MIL-DTL-24643/8 LSMMOP Shipboard Cable

Mil-Spec Military part number MIL-DTL-24643/8 is comprised of one cable-type designation: LSMMOP. LSMMOP is available in a five-conductor version and can be categorized by the Standard Identification Code using either Method 1 or 3. 24643/8 cord uses thermoset insulation and has an outer cross-linked polyolefin jacket (XLPO). LSMMOP cables have multiple conductors and are heat and oil-resistant. LSMMOP has five conductors and is oil-resistant. MIL-DTL-24643 cable is non-watertight and offers flexing service. The cords are constructed with the required number of cables which are consecutively arranged around a central tie cord. This cable is suitable for use in one or two connected compartments but may not be used to penetrate a bulkhead or watertight deck.

What does the cable designation LSMMOP mean?

In the cable designation for LSMMOP, the letters LS refer to low smoke and halogen-free cable. The third letter, “M” stands for multiple conductors. O refers to a cable that is heat and oil-resistant, and P refers to portable cords.

M24643/8 Construction:

• Conductors: Either stranded coated or uncoated copper conductor
• Insulation: Either Ethylene Propylene Rubber (EPR) or Cross-Linked Polyethylene (XLPE)
• Jacket: Low-Smoke, Halogen-Free XLPO is highly durable and operates well in high heat

Features and Benefits of M24643/8 Cords

• Non-watertight
• Thermoset insulation is ideal for settings where durability and stiffness are essential
• LSZH jacket is fire resistant and emits low smoke, which is ideal for shipboard settings which often have restricted ventilation
• Heat and oil-resistant feature reduces maintenance and cable replacement needs
• Portable cords with flexing service permit use in applications where repeated use may require flexing without damaging the cord’s internal conductors
