Hammond Manufacturing has released their new ABS UL94-HB, a 1551V miniature ventilated sensor enclosures designed to house sensors and small sub-systems installed in the manufacturing environment as part of IoT systems. The 1551V enclosures are designed around the PCB sizes selected by sensor manufacturers for their latest generations of products. Available in black, grey or white, there are four plan sizes ranging from 80 x 80 to 40 x 40mm which are all 20mm high. Four PCB mounts are moulded into the base and the 20mm height gives enough space for board-mounted RJ45, USB and other standard communication interfaces. To simplify access, the snap-fit closure allows repeated opening and closing without tools. There are ventilation slots on all four vertical faces and mounting slots and a 15mm cable knock out in the base. For active components that produce relatively large amounts of waste heat, the 1551V obviously provides excellent airflow for cooling purposes.
