BCL Enclosures launches new IP66-rated stainless steel BEDSS Series door enclosures
Flexible, Accurate, Slim & Resilient
Semitec’s Gymnastic NTC Thermistor
gold medal in gymnastics! The JT can literally bend over backwards to solve your temperature sensing problems. Worldwide winner, the Semitec JT has been used
I
extensively in many space-sensitive applications including skin/surface sensing, various wearable technologies including blood-glucose monitors, prismatic & pouch batteries and CPU/IC monitoring. Slim but strong, the JT is only 0.5mm thick at its sensing
tip making it the thinnest flexible NTC available. Laminated between two polymer layers makes it both flexible and resilient. The flexibility allows the JT’s sensor to be placed closer to the heat source delivering optimum temperature control. The Semitec JT also operates in extreme temperatures
from -50°C to +125°C with highly accurate 1% R25 tolerances. With excellent electrical insulation the JT thermistors can safely be used where they might come into contact with adjacent live components. Putting it simply, our JT thermistors outperform other
slower, larger inflexible competitors! Contact us for comprehensive technical advice, samples and bespoke customer solutions.

EDSS Stainless Steel Series lockable, solid door enclosures are specially designed to provide high-quality, secure protection for
specialist and demanding electronic and electrical installations. IP66 rated to protect contents against water and dust, they withstand impact to IK10 specifications and extremes of temperature ranging between – 20degC and +55degC. Suitable applications include corrosive environments, such as those found in the chemical and petrochemical industries, plus those where strict hygiene is required, for example, the agro food sector, hospitals, dental and veterinary practices,. Optionally, BEDSS enclosures are available in corrosion- free marine grade 316 stainless steel versions for installations subject to salt water. Supplied as a complete kit with a metal lock and key, a pre-wired earth strap fitted between the door and
the housing, and a 2mm galvanised steel back mounting plate with spacers. BCL Enclosures

New icotek KEL-DP time and cost saving alternative to traditional cable glands now available from Foremost Electronics
additions to icotek’s market leading range of cable entry plates, the KEL-DP 25 version A and KEL-DP 32 version A and B. KEL-DP products offer high cable density and are a simple to use cost saving alternative to traditional cable glands. The KEL-DP is a hygienic design, free of dirt-collecting recesses and provides environmental protection IP65 / UL type 12. The new products fit standard metric M25 and M32 cut-outs and, depending on the model up to 13 different cables can be inserted through a single gland. The KEL-DP range can accommodate cable diameters from 5.2 to 8mm.

attery storage systems store excess energy produced by Renewable Energy systems such as
PV or Wind and store it for use when needed. This counterbalances the fluctuation between energy production and demand for electricity. The importance of such equipment makes interruption of their service unacceptable, so measures must be taken to limit damage due to external influences. One of the risks to be taken into account is possible damage due to transient overvoltage’s generated by lightning or by switching operations. Specialist manufacturers of Battery Storage Equipment have noted a reduced robustness in impulse overvoltage of this type of equipment’s – particularly in battery systems - and due to the imperative need for continuity of service they recommend the use of surge protectors at their terminals. Due to the maximum DC operating voltage often being very high (1000 Vdc and more), an SPD correctly specified for the application is

necessary and for it to be compatible with these voltages and in conformity with the forth coming IEC61643-41. Due to the unique characteristics of Battery Energy Storage systems, standard DC or PV SPD’s are not suitable for use with this type application due to the potentially extremely high short circuit current (up to 100kA or more). Citel have designed from the ground up the
DDC50S-21Y specifically for Battery Energy Storage Systems. The DDC50S-21Y is a Type 2 SPD available with either 500, 800, 1200 or 1500VDC Max operating Voltage (Uc), an In (Nominal Discharge current) of 20kA, an Imax of 50kA and importantly an Admissible short-circuit current (Isccr) of 100,00A. It is DIN rail mounted and as such easy to install in any standardized distribution panel or control cabinets.

he new-look Sangamo range of timers and heating controls can be broken down into four main product
categories - Timer Controllers, Thermostats, Programmable Thermostats and Programmers – with a total of 15 products making up the comprehensive range.
Timers - designed for simplistic ON/OFF manual or scheduled control for heating and lighting applications. The range has been expanded with a total of three new products, each one introducing the addition of a fused spur switch for additional protection for high loads.
Thermostats - designed for controlling heating system via an electronic sensor – now totals five products.
Programmable Thermostat products - designed for controlling heating applications via an electronic sensor or programmed schedule, and ESP has added one new product to this range. All thermostat products have been upgraded and now offer TPI (Time Proportional and Integral) control for heating efficiency. In addition, the programable thermostats include an optimization feature; Optimum Start/Delay Start and Optimum Stop, for extra efficiency.
