Waterproof optical connectors with built-in SC/LC-Duplex
SW20 Series
■Features
1. High optical performance and reliability
Internal SC / LC connector is the same structure as a
proven standard SC / LC.
2. Bayonet mating operation by one action
Lock release of SC / LC in conjunction with drawing of outer
housing.
3. Harsh environmental use
Waterproof in IP67 and corrosion resistance in 1,000 hours
salt mist
4. Standard SC/LC connector is available for testing.
SC/LC connector is available instead of SW20 plug.
