M8/M12 Circular Connectors
M12 Female PCB Connectors
ERNI introduced the first M12 SMT connector in 2003. The
ability for surface mount assembly processes contributes to
the design-to-cost philosophy and leads to significant cost
savings in general applications.
The modular connector system comprises of not only the
connector itself but also considers various threaded metal
flanges and O-ring seals. A solution that allows designer to
flexibly create different PCB to front panel distances.
Moreover it protects from dust and water immersion accor-
ding to IP67. Several codings compliant to IEC 61076-2-101
are supported.
