Eaton Specification Sheet - TMCXM20 1
Feature: Explosion-proof, armor-friendly Terminator II design. Benefit: Provides robust protection in hazardous locations, reducing risk of ignition and simplifying regulatory compliance for plant-wide wiring schemes. Application: Ideal for metal-clad, armoured barrier and tray cables in chemical, refining, and mining environments. Feature → Business Impact → Application: Streamlined installation with M20 metric thread and aluminum body lowers torque requirements and weight, accelerating field terminations on large motor feeds and control panels. Application: Panel builders and service teams in water treatment and processing plants benefit from faster commissioning and safer assemblies. Long-tail keywords integrated: armoured cable glands for hazardous locations, NEC/CEC compliant gland, explosion-proof cable gland, TECK armoured compatibility. Feature: Cable sealing range of 12.4-22.8 mm and sealing option 1 (S) ensures wide cable accommodation, reducing the need for multiple gland sizes. Benefit: Minimizes inventory, lowers procurement costs, and improves changeout speed during maintenance windows. Application: Retrofit projects and new installations in hazardous zones where cable diameters vary. Feature: Material is aluminum with corrosion resistance. Benefit: Lighter weight, easier handling, and improved thermal performance for compact enclosures. Application: Outdoor and damp environments where corrosion resistance matters. Feature: Barrier type is TSC Compound with armoured gland construction. Benefit: Enhanced sealing integrity against dust and moisture ingress, protecting sensitive electronics. Application: Marine console, offshore platforms, and mining equipment where rugged sealing is critical. Feature: NEMA Rating 4X, 6P and NEC hazardous location ratings. Benefit: Clear compliance signals for safety and insurance requirements, reducing inspection cycles. Application: Any installation requiring formal certification for hazardous zones. These combined advantages support installation efficiency, verify compliance, and extend asset life across critical automation projects.

FAQs
For installation, ensure the M20 thread matches the panel or enclosure gland bore, use the aluminum body for corrosion resistance, and secure with appropriate locking fittings. Verify cable diameter falls within the 12.4-22.8 mm range, and confirm armoured cable compatibility (interlocked or welded corrugated armour) to maintain the gland’s explosion-proof integrity in hazardous locations.
Yes. The gland is designed for NEC/CEC compliance in Hazardous/Classified Locations, with a NEMA rating of 4X and 6P. It provides explosion-proof protection suitable for Class I, II, and III environments, helping streamline regulatory approvals and installation inspections in industrial facilities.
The gland supports armored barrier and metal-clad cables, including TECK armour and tray cable configurations. It is rated for a cable range of 12.4-22.8 mm with a sealing option of 1 (S), and its armoured design is compatible with interlocked or continuously welded corrugated armour for robust field installs.
The M20 metric thread standardizes mounting on a wide range of enclosures, reducing the need for adapters. The aluminum body keeps weight manageable while delivering corrosion resistance and adequate mechanical strength for hazardous-area installations, contributing to quicker terminations and durable performance under demanding conditions.
Expect reduced downtime due to faster installations and fewer seal failures in hazardous zones. The gland’s robust sealing, compatibility with armoured cables, and NEC/CEC compliance lower inspection and maintenance costs, while the NEMA 4X rating protects against moisture and corrosion, extending service life for critical automation assets.
