Amphenol Commercial FLB Bases and Domes are designed to mate with the FLA series receptacles. The FLB base assembly offers a platform for a user-supplied printed circuit board assembly (PCBA) that provides photocell or other control functionality. The base utilizes twist-lock technology to provide a secure, integrated power-and-signal interface solution. The FLB domes pair with the bases to provide IP66 protection (per IEC 60529) for a mated photocell / control assembly. All base assembly components meet the UL 94V-0 flammability rating while the cover meets the UL 94-5VA flammability rating. The domes are available in a range of sizes and colors. Amphenol Commercial FLB Bases and Domes are ideal for use in roadway and area lighting applications.
