Compact antennas are designed for Wi-Fi 6 and Wi-Fi 6E applications

Thu, Feb 10, 2022

Two series of three antennas each by Linx Technologies support Wi-Fi 6 and Wi-Fi 6E applications in the 2.4, 5.0 and 6.0GHz bands. Both series are compact and therefore suitable for IoT applications, said the company.

Antennas in the ANT-W63-MON series are compact monopole tilt/swivel whip antennas that work with multiple ground plane configurations. The hinged design allows for the antenna to be positioned for optimum performance. The MON series is available with an SMA plug (male pin) or an RP-SMA (female socket) connector.

The ANT-W63-WRT series are panel-mount di-pole antennas. The compact size allows low-profile mounting making them less likely to be accidentally damaged, said Linx. The WRT antennas are designed with an integrated counterpoise that eliminates the need for additional groundplane, making them suitable for applications with non-conductive or RF-transparent enclosures. The ANT-W63-WRT antennas are available in a variety of cable length and connector options, including SMA plug (male pin), RP-SMA plug (female socket), MHF1/U.FL type plug (female socket), and MHF4-type plug (female socket.

The antennas add 6GHz variations to the company’s WRT and MON product lines. CEO Tolga Latif, said: “With the continued expansion of Wi-Fi 6 in industry, . . . . customers will be better prepared to meet the growing demand for increased signal coverage and faster Wi-Fi 6 / 6E devices.”

The WiFi 6 antennas are available now from Linx Technologies’ distributor and manufacturer representative networks.

Linx Technologies strives to minimise the risk, delays, and technical challenges for design engineers to make products wireless and connect them to the IoT. Linx manufactures wireless components including antennas, RF connectors and cables, RF modules, and remote controls.

Arrow Electronics and Appletec agree compact camera modules

Tue, Jan 25, 2022

Fast prototyping for new designs and re-engineering existing products is assured following an agreement signed by Arrow Electronics with Israeli company, Appletec. As a result, Appletec will produce a range of compact camera modules (CCMs) exclusively for Arrow.

The CCMs are intended for developers who want to add an embedded vision capability to products used in sectors including industrial, medical, security and automotive. A customisation service will support a variety of interconnect solutions.

The choice of CCM will depend on a number of factors in the requirements of the application. For example, the amount of detail to be captured will determine the choice of resolution and frame rate, while the selected field of view (FOV) and depth of field will reflect the area to be covered.

The Arrow CCMs use CMOS image sensors from onsemi and can utilise the image signal processor (ISP) on the customer’s main board. Two fixed focus CCMs are available initially, offering 0.3 or 4Mpixel sensors and FoV ranging from 49 to 84 degrees. Frame rates range from 36.7 frames per second (at 720p) and 75 frames per second (at VGA) up to 360 frames per second. A CCM with auto-focus and 13Mpixel sensor will be added soon offering 30 frames per second and 64 degree FoV.

A fourth CCM, based on a 1.26Mpixel, 30 frames per second sensor has an integrated image flow processor, enabling vision functionality even for microcontroller platforms without additional hardware components.

System developers can write their own software drivers for the CCMs or make use of the driver produced by eInfochips, an Arrow company, which is due to be released at the end of Q1 2022.

Companies that wish to accelerate development times even deploy one of Arrow’s camera reference designs.

Arrow Electronics says it guides innovation forward for over 180,000 leading technology manufacturers and service providers.

Universal building actuator has four multi-functional contacts

Tue, Jan 18, 2022

In buildings automated with KNX software, different actuator types are needed to control switchable and dimmable loads, motors and valves. Universal actuators offer flexibility in planning and implementation and are suitable for switching devices such as electric lights or fans, as well as to control drives for blinds, shutters, awnings or windows.

Building control specialist, Elsner Elektronik has introduced the KNX S2-B6-AP with four multi-functional contacts. Each can be used individually to switch loads. The maximum switching load / switching current is limited to 8A although the contacts can also be used in pairs to control 230V drives.

The application software determines whether individual contacts or a drive channel is configured for each contact pair. The universal actuator then provides the appropriate settings. For the switching function, for example, these might be switching delays or a staircase lighting timer. To provide shade, queries regarding safety around locks, movement restrictions and priorities of commands are set first. Then the sunshade automation, including slat tracking, is adjusted. For windows, there is an automatic ventilation system to keep the temperature and humidity optimal. Movement positions for different scenarios can also be set.

The actuator also has six binary inputs. They are intended, for example, for local pushbuttons for manual operation of a shading system. In the pushbutton configuration, the input and output are directly connected in the actuator. When configured as a bus pushbutton, the input signal is sent to the bus as a communication object. Each input can then be set up as a (toggle) switch, for controlling drives or scenes, for dimming, as an 8-bit, temperature or brightness value transmitter. Alternatively, two of the inputs can be used for zero position sensors.

The actuator is designed to be surface mounted. Control LEDs and pushbuttons are visible under the transparent housing cover. The actuator can be tested during commissioning to ensure it reacts to commands.
