Product Selection Guide
Front Mount vs Rear Mount
LF07WBR-3P Male Pin Front Mount
Power input or signal output from the device exterior.
Designed to be inserted from the exterior of the panel, front-mount connectors are ideal for devices where internal access is restricted after final assembly. They offer easy external maintenance and a classic, rugged look.
LF07WBR-3S Female Socket Front Mount
Power output with built-in finger protection.
Designed to be inserted from the exterior of the panel, front-mount connectors are ideal for devices where internal access is restricted after final assembly. They offer easy external maintenance and a classic, rugged look.
LF07WBRB-3SD Female Socket Rear Mount
Internal installation for tamper-proofing and flush finishes.
The LF07WBRB-3SD is engineered to install from the inside (rear) of the panel looking out. This creates a clean, flush aesthetic on the device exterior and protects the connector from being tampered with from the outside. The straight solder contacts make it perfect for tight, compact internal wiring layouts.
