Smart Solid State Relays detect compressors load failures

An ultra-low temperature (ULT) freezer is a refrigerator that stores contents at between −40 to −86 °C (−40 to −123 °F), usually dedicated to life science applications such as new generation vaccine storage. ULT freezers are commonly fitted with alarm systems that will remotely alert designated parties in the case of a freezer failure.

Vital for control panels to cool increasing ambient temperatures between -15…+75°C, Finder’s 7F Series keeps internal devices working at optimal levels, while also preventing dusty or contaminated air from entering the panel, allowing for smooth operating systems. Reverse flow versions are also available.

With its slim construction and wide range of sizes, the 7F can slip into some of the most compact of panels and takes minimal depth within the enclosure, offering a time-saving installation and maintenance for installers. New size 4 filter fans are available with 250 and 400 m3/h.

Available in 24V DC, 120 and 230V AC (50/60 Hz), Finder’s cooling fans and filters offer a flexible, reliable and competitive range, along with Finder’s premium quality reputation. The 7F Serie’s air volume is (24...400)m3 /h (free flow) with air volume (14...270)m3 /h (with Exhaust Filter installed in cabinet).

Finder’s 7F Series also has a replaceable G3 rated filter mat which can be removed quickly and tool free. The size of the Exhaust Filter should match the size of the Filter Fan to achieve the best ventilation within the cabinet. Safety is ensured with the filter mats with a DIN F1 fire rating and other plastics comply with UL 94 v-0.

1-Phase High Current Choke in Vertical Design
• Small footprint on the printed circuit board
• Open design optimizes heat dissipation
• Compact and lightweight
• Nanocrystalline or ferrite ring cores

Schurter expands its range of current-compensated chokes for printed circuit board mounting, to include a series for 1-phase high-current applications. Due to the vertical design, the new DKIV-1 series sports a significantly smaller footprint. The chokes are available with a ferrite or nanocrystalline core for rated currents from 10 A to 50 A. The open design makes the chokes particularly compact and lightweight.

Like all other aspects of electronic design, the power circuit is oftentimes built today using discrete components on printed circuit boards. With the trend toward integrating components, to achieve smaller and smaller form factors, thermal problems and high current on the PCB can become a challenge. Traditional block filters might well address these challenges, but their larger package size also presents challenges due to the mentioned space constraints; therefore, an effective asymmetrical common mode choke, together with capacitors mounted on the PCB, is a better solution

Compact and Lightweight
The new DKIV-1 series is designed for 1-phase applications at rated currents from 10 A to 50 A. Even at the max. rating, the vertical choke requires only a small footprint on the PCB, thus allowing a compact design with high performance. The compact and lightweight current-compensated chokes are throughhole mounted. They are ideal for multistage filter applications, where the combination of a vertical choke (DKIV) with a horizontal choke (DKIH) reduces the mutual interference of the magnetic fields of the individual chokes.

Performance and Approvals
The DKIV-1 current compensated chokes comply with IEC 60938 and with a rated voltage of 300 VAC or 450 VDC, they are suitable for almost any application. The DKIV-1 series is certified for current ratings from 10 to 50 A, 300 VAC according to IEC and UL and 10 to 50 A, 250 VAC according to CSA. The chokes have ENEC and cURus approvals. The DKIV-1 series has been designed for a wide temperature range of -40 °C to +100 °C.

New DFH02 plastic PCB fuse holder with optional transparent insulation cover from Hylec for PCB and thru-hole mounting

Vertical orientation; 22.6mm pitch, UL94V-2 polycarbonate cover

Hylec-APL, the specialist supplier of electrical components and enclosures, has launched a new 5mm x 20mm PCB fuse holder, the DFH02, for either PCB or thru-hole mounting. The DFH02 features a transparent insulation cover which provides protection for the fuse and makes installation and removal simple. This style of fuse holder is the most popular and best-selling type of fuse holder on the market.

Suitable for use in all types of circuits, Hylec’s DFH02 PCB fuse holders provide a secure and safe method for mounting fuses on all types of PCBs and eliminate the problems associated with using fuse clips on a PCB. Easier to install than fuse clips, DFH02 fuse holders are also low-cost and ensure a reliable electrical and mechanical connection.

The 22.6mm pitch DFH02 can be mounted direct to the PCB in horizontal orientation or thru-hole mounted for vertical orientation. Electrical rating is 6.3A at 250VAC maximum.

The base material is thermoplastic, PA66 glass-filled, offering mechanical strength and excellent dimensional stability. It meets UL94V-0 flame-retardancy standards. The transparent insulation cover is rated UL94-V2.

Dimensions of the DFH02 base are: 13.5mm high off the PCB, width 9.0mm, 22.0mm long. Pin pitch is 22.6mm. Total height with cover off the PCB is 15.0mm.

A low noise SQ57 DC brushless motor drives the pump vacuuming mosquitoes

Zika virus, dengue, chikungunya and yellow fever are primarily transmitted by the bite of an infected mosquito. To date, A total of 86 countries and territories have reported evidence of mosquito-transmitted Zika infection with no vaccine yet available for either prevention or treatment.

Development of a Zika vaccine remains an active area of research. In the meantime, smart technology has revolutionized mosquito control by creating mosquito traps which pose no danger to people or our ecosystems.

Marine engine controls benefit from ZF Hall-based position sensors

Hall-based position sensors are becoming widely used in a wide variety of applications due to their contactless and wear-free measurement method. These sensors are used in outboard marine engines to control the trim level. Marine drive manufacturers rely on the Hall-based position sensors from ZF as reliable and robust components for their overall drive system.

The Hall-based position sensors from ZF have been established as a reliable sensor solution for marine applications, especially for the inclination and trim measurement of outboard motors. To ensure optimal performance of a boat depending on the speed, the outboard motor must have a certain inclination. Both angle and linear position sensors are used with an associated external magnet carrier to monitor and realign the current inclination of the motor. The sensors are completely contactless and have an almost unlimited lifetime, as no wear and tear occur caused by abrasion. For position measurement, the external magnet is attached a few millimeters above the sensor. If the magnet rotates, the magnetic field changes, which again leads to a change in voltage within the sensor electronics. Each voltage value can be assigned to a specific angle value.

Depending on the requirements and customers’ requests, ZF offers a range of different angle sensor variants with associated magnets for triggering signals. These vary in terms of the angular range (0-360°), signal redundancy (non-, semi- or fully redundant), connection interface (cable, connector), operating temperature range and form factor. Attributed to long lasting experiences and know how in hall-based sensor technology, also customized solutions can be fulfilled.
