Best Practices
Slack & Allowance Guidelines
Recommended slack percentages for different applications.
3-5%
Fixed Installation
For stationary equipment where cables don't move after installation.
5-10%
Moderate Flex
For applications with occasional movement or vibration.
10-15%
Dynamic Motion
For moving machinery, robotics, and high-flex applications.
0.15-0.3m
Service Loop
Extra length at connections for termination and future servicing.
Cable Length Planning Tips
- • Always add slack for cable routing around obstacles and bends
- • Service loops allow for connector retermination and field service
- • Account for connector entry depth and strain relief length
- • Consider thermal expansion in extreme temperature applications
- • Add extra for prototype builds to allow for design changes
