In the Hammond 1553 enclosures series now can be found also types with a sufficient space for a keyboard and display.
Series of ergonomic handheld enclosures – 1553 is familiar to many of you. All types from this series provide a reliable grip thanks to a pleasant side overmold, they feature the same shape and they´re available in various sizes. That´s why, it is possible to choose the type exactly bespoken to your requirements. However there was a limitation, if you wanted to use a relatively large keyboard and a spacious display.
This problem is solved by the novelty – 1553T series. It provides a sufficient space for a keyboard and display and at the same time, it is somewhat thicker than other types of 1553 series, what enables to use several PCBs stacked on each other. That´s why, the 1553T series is ideal for various hand-held instrumentation, controllers, data capture and similar applications. The display and keyboard areas are recessed, what provides an additional protection (suitable also for membrane keyboards). 1553T enclosures are available in a black and a light-grey version and also with the battery compartment (battery contacts are included). Removable end panels (1 or 2 depending on version) enable easy modification and a trouble-free usage of connectors, IR components and other.
From a hand-held device, we naturally expect a higher dust and water resistance, what 1553T series with IP54 protection meets sufficiently. Last but not least – a relatively robust construction from a flame retardant ABS plastic and brass bushings give an assumption of a long lifetime and durability.
All 4 versions became our stable stock items, detailed drawings including 3D viewings can be found in datasheets at particular types. On the Hammond website, you can also find CAD files and 3D models. In case of interest in any HAMMOND products please contact us at firstname.lastname@example.org.

Company Hammond Manufacturing is probably familiar to you in context with high quality aluminium and plastic enclosures. But Hammond Manufacturing also produces a wide range of audio transformers, chokes and lamp transformers.
Audio transformers are mainly known to those, who work with professional sound equipment, microphones and high-end lamp amplifiers. A main function of transformers in audio devices is above all impedance matching. Various audio signal sources, like for example microphones, have an impedance different from impedance required for further signal transmission. Naturally, without impedance conversion, a direct connection into a transmission chain would cause a significant change of signal level, moreover frequency dependent, lower resistance to interference, or an overload of an end stage (at a lamp amplifier). At the same time transformers provide a galvanic disjunction, thus their usage is often convenient also from safety reasons.
Advantages / Features:
- top quality
- balanced frequency response
- low insertion loss
Hammond Manufacturing has long-term experience with a development and production of audio transformers. In a production portfolio we can find various series, from simple ones up to top wideband series, like for example the 850A series with a frequency response +/- 0.5 dB from 20 Hz to 20 KHz. Another group of components consist of lamp transformers. Here we can find output transformers, supply transformers, chokes, but even drivers and also many construction components.

Precise construction, many mounting options of internal components and resistance to dust and water – all this will provide you the Hammond 1554 enclosures series.
Plastic enclosures Hammond 1554 series are designed with emphasis on a water and dust protection of components and devices. This is ensured by a proper two piece “tongue & groove” lid construction and by a replaceable pre-formed silicone gasket seal. Thanks to these details, enclosures meet IP66 class. Lid is secured with M4 stainless steel machine screws (included), threaded into integral stainless steel bushings (for repetitive assembly & disassembly). The same material of screws and bushings avoid corrosion caused by dissimilar metals. Secure mounting of inner components secure four M3 threaded integral brass inserts and/or standoffs. Vertical placing of PCBs is also possible thanks to molded guides (for 1.5mm thick boards). The enclosure can be mounted to a wall or shelf through the back of the enclosure, with openings outside of the gasket seal.
Hammond 1554 series contains types of various sizes, made of ABS – UL94 HB, polycarbonate – UL94 V0 and also versions with transparent or smoked lids. Enclosures made of polycarbonate are UV stabilized and recommended for outdoor use. Types made of ABS are recommended for indoor use only. Upon request are also available galvanized steel inner panel and mounting feets.
From our stock we offer you 1554FGY made of ABS and two types made of polycarbonate – 1554C2GY, 1554C2GYCL – with a transparent lid. Detailed information will provide you the Hammond 1554F and 1554C2 datasheets. On the Hammond website are also available the files for AutoCAD and 3D models.
