conductivity and minimum voltage drop. The polarized ground terminal ensures correct alignment every time, preventing accidental cross-circuiting.

Key Features:

• ISO 3732 Compliant: Specifically designed for "Type S" (Supplementary) 7-way applications.

• Die-Cast Zinc Construction: Provides high-strength durability and corrosion resistance.

• High-Strength Cable Guard: Features a close-coiled zinc-plated spring to protect against wire fatigue.

• Polarized Design: Ensures proper mating and prevents the plug from being inserted into standard J560 sockets incorrectly.

• Solid Brass Pins: Machined from solid bar stock for consistent power delivery and reduced heat.

Common Applications:

• Supplemental trailer power (Type S)

• Interior trailer lighting and accessory circuits

• Battery charging and auxiliary 12V-24V feeds

• Specialized commercial vehicle fleets
