IF 1890 - TMC3 Cable Gland
Armored and non-armored compatibility is a core feature of the TMC3. This means you can stock a single gland for a wide range of MC cables, reducing SKU sprawl and simplifying procurement. In practice, technicians install it on both armored and non-armored runs, accelerating cabinet builds and field retrofits. The 1" NPT aluminum gland provides durable mounting and excellent corrosion resistance, simplifying installation and long-term maintenance. Aluminum construction supports lightweight handling without compromising strength in industrial environments. The armor (0.800"–1.120"), cable (0.850"–1.310"), and outer sheath (0.850"–1.310") ranges ensure a snug, compliant seal across common MC configurations, improving ingress protection and eliminating rework. IP66 and NEMA 4X ratings enable reliable operation in washdown, dust-prone, and outdoor locations, reducing protective enclosure requirements and enhancing uptime. Certification coverage including NEC/CEC IECEx and ATEX supports global deployments in regulated sectors such as oil, gas, and chemical processing.

FAQs
Yes. The TMC3-100-1 uses a 1" NPT thread and is qualified for both armored and non-armored MC cables within its specified armor (0.800"–1.120") and cable (0.850"–1.310") ranges. This reduces the need for multiple gland variants, streamlining procurement and on-site installs. Always verify enclosure clearance and thread engagement during mounting to maximize the seal integrity.
The gland carries NEC/CEC IECEx and ATEX certifications, with IP66 ingress protection and a NEMA 4X rating. These specifications support operation in hazardous locations, outdoor exposure, and washdown conditions. This combination helps maintain safety, uptime, and compliance across global installations without needing additional protective measures.
Yes. The TMC3 is certified for ATEX/IECEx, meeting requirements for hazardous/classified locations. It also offers IP66 and 4X protection, which are critical for chemical processing environments where dust, water jets, and corrosive exposure are common. Use in these settings reduces risk and compliance overhead while enabling long service life.
Key specs include aluminum construction for corrosion resistance, 1" NPT thread, armor range 0.800"–1.120", cable range 0.850"–1.310", and outer sheath range 0.850"–1.310". These factors influence enclosure fill, gland fit, and sealing efficiency. The combination supports compact panel designs and easier field routing for both armored and non-armored cables.
The TMC3’s dual compatibility (armored and non-armored) and robust aluminum construction reduce spare parts and SKU variety, cutting procurement and stocking costs. Its IP66/NEMA 4X protection minimizes enclosure maintenance and water/dust ingress concerns, contributing to higher uptime and lower maintenance expenses over the equipment’s lifecycle.
