Product Details

Right-Angle Configuration for Compact Power Enclosures	High-Thickness Gold Plating for Corrosion Resistance	35A High-Current Capacity with Insulation Support
Feature: Precision-molded Right Angle (90-degree) terminal orientation with a wide 5.84mm mating tab width.	Feature: Premium 30 micro-inch (0.76 um) Gold (Au) plating on the mating area over a pure copper base.	Feature: Engineered to support a 35A max current rating combined with an integrated wire insulation support barrel.
Advantage: Dramatically minimizes cable bending stress and reduces the depth profile needed within power distribution boxes.	Advantage: Eliminates fretting corrosion, prevents terminal oxidation, and guarantees ultra-low contact resistance over hundreds of mating cycles.	Advantage: Prevents excessive heat generation/temperature rise under heavy electrical load while eliminating wire fraying from movement.
Benefit: Allows engineers to optimize tight space layouts in industrial control cabinets without sacrificing high-power delivery.	Benefit: Ensures flawless signal and power continuity in harsh, humid, or chemically aggressive environments, cutting maintenance costs.	Benefit: Guarantees critical equipment safety and reliable connections in heavy vibration applications, avoiding intermittent power cuts.

Q1: What are the main applications for the TE Type XII 66740-6 contact?

A: Due to its massive 35A current rating and robust copper build, the 66740-6 is widely used in heavy-duty commercial applications, industrial power supply racks, power distribution systems, and modular connector assemblies requiring reliable bulk power.

Q2: What is the benefit of the 30 micro-inch gold plating on this contact?

A: The heavy 30 uin [0.76 um] gold plating ensures maximum protection against harsh environmental oxidation and wear from high mating cycles. It provides a highly stable, low-resistance connection, which prevents localized overheating under full 35-amp loads.

Q3: Does the 66740-6 require a specific crimping tool?

A: Yes. To achieve a secure, industrial-grade crimp that satisfies the wire insulation support feature on 16 AWG wires, you must use the appropriate TE Connectivity Type XII application hand tools or die sets. Proper crimping prevents mechanical wire pull-outs and electrical hot spots.
