1551V sensor enclosures for the IoT
T Series enclosures from BCL Distribution provide ideal small ABS enclosure solution for multiple uses
Strong, easily modified for specific requirements; supplied with lids

he new 1551V miniature ventilated sensor enclosures from Hammond Electronics are designed to house
sensors and small sub-systems installed in the manufacturing environment as part of IoT systems. While there is no relevant international standard, the 1551V enclosures are designed around the PCB sizes selected by leading sensor manufacturers for their latest generations of products. The ABS UL94-HB 1551V is available in black, grey and white as standard; four plan sizes, 80 x 80, 80 x 40, 60 x 60 and 40 x 40mm are all 20mm high, maximum PCB sizes are 74 x 74, 74 x 34, 54 x 54 and 34 x 34mm respectively. Four PCB mounts are moulded into the base and the 20mm height gives enough space for board-
mounted RJ45, USB and other standard communication interfaces. To simplify access, the snap-fit closure allows repeated opening and closing without tools. There are ventilation slots on all four vertical faces and mounting slots and a 15mm cable knock out in the base. Environmental sensors monitoring basics such as temperature, humidity and pressure are widely installed, and are now increasingly intelligent sub-systems, with data processing and communications capability embedded on a small PCB. For active components that produce relatively large amounts of waste heat, the 1551V obviously provides excellent airflow for cooling purposes.

ollowing the recent announcement of the expansion of its business, BCL Distribution, the specialist UK manufacturer of standard and custom plastic enclosures, has expanded its T Series enclosures of small multi- purpose boxes. Specifically designed to be a flexible solution for multiple applications, T Series enclosures can be easily modified by drilling or punching to suit specific customer requirements.
The T Series is supplied complete with lids, which are retained with four countersunk self-tapping screws, and is available in six different sizes. The T1-26 model measures 40mm x 28mm x 18mm and has a wall thickness of 1.0mm; the HBT3 model measures 73.5mm x 51mm x 25.5mm with 1.75mm wall thickness; T2 models are 75mm x 56mm x 25mm with 1.5mm thick walls; the T3 model measures 75mm x 51mm x 27mm, also with 1.5mm walls; T4 enclosures are 111mm x 57mm x 22mm with an increased wall thickness of 2.0mm; the largest enclosure is the HBT4
model at 113mm x 59mm x 24mm, with 1.75mm thick walls.
The T1-26, HBT3 and HBT4 are in a matt finish, whereas the T2, T3 and T4 have a polished finish. Packs of either black passivated countersunk posidrive or zinc plated posidrive screws for lid retention are available separately, all in quantities of 100. Available standard colours are black, white or light grey, and other RAL colours are available on request. Silk screen printing is also available
bcldistribution.com Gold plated 75 BNC FeedThrough connecter provides 12GHz connectivity
Cliff Electronics has launched a gold plated 75 BNC connecter offering a 12GHz bandwidth suitable for 4K format video and other high frequency signals
T
he new BNC to BNC FeedThrough connector is mounted in a recessed socket plate, which fits the industry standard 24mm XLR panel cut-out adding this BNC connector to the very successful Cliff FeedThrough connector range. The Cliff FT series of true feed through data connectors for audio, video, electrical and electronic instrumentation are perfect for developing custom I/O configurations for wall plates, enclosures, rack panels, etc. All fit within a standard XLR panel cut-out and use standard cabling for front and back connections with no soldering or screw terminal connections required. FT connectors have countersunk mounting holes may be assembled from the front or back of a panel while a low rear profile accommodates the tightest behind-the-panel spaces. Key specifications include; 12GHz, 75 impedance,
frequency range 0-18 GHz, dielectric withstand voltage 1500Veff, insulation Resistance 5000M , operating

temperature range -35°C to +70°C, contact retention 10N min, mating cycles 500 cycles. John Hall, managing director of Cliff Electronics, comments: “Our new gold plated BNC connector offers our customers a 4K video standard connector future- proofing broadcast systems and patch panels and offers industrial users a high-reliability, low contact resistance connector for sensors, instrumentation and test and measurement. We can also supply our new gold BNC connectors pre-assembled into rack panels offering systems integrators fast and convenient system assembly.” Cliff’s XLR format FeedThrough connectors take advantage of the standard 24mm panel cut out widely used in audio and broadcast systems and which is finding increasing popularity instrumentation, medical and industrial applications due to the format’s flexibility, security and reliability. Versions available include GJ45, HDMI, BNC and USB3.0 compliant single and dual USB versions in addition to the existing range which provides Analogue, Digital and Optical Feed-Through connectivity in formats including Firewire, HDMI A-A and 50 ohm BNC versions, USB2 A-to- B and B-to-A “gender change” sockets high speed USB Type – C, USB3 to USB3 in all gender changing configurations - A-A, A-B and B-A. Also available are all popular data and Ethernet connectors including USB 2.0 and 3.0, LC and SC fibre (Duplex & Simplex), UTP and FTP RJ45s in both Cat6 and Cat5e (shielded and unshielded), Toslink, RCA Phono and HDMI and blanking plates.
All versions of Cliff’s XLR footprint connectors are in full
production and available direct from Cliff and via major Distributors in the UK and Europe.
