FAIRPORT HARBOR, Ohio—Contract manufacturer MJM Industries said in a company release that it added over-molded junction boxes, also known as “Y-blocks,” to its line of M8 and M12 products. MJM Industries designs and manufactures custom over-molded cable assemblies, wire and cable assemblies, and flat flex and co-axial cable assemblies.
The company said that over-molded junction boxes are typically used where multiple M8 or M12 cable assemblies need to be spliced together. If an application requires 18 connectors, for example, a Y-block can help consolidate the assembly into six connections for a more efficient application. Because the over-molded junction boxes provide a higher level of ingress protection, they are said to be a cost-effective solution for harsh or rugged environments.
The Y-block assemblies from MJM Industries are customizable, offering multiple input and output configurations. Each cable has its own integrated strain relief. The junction box includes mounting holes and is made using a proprietary over-molding process to protect the internal wire connections and provide ingress protection to IP67 and beyond, the company said.
The internal wire connections can be mechanically spliced, soldered, or ultrasonically welded, and are reported to provide superior performance versus conventional splicing methods.
