DF36A-40P-SHL from Hirose Electric Co Ltd is a rectangular connector accessory shield designed for use with the DF36 Series and 40-position connector configurations. In practical designs, this type of accessory is typically selected to support connector protection, mechanical integrity, and signal-interface reliability in compact electronic assemblies. Engineers may consider it for industrial equipment, embedded systems, consumer devices, and other interconnect applications where a matched DF36 accessory is required. Based on the provided specifications, the product status is listed as Active, which is a positive indicator for ongoing sourcing and design continuity. However, lifecycle status is also separately marked as unknown, so procurement teams should still confirm current manufacturer support before committing to long-term programs. RoHS compliance information is not explicitly provided in the supplied data, so compliance should be treated as information not available pending verification through official Hirose documentation or manufacturer confirmation. For regulated builds, engineers should also verify REACH status and any material declarations before release to production.
