M8 Metal Connectors: Shielded VS Unshielded

——This Guide Has All You Need for Selection!

In industrial settings, M8 metal connectors are the "go-to" solution for reliable signal transmission. But how do you choose between shielded and unshielded options? Follow these 4 steps to clarify your needs and avoid costly mistakes!

I. Core Difference: Shielding Layer – The Key to Interference Resistance

Shielded Connectors

Embedded metal layer blocks electromagnetic interference (EMI) for stable signals.
✅ Best for:

High-EMI environments (near motors)

High-speed data (industrial Ethernet)

l Precision sensors
✅ Advantages: Strong interference resistance, high protection (IP67/IP68).

l Unshielded Connectors

No shielding layer, simpler structure.

✅ Best for:

Low-interference environments (indoors)

Short-distance signals (on/off controls)

Budget-constrained projects

✅ Advantages: Lower cost, faster installation.

II. 4-Step Selection Method

l Is interference a concern?
→ Near high-power equipment? Shielded is mandatory to prevent signal corruption!

l What signals are transmitted?
→ High-speed data/analog signals? Shielded reduces jitter.
→ On/off signals? Unshielded suffices.

l Is water/dust protection needed?
→ Outdoor/humid environments? Shielded (IP67/IP68) is more reliable.

l What’s your budget?
→ Shielded connectors cost 30–50% more but offer long-term stability.
→ Unshielded connectors are cheaper, ideal for temporary setups.

III. Scenario Recommendations

Industrial robots: Choose shielded connectors with 360° crimp flanges (vibration resistance).

Outdoor sensors: Opt for IP68-rated shielded connectors (water/dustproof).

Indoor lighting: Go with unshielded snap-in connectors (low cost, quick installation).

Summary

Selection = Interference resistance needs × Cost efficiency.

Strong EMI/high-speed signals → Shielded.

Low interference/simple signals → Unshielded.

Pro tip: Always verify rated current, voltage, and mating cycles to avoid mismatches!
