IP64 sealing is achieved by a tongue and groove joint between the two covers and secondary seals behind the end panels that keep them in close contact with the inside face of the covers. On the hand-held range, the top cover features a recessed area to accept either a 60 x 96mm or 40 x 74mm membrane keyboard or label, and an industry standard 57 x 21mm or 37 x 17mm LCD cut-out, for which mounting bosses are moulded into the case. The instrument case range features include optional battery compartments, which will accept either 2 or 4 PP3, AA or AAA sized batteries and a choice of moulded or anodised aluminium end panels. The metal panel would normally be used at the rear for I/O and power connectors with the plastic panel at the front for aesthetic reasons.
A range of dedicated development PCBs are available and vented end panels, additional PCB mounting hardware and rubber feet fit all sizes of enclosure. Belt clips, a tilt stand/carry handle option, shallow and deep battery compartments and clear acrylic LCD windows are also available.
All sizes can be supplied with an internal copper-silver painted coating to provide EMC capability; typical attenuations are better than 95dB at 1MHz and 46dB at 1GHz. All sizes can be moulded in many different materials and colours; milling, punching or drilling of apertures for pushbuttons, connectors and indicators and silk screening of both the enclosure body and end panels is available.
