Acromag Vwb2000 Point To Point Wireless Io Modules

Components: Essential Actors in Supporting Roles

Nov. 17, 2020

This month’s product focus features several products in the components family—essential actors in supporting roles for the controlled flow of electrons in circuits. These products challenge the frontiers of quality, durability, and size in the industry.

Point-to-Point Wireless I/O Modules

Acromag broadened their Vertu instrumentation family with the VWB2000 signal wire replacement system. Provided in a rugged NEMA 4X/IP68 industrial housing, the point-to-point wireless signal bridge takes analog, discrete, or Modbus signals at one location, and reproduces them at a second. The system consists of two pre-paired transmitter/receiver units with a range of 1 mile outside, or 500 feet indoors, which can be extended using wireless repeater units or high-gain directional antennae. An LCD display provides signal strength and other diagnostic information. Acromag

Linear Actuators

Moticont has introduced the DDLM-019-044-01 non-commutated linear actuator. This compact, zero cogging, clean, quiet, and fully-enclosed linear actuator is 0.750 in. (44.5 mm) long with a stroke of 0.460 in. (11.7 mm). This linear actuator can develop up to 11.0 oz. (9.7 N) peak force. Direct coupling of the actuator to the load results in zero backlash, and allows for smooth, high acceleration/deceleration, and high-speed positioning. Moticont

Positive Slope Equalizers

Pasternack’s latest positive-slope equalizers compensate for gain variation in systems where excessive losses may occur at the low end of the frequency band. They are suitable for a variety of applications like aerospace and defense, MILCOM and SATCOM, test and measurement, and wireless infrastructure. The family consists of 18 models operating over octave frequency bands from 500 MHz to 40 GHz. These 50-Ohm designs have fixed equalizing values from 2 to 8 dB, at the minimum frequency, and produce an attenuated response that increases linearly across the frequency band. Pasternack

Bel Fuse-Circuit Protection Announces 0680L Series of Slow-Blow 2410 SMD Fuses

Bel Fuse-Circuit Protection’s 0680L Series of ceramic surface-mount fuses offer inrush current-withstand capability in a 2410 SMD package. These slow-blow fuses are designed for automotive and other applications that require high DC voltage ratings and high DC interrupting ratings. Bel’s 0680L Series fuses are compatible with the 260º, IR Pb-free solder process. They are available in current ratings from 375 mA to 12 A and an operating temperature range from -55º to 125ºC. These fuses are also AEC-Q200-compliant, RoHS-compliant (with exemption 7(a)), halogen-free (MSL = 1), and lead-free. Bel Fuse

EMC filters

Two MAF1608GAD-L noise-suppression filters, designed for audio lines, have a footprint of 1.6 x 0.8 mm each and an insertion height of 0.6 mm. They offer rated currents of 3.2 and 2.3 A, respectively, and DC resistances of typically 0.021 and 0.045 Ω. Their impedance at 900 MHz is 120 and 200 Ω, respectively. Their low DC resistance and rated current of more than 2 A make them suitable for smart speakers and external speakers for tablets that require power levels of 2 W or higher as well as for headphones and microphones. TDK Corp.

Dual n-channel 60-V MOSFET

A common-drain dual n-channel 60-V MOSFET in the compact, thermally enhanced PowerPAK 1212-8SCD package can increase power density and efficiency in battery-management systems, plug-in and wireless chargers, DC/DC converters, and power supplies. The SiSF20DN offers an RS-S(ON) down to 10 mΩ typical, at 10 V in a 3x3-mm footprint. The vendor reports this value is 89% lower than its previous-generation devices, resulting in reduced voltage drop across the power path and minimized power loss. The device uses an optimized package construction, with two monolithically-integrated TrenchFET Gen IV n-channel MOSFETs in a common-drain configuration. Vishay Intertechnology

Choke for Automotive Ethernet

The DLW32MH201YK2 common-mode choke coil (CMCC) for  Automotive Ethernet (100BASE-T1) withstands temperatures ranging from -55 to +150°C, which compares favorably to the -40 to +125°C temperature range of conventional products, the vendor said. This improved performance has been achieved by employing metal termination that absorbs the stresses associated with temperature change as well as by optimizing the combination of the vendor’s original materials and product design. Features include a 3.2-mm x 2.5-mm size, compliance to AEC-Q200 (a specification defined by the Automotive Electronics Council), and a rated voltage of 80 V. Murata Manufacturing Co. Ltd.
