Panduit CESU2-E10 Cable Entry System, Un-Terminated

Overview

The Panduit CESU2-E10 is an un-terminated cable entry system designed for controlled and industrial enclosures where maintaining environmental sealing around cable penetrations is non-negotiable. Rated IP65 and NEMA 1/12, it stops dust infiltration and low-pressure water jets from compromising enclosure integrity — a practical necessity in panel rooms, junction boxes, and equipment cabinets exposed to washdown or industrial particulate. The polyamide 6.6 body and TPU/EPDM seals provide a durable, chemical-resistant assembly that holds up across a wide service temperature range without degrading the seal quality that earns the protection rating.

At 2.32 in wide × 5.79 in tall × 0.59 in deep and weighing under 0.2 lbs, the CESU2-E10 (often searched as CESU2 E10) installs cleanly into thin-wall panels without bulking up an enclosure door or side knockout. The un-terminated configuration gives installers the flexibility to dress and terminate cables to their own spec on-site rather than working around a factory-crimped end.

Key Features

• IP65 / NEMA 1 & 12 Protection: Fully dust-tight and resistant to directed water jets — deploy this where cabinet doors face occasional spray or heavy airborne particulate without worrying about seal degradation over time.
• Polyamide 6.6 Housing: Stronger and more dimensionally stable under heat than standard nylon variants; won't warp or loosen grip at the upper end of its rated temperature range, keeping the seal intact.
• TPU/EPDM Seal Material: TPU handles abrasion and oil exposure; EPDM resists UV and ozone — together they maintain compression set performance across repeated thermal cycles, not just at commissioning.
• -22°F to 158°F Operating Range: Covers unheated outdoor enclosures in cold climates and sun-baked rooftop panels in summer — a single SKU handles most North American deployment environments without substitution.
• 0.06–0.08 in Panel Thickness Compatibility: Fits standard thin-gauge steel and aluminum panel knockouts common in commercial electrical enclosures — no adapter plate or custom cutout required in most installations.
• cURus Listed: Carries both US and Canadian safety recognition, which matters when the AHJ is reviewing the panel build on a commercial or light-industrial project.
• HB Flammability Rating: Meets the baseline self-extinguishing requirement for enclosure components in commercial electrical assemblies — code-compliant for UL-listed panel builds.
• Compact Footprint (2.32 × 5.79 × 0.59 in, 0.198 lbs): Light enough that a populated enclosure door doesn't pick up meaningful weight; shallow depth keeps it clear of internal wiring runs and DIN rail components.

Integration & Compatibility

The CESU2-E10 is suited for use in enclosure cable management builds alongside other Panduit wiring and enclosure products. It integrates into standard panel knockout configurations used across network infrastructure cabinets, security system enclosures, and industrial control panels. For projects specifying full cable management systems, pair with Panduit's conduit fittings and cable tie mounts for a unified installation approach. Review your power enclosure planning requirements to confirm panel thickness falls within the 0.06–0.08 in rated range before ordering.

Frequently Asked Questions

Q: What panel thickness is compatible with the CESU2-E10?

A: The CESU2-E10 is rated for panel thickness of 0.06 to 0.08 inches, which covers standard thin-gauge steel and aluminum enclosure panels used in most commercial and light-industrial applications.

Q: What is the IP and NEMA protection rating?

A: The CESU2-E10 carries an IP65 rating (fully dust-tight, protected against directed water jets) and meets NEMA 1 and NEMA 12 standards, making it suitable for indoor industrial environments with airborne contaminants and occasional liquid exposure.

Q: What temperature range does the CESU2-E10 support?

A: It is rated for -22°F to 158°F (-30°C to 70°C), covering unheated cold-climate enclosures through sun-exposed rooftop or outdoor-rated cabinet installations.

Q: What certifications does the CESU2-E10 carry?

A: The CESU2-E10 is cURus listed, providing both US and Canadian safety recognition — relevant for commercial panel builds subject to AHJ review.

Q: What materials are used in the seal and housing?

A: The housing is polyamide 6.6 (a heat-stable, dimensionally rigid nylon variant) and the seals are TPU/EPDM, which maintain compression performance through thermal cycling and resist ozone, UV, and oil exposure.

Q: Is the CESU2-E10 terminated or un-terminated?

A: The CESU2-E10 is un-terminated, giving installers full flexibility to dress and terminate cables to project-specific requirements on-site.

The CESU2-E10 is the component that gets overlooked until an enclosure fails an IP rating test on-site — at which point everyone wishes they had specified it from the start. The TPU/EPDM dual-material seal is the spec worth paying attention to here: TPU handles the mechanical abuse of cable movement and oil vapor in industrial bays, while EPDM maintains its compression set through the thermal cycles that cause single-material seals to gap over time. That combination is why this entry system holds IP65 across its full -22°F to 158°F rated range rather than just at room temperature.

Technical Highlights:

• IP65 / NEMA 12 Dual Rating: Dust-tight plus directed-water resistance — one part covers both the cleanliness standards for electrical rooms (NEMA 12) and the wash-exposure environments common in food processing and light manufacturing.
• Polyamide 6.6 Body: Higher heat deflection temperature than standard PA6; the housing won't deform under sustained heat near the 158°F ceiling, which matters in poorly ventilated utility cabinets in summer.
• 0.06–0.08 in Panel Compatibility: Designed for standard commercial enclosure gauges — no custom fabrication or adapter plates needed on typical steel or aluminum panels.

Deployment Considerations:

• Confirm panel knockout dimensions match the CESU2-E10 footprint (2.32 in × 5.79 in) before ordering — the shallow 0.59 in depth clears most internal DIN rail and terminal block layouts, but measure clearance on tight assemblies.
• The un-terminated configuration means cable termination is entirely field-executed — factor that into installation labor estimates on high-density panel builds where pre-terminated alternatives may reduce on-site time.

This is the right call for commercial security and industrial control enclosures where the AHJ will review cURus compliance and the installation environment demands a seal that survives thermal cycling, not just the initial commissioning inspection.
