Fig 3: RTY360LVEAX – RTY series sensors are used both in the automotive and industrial sector.
HIH-6000, HIH-7000 and HIH-8000 series of components. They are similar solutions designed to measure humidity and temperature simultaneously. The differences between these product series consist mainly in their tolerance ratings, so the higher the series, the lower the error tolerance range, even ±0.5°C for temperature and ±2% for humidity. They come with digital outputs and communicate via I2
C or SPI protocols
supported by most microcontrollers. Such components are used in creating industrial and consumer circuits, for IoT as an example. They operate with voltages ranging from 2.3 V DC to 5.5 V DC depending on the model.
Angular position sensors The RTY series includes fully insulated, durable angular position sensors operating within the 50° to 360° angle range, with the tolerance rating reaching even 180°. They are intended for industrial applications, like controlling valves, throttles and nozzle swing, and automotive applications, like detecting the position of pedals, linkages, control and suspension system components. Such features as their mechanical resistance and the IP67 degree of ingress protection makes them suitable for installation on boats and in heavy machinery, such as cranes. Their service life is estimated at ca. 15 million cycles. The RTY sensors are connected via standard 3-pin automotive connectors, such as AMP-0-0282087-1, in the EU or American version. Two of these pins include DC power supply inputs (4.5–5.5 V or 10–35 V), and the third one constitutes a voltage output. The mechanical assembly is possible thanks to the 6 mm diameter truncated axis. The components are protected against both electromagnetic interference and incorrect connection.

Their characteristic features include
precision and excellent durability, and their formats and
parameters simplify the implementation process.
NGC limit switches ”
Limit switches are not only used for machinery control such as CNC machine tools, or position detection of cranes and heads, as they are also commonly applied in production and warehouse management automation systems to count items on conveyor belts, or position workpieces properly. Note also that they are used as safety elements in public utility systems,
such as lifts, escalators, and automatic doors. Due to the significance of their role, it is always advisable to select limit switches of tried-and-tested quality, offered by trusted manufacturers.
The NGC limit switches come with silver- and gold-plated contacts (two or four pairs) withstanding 5 A or 10 A currents. Consequently, they can be used to directly interrupt power circuits up to 240 V AC, 250 V DC, depending on the model, but they will also work well as signalling components. Connections are made using pre-installed 1 m or 5 m cables. Their design is based on the MICRO SWITCHES with the NC + NO configurations, where a state change is followed by the opening of one contact pair and closing of the other contact pair, or 2xNC + 2xNO configurations. The TME product catalogue includes NGC components with diverse mechanical designs, such as with a pin, a pin with a steel roller located transversely or longitudinally in relation to the body, as well as elements fitted with a lever and terminated with a plastic roller.
