Heyco® Pigtail™ Strain Relief Bushings
For Flat Cables, With Integral Nylon Spring |
Features |
|
- Protects the lifeline of your electric/ electronic products by absorbing forces of pull, push, twist, and flex.
- Securely anchors, insulates, and protects cables at panel entry points.
- Integral nylon spring eases the cable into a lazy bend; prevents sharp bending and assures longest cable and product life.
- Not recommended for applications where the power supply cord is subject to whipping or “jump rope” type motion.
- Adds reliability, longevity, and safety. Will pass CSA’s 50,000 cycle “vacuum cleaner” test (C22.2 No. 67).
-
- Standardize panel design! Fill unneeded SR mounting holes with Heyco Double “D” Plugs.
- SR hole punches and assembly tools.
