Direct answer

What this result means

Compare the complete cable OD interval with a declared gland sealing interval and identify the controlling dimensional margin. The relationship M = min(Dc,min − Dg,min, Dg,max − Dc,max) ties minimum cable OD, maximum cable OD, minimum gland range and maximum gland range directly to the reported result. Cable and gland ranges are stated in the same diameter convention. Treat the value as a transparent preliminary calculation, then compare it with the actual cable-entry assembly and current product documentation.

Use sequence

From measurement to review

  1. Confirm minimum cable OD and maximum cable OD from a controlled drawing, measurement or project document.
  2. Apply M = min(Dc,min − Dg,min, Dg,max − Dc,max) with consistent units and keep the entered values beside the result.
  3. Use lower-range margin only after checking both cable limits, the exact gland sealing range and measurement tolerance.

Limits

What this calculation does not confirm

  • Cable and gland ranges are stated in the same diameter convention.
  • Inputs describe one defined operating or measurement condition and use mutually consistent units.
  • The result does not by itself confirm product suitability, standards compliance, ingress performance or installation approval.

Calculator FAQ

Use the number without losing the engineering context.

These answers clarify what the tool calculates and where a product-specific review still begins.

01Calculator guidanceHow does the cable OD range margin calculator calculate lower-range margin?

The tool applies M = min(Dc,min − Dg,min, Dg,max − Dc,max) to minimum cable OD, maximum cable OD, minimum gland range, maximum gland range. Cable and gland ranges are stated in the same diameter convention. Keep the displayed units with the result so the calculation can be repeated.

02Calculator guidanceWhat does lower-range margin show for this sealing range margin review?

Compare the complete cable OD interval with a declared gland sealing interval and identify the controlling dimensional margin. It is a preliminary engineering value, not confirmation of a cable-gland model, standards compliance or installation approval.

03Calculator guidanceWhat should be checked about both cable limits before using the cable OD range margin calculator result?

The equation does not model both cable limits, the exact gland sealing range and measurement tolerance. Confirm those conditions against the actual cable-entry assembly, applicable requirement and current product documentation.
