Eaton Specification Sheet - TMCXM20 1 L
Cable range compatibility drives efficiency: the 12.4-22.8 mm cable range and 1 (S) sealing range align with common armored, barrier, metal-clad, TECK, and tray cables, reducing the need for additional glands and inventory. Aluminum construction delivers a favorable strength-to-weight ratio, improving handling and installation speed while resisting corrosion in harsh environments—key for outdoor or washdown-heavy facilities. The Liquid Compound barrier provides a robust ingress seal, lowering maintenance costs and downtime by safeguarding against moisture and dust ingress in hazardous locations. This gland supports interlocked or welded corrugated armour and armored barriers, enabling streamlined retrofits and consistent performance across TMCX II and related gland families. The M20 thread size offers straightforward mounting on standard enclosures, simplifying procurement and field installation. Compliance with NEC/CEC hazardous-location standards and NEMA 4X protection delivers regulatory peace of mind, reducing audit risk and procurement complexity for industrial projects.

FAQs
To install the TMCXM20 1 L in armored cable systems, ensure the enclosure entrance matches the M20 thread and the cable range is within 12.4-22.8 mm. Use the Liquid Compound barrier to seal the gland against moisture and dust, and connect to armored cables compatible with interlocked or welded corrugated armour, TECK armour, or tray cables. Follow installation sheets such as IF 1647B for proper torque and sealing.
Explosion-proof protection is provided by Terminator II design and NEC/CEC ratings, including Class I, Division 1; Class II, Division 1; and Class III. The aluminum housing, armored barrier, and Liquid Compound gasket deliver a gas-tight seal and enclosure integrity in hazardous locations. The gland also carries a NEMA 4X rating for rugged outdoor use and frequent washdowns.
Yes, the TMCXM20 1 L is suitable for tray cables and armored barrier systems. It accepts armoured barrier, metal-clad with interlocked or welded corrugated armour, TECK armour, and tray cable configurations. Its M20 thread allows mounting on standard enclosures, while the 12.4-22.8 mm cable range covers common field cables, reducing the need for adapters or different glands.
Certifications supporting use in regulated facilities include NEC/CEC standards for hazardous locations and the NEC hazardous ratings, including Class I, Division 1, Class II, Division 1, and Class III. The gland also carries a NEMA 4X rating and Canadian safety certifications cited in UL reports. These approvals streamline project approvals, compliance audits, and cross-border procurement.
From a maintenance and ROI perspective, the TMCXM20 1 L reduces ingress-related failures with its Liquid Compound barrier and robust aluminum housing, lowering service calls. Its wide cable range and armored compatibility minimize part variation, speeding installations. Long service life in harsh environments translates to lower lifecycle costs and faster project payback.
