PCB terminal blocks for LED lighting

Harting announced the introduction of its new white coloured, 2,54 mm pitch SMT har-flexicon PCB terminal block connectors for LED lighting applications.
These new connectors support reliable long-term installation of LED modules (assembled from LED arrays mounted on rigid and thermally conductive substrates for optimal heat dissipation) into a wide variety of applications, e.g. high/low bay indoor lighting, street lighting, floodlighting and emergency lighting.
Applying har-flexicon with surface-mount reflow soldering processes greatly simplifies LED module PCB assembly. Connecting the conductors in lighting fixtures was formerly often done using hand soldering. This is often unreliable and prone to error when using printed circuit boards with a metal core, due to the high degree of heat dissipation. The optimised design of the har-flexicon connector hold-downs ensures rugged solder-pad retention and supports reliable handling during equipment final integration.
PCB mounting design options include a horizontal male and a discrete wire push-in spring-cage terminal block part. Both are made from high-temperature LCP plastic which is completely colour-stable after the SMT assembly process and UV resistant for long-term installation. As a result they minimise shadowing effects within the light fixture. Pluggable female, discrete wire, push-in spring-cage cable connectors are also available. These have a strong but flexible locking-latch design which is highly damage resistant and ensures dependable mating.
Harting’s discrete wire, push-in spring-cage termination design offers resilient cable retention whilst allowing simple reconnection for easy light fixture maintenance. The product family comprises 2- and 3-way versions for stranded and solid conductors with cross-sections up to 0,75 mm², at a nominal current carrying capacity of 6 A.
