Amphenol Commercial FLM Zhaga Book 20 Dali Interface Connectors

Amphenol Commercial FLM Zhaga Book 20 Dali Interface Connectors are DALI interface connectors for indoor luminaires. The FLM series is compliant with Zhaga Book 20, which specifies two-position connectors identified as Luminaire Extension Module Receptacles (LEX-MR) and Luminaire Plugs (LEX-LP), used for DALI-2 (Digital Addressable Lighting Interface) applications. DALI-2 is a smart interface protocol between indoor luminaires and sensors and communication modules. Amphenol standardized Book 20 FLM series connectors allowing modules to connect to the LED driver and control system. The modules can be easily field serviced and replaced when necessary.

The modules can be easily field serviced and replaced when necessary. The FLM connectors are available in wire-to-wire and wire-to-board configurations. The pin contact connectors (LEX-MR receptacles) are available as a right angle or vertical PCB mount with SMT tails, or as wire termination housings for use with crimp contacts (purchased separately). The socket contact connectors (LEX-LP plugs) are available for use with wire crimp contacts (purchased separately), or with integrated contacts with poke-in wire termination.
