SHR-95-BLK Cable Accessories for Electronic Projects - Parts & Picks at Communica

Overview & Typical Uses

In hobbyist and professional builds, SHR-95-BLK items are chosen for runs where a specific diameter or shrink ratio is needed. Typical applications include insulating solder joints, bundling multi-core cables, reinforcing cable entry points in enclosures, and providing a neat, black finish that matches consumer and industrial gear. For South African makers and technicians, these parts suit Arduino/Raspberry Pi projects, motor controllers, sensor harnesses, and small appliance repairs.

Common product forms

• Heat-shrink tubing (single-wall and adhesive-lined)
• Braided cable sleeving and expandable mesh
• Moulded strain relief boots and grommets
• Pre-cut sleeves, adhesive wraps and heat-shrink splice kits

Standards, Materials & Specification Callouts

Key specs to check when selecting SHR-95-BLK parts include nominal inner diameter, shrink ratio (e.g., 2:1, 3:1), operating temperature range, material type (polyolefin, PVC, PTFE), and whether adhesive lining (dual-wall) is present for moisture sealing. For sleeving, note expansion ratio and abrasion resistance. Strain reliefs are rated by cable diameter range and tensile support. See our SHR-95-BLK specifications and features for a detailed breakdown.

Selection Criteria & Compatibility

When choosing SHR-95-BLK parts, consider: cable diameter, whether you need moisture sealing, expected ambient temperature (South African conditions can vary from cool labs to hot workshops), UV exposure for outdoor runs, and mechanical strain. Check connector types (screw terminal, barrel, JST, Molex) to ensure sleeves and boots fit over plugs or can be applied before assembly.

Accessory bundles & complementary parts

• Heat gun or controlled soldering iron for even shrink application
• Cable ties, adhesive-lined wrap tape, and label sleeves for identification
• Strain relief boots sized to connector bodies and panel cutouts

Practical Examples & Simple Calculations

Example 1: Insulating a 2.1mm DC barrel solder joint. If the barrel outer diameter after solder is 4.5mm, select a heat-shrink tube with an expanded ID >= 4.5mm and a shrink ratio that reduces to about 2-3mm final ID. A 3:1 tube of nominal 9mm expanding to 4.5mm then shrinking to 3mm would suit.

Example 2: Bundling a 6mm harness. Use braided sleeving with a minimum expanded diameter of 7-8mm to allow for movement; choose PET sleeving for abrasion resistance in moving installations.
