circularbayonethigh-current

Product Summary
M28 2-pin waterproof circular connector with a bayonet locking mechanism, IP67 protection when correctly mated and assembled, and an 80 A current rating. Designed for energy storage and industrial power connections. Confirm cable sizing, operating conditions and the matching connector before ordering.

Product Overview

• 80 A High Current Capacity – Φ4.8 mm copper alloy contacts support the 80 A rating. Confirm rated voltage, conductor size and derating for your application; withstanding (test) voltage is not continuous operating voltage.
• Bayonet Locking Mechanism – Quick 90° twist connect/disconnect with audible locking feedback for vibration resistance and prevention of accidental disconnection.
• IP67 Waterproof & Dustproof – Fully sealed against water and dust when mated and assembled correctly; suitable for harsh outdoor and industrial environments.
• Wide Cable Compatibility – Supports Φ10.0 mm–Φ19.0 mm cable diameters for flexible installation.
• Global Certifications – ISO9001, CE, UL and RoHS.
