Hammond Manufacturing's 1553T range of T cases is designed for use in a wide variety of hand-held instrumentation, data capture, and controller applications across all industries. Initially available in two sizes, 6.50 x 3.15 x 1.10 inches (165 x 80 x 28 mm) and 8.27 x 3.94 x 1.26 inches (210 x 100 x 32 mm), the enclosures feature recessed areas for keypads and displays and are available with or without a battery compartment. Versions without a battery box have two removable end panels; the battery versions have a single panel at the top of the unit. The battery box in the larger unit accepts four AA or two 9 V cuboid batteries, two AA or a single 9 V in the smaller; connectors for both types are supplied. The removable plastic end panels are easily machined to provide cutouts to suit LEDs, connectors, and switches as required.
Molded in flame retardant ABS, the units have a smooth curved shape that fits comfortably into the hand. They are produced in light grey or black, both with over-molded, contrasting soft side grips as standard. Both top and base provide with PCB mounting standoffs and the two shells are assembled together with screws into brass inserts, allowing repeated access to the interior without degrading the closure.
