Hammond Electronics has added the AA, the A and C sizes to its 1553 family of soft-sided, hand-held enclosures. These models feature an ergonomic curved shape that fits into the hand. The AA measures 75x50x17mm, the A 100x61x17mm and the C size is 117x79x33mm and is available with or without a battery compartment. The C size is a deeper version of the existing B size, which has a depth of 24mm. The enclosures are available in RAL 7035 light grey or RAL 9011 black, both with RAL 7012 grey over-moulded soft side grips. The units are moulded in ABS and are suitable for housing small hand-held instruments, remote and flying lead machine controllers. The top cover is recessed and PCB standoffs are moulded into the base. Battery versions are available with clips for two AA and one PP3 batteries.
