Handheld plastic electronic instrument enclosures

30 March 2022 Enclosures, Racks, Cabinets & Panel Products

Hammond Manufacturing’s 1552-Series handheld enclosures are available in six sizes. All models are 50 mm wide and either 22 or 30 mm high, with three length options available: 70 mm, 110 mm and 150 mm.

The IP54 flame-retardant ABS plastic units feature an ergonomic design that fits ergonomically in the hand, enabling it to be used comfortably for long periods in applications such as a machine controller or an electric hoist control. An optional wall-mounted holder allows the enclosure to be stored in a convenient location when not in use. It can also be used as a desktop enclosure.

Lap joint construction protects the housing’s contents against dust accumulation and water, and an integral cable clamp keeps internally routed cables firmly in place without damage. Both end plates are removable for easy machining and are swappable with an integrated TPU cord-grip end-panel, which provides input/output and strain relief solutions for cables.

When device storage is required for applications such as medical instrumentation, a wall-mounted holder is available as an accessory. Built-in features include internal PCB standoffs, a recess on top for seamless installation of membrane keypads, and a lightly textured surface that retains its initial lustre even when subjected to minor blemishes such as light scratches or fingerprints. Each enclosure is secured with four self-tapping screws, and snap closures are fitted in the centre of longer units to prevent bowing.

The enclosures are moulded in a choice of black or grey flame-retardant, UL94-V0-rated ABS plastic with a satin texture; black models come with black screws while grey models come with nickel-plated screws. Cable gland end-panels are made from flexible TPE and hard polycarbonate, and cable tie-down accessories are moulded from polycarbonate, all of which are rated to UL94-V0.

Optional accessories include a cord-grip end-panel kit which replaces the standard end-panel and fits securely into the enclosure. These kits are compatible with wire diameters from 2 mm to 6 mm, and allow the cable to be secured inside the case with a cable tie-down and screws.

A plastic wall-holder accessory (also optional) allows the enclosure to be temporarily fixed to a wall with mounting holes which are countersunk for flat-head screws.
