Sanwa’s All in One LC Adapters meet the needs of applications where the adapter must install tightly and be resistant to vibration. Designed with metal plates on all sides of the adapter that expand to tightly fit into the panel, these adapters provide a secure, vibration-resistant fit.The All in One LC Adapters come with dust protection shutters, which are designed to cover the entire coupling hole. These built-in shutters are automatically opened as the LC connector is inserted, and closed as it is extracted, providing a barrier against dust and protecting workers’ eyes from laser exposure.FEATURES Insertion loss (typical); 0.2dB or less IP 5x No Dust Cap required on front side Laser protection, white translucent shutter available UL94V-0 flammability grade RoHS and REACH compliant IEC61754-20, TIA/EIA 604-10A, GR-326-CORE compliant
