The 1551 miniature plastic enclosure family’s latest expansion comprises of 10 variants.

The 1551V ventilated sensor enclosure versions have now been extended with the addition of 1.77-, 2.13- and 3.15-inch (45, 60 and 80mm) diameter round versions, available with plain or vented covers. Also added to the 1551V range are unventilated cover versions of the 3.15 x 3.15, 2.36 x 2.36, 1.57 x 1.57 and 3.15 x 1.57 inch (80 x 80, 60 x 60, 40 x 40mm and 80 x 40mm) square and rectangular enclosures.

A key feature of the 1551V design is the snap-fit closure which maximizes the internal space for PCBs by eliminating screw fixings to secure the cover. The internal space available for PCB mounting is 2.89 x 2.89, 2.13 x 2.13, 1.34 x 1.34 and 2.89 x 1.34 inch (74 x 74, 54 x 54, 34 x 34 and 74 x 34mm) in the rectangular units and 1.54, 2.13 and 2.89 inch (39, 54 and 73.50mm) in the circular ones. All bases feature 0.16 inch (4mm) high PCB stand-offs, wall mounting slots and a 15mm cable knock out.

All sizes are 0.79 inch (20mm) high, which gives enough space for board-mounted RJ45, USB and other standard communication interfaces.
