Ultra grip locking design provides a secure engagement that resists vibration and accidental pullouts, reducing unplanned downtime in motors, drives, and equipment housings. In real-world panels, this means fewer reseats after maintenance and longer service intervals, improving overall equipment effectiveness and uptime. Flat cable compatibility with back wiring streamlines terminations, enabling neat, reliable harnesses while cutting installation time and miswiring risks in tight control cabinets and machine enclosures. Four-pole five-wire configuration delivering 120/208V at 20A aligns with common industrial power distribution, supporting motor starters, drives, and feeders while enabling plug-and-play integration with existing L21-20 systems. The nylon housing and brass contacts deliver robust durability with corrosion resistance, allowing reliable operation from -40 to 60 C in harsh plants and outdoor-rated environments. RoHS compliance and NOM cULus listing reduce regulatory risk for global manufacturing, while back-wiring and flat-cable compatibility simplify field upgrades and panel retrofits. This device is designed for industrial duty, delivering predictable performance and lower maintenance costs through a proven locking mechanism and high-quality materials.

FAQs
The AHL2120CF uses back wiring with flat cable and is designed to accept up to five conductors, including a ground. For installation, power off the panel, mount the connector, strip and insert wires within the allowable size (flat cable up to #10 AWG, overall wire size #14-8 AWG), connect to the appropriate terminals per the NEMA L21-20 configuration, and secure with the locking mechanism. Verify tightness and continuity before re-energizing.
The connector is rated for 20A and operates at 120/208V with a four-pole, five-wire configuration (NEMA L21-20). This supports three-phase power delivery and common industrial control circuits. It is compatible with industrial motors, drives, and distribution panels that use L21-20 wiring schemes, enabling reliable, standardized connections in control rooms and equipment bays.
Yes. The AHL2120CF is designed for industrial duty with an extra heavy-duty specification grade. Its nylon body and brass contacts provide rugged durability and corrosion resistance, while the -40 to 60 C operating temperature range accommodates extreme facility conditions. The locking mechanism reduces vibration-induced disconnections, making it well suited for motor drives, feeders, and control panels exposed to industrial vibrations.
The AHL2120CF is RoHS compliant and NOM cULus Listed, ensuring regulatory compliance for hazardous substances and safety certifications across multiple markets. This helps mitigate regulatory risk during global deployments and supports confidence in procurement for healthcare, manufacturing, and automotive-adjacent facilities that require proven compliance.
The ultra grip locking design minimizes loosening from vibration, reducing reseating events and maintenance cycles. This translates to lower downtime, fewer spare parts, and extended service intervals. When combined with robust nylon housing and long-lasting brass contacts, you get predictable performance over the product lifecycle, delivering a favorable total cost of ownership for industrial automation projects.
