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!
