Lenco 5066 LC-40 Double Oval-point Screw Cable Connector

Product Description

The LENCO 5066 is an LC-40 double oval-point screw cable connector designed for heavy-duty welding cable connections. The cam-action male half pulls the two connector halves firmly together, creating a secure, low-resistance electrical junction. Connector covers are molded from a special heat- and cold-resistant material with no metal liner, eliminating the risk of rust and corrosion over time. Metal parts are precision machined for consistent fit and long service life. This connector is handled by welding professionals and electricians working with high-amperage welding equipment in demanding shop, field, and industrial environments.

The LENCO 5066 LC-40 connector is suited for applications requiring a reliable, field-disconnectable cable joint on welding leads. The dual oval-point screw design secures the cable conductor inside the connector body without the need for soldering. The color-coded red and black configuration supports quick polarity identification when connecting electrode and work leads. This connector type is commonly installed on welding machines, electrode holders, and ground clamp leads in both shop and portable field setups.

Key Features

• Cam-action design pulls male and female halves together for a tight, secure connection
• Double oval-point screws lock cable conductor firmly in place without soldering
• Heat- and cold-resistant molded covers for durability across wide temperature ranges
• No metal liner in connector covers eliminates rust and corrosion risk
• Precision-machined metal parts for consistent fit and repeatable engagement
• Red and black color coding supports fast polarity identification in the field

Compatibility

Designed as an OEM-style replacement or serviceable connector for LC-40 series welding cable connector applications on standard welding leads.

Installation Notes

Installation is performed by welding technicians or electricians familiar with welding lead assembly. Disconnect and de-energize the welding machine before working on cable connectors. Insert the stripped cable conductor into the connector body and tighten the oval-point screws to secure the conductor before mating the connector halves. Follow applicable NFPA 70 (NEC) guidelines for welding equipment wiring and conductor sizing.
