ATEX Pneumatic components is a serious option to consider
The original design of Darth Vader's armor didn't originally include a helmet. But today Darth Vader's helmet, combining a full-face breathing mask with a samurai helmet, is one of the most iconic designs of space fantasy cinema. Breathing under stress is a critical feature of the helmet.
"The respirator function is much more than a scuba tank regulator" observed a DesignLab quality engineer. We recommend highly reliable ATEX components to control the respirator valves in explosive environments.

The IoT Gateway allows virtually any sensor to be monitored from anywhere with a Cellular connection.
As standard the IoT Gateway accepts inputs from the following:
• Up to 128 IWT Industrial Wireless Transmitters
• 4 off 4-20 mA or 0-10 V analog inputs
• 8 off digital inputs
• 4 off Relay outputs
• Any Modbus enabled instrument over RS-232, RS-485, or Ethernet
• I²C and/or SPI sensors (may need custom software)
• The IoT Gateway uses the MQTT protocol to send this data to remote servers using the built-in 2G/3G or 4G modem.
As Standard, the remote server runs a standard web-based SCADA project which allows monitoring of the inputs and logged data from any device with an Cellular connection.
This package can also provide automated custom reports and email or SMS alarm messages.
Other options include a built-in GPS module and a local display showing input values and set-up information.
Features:
• Easy, real-time monitoring of remote assets via the internet
• Includes 2G/3G/4G modem and digital communications ports for data acquisition
• Input types include Analog/digital I/O, IWT wireless sensors, and I²C /SPi sensors
• Can be battery or 12-24 V dc powered

FMBD EP 3-Phase Mains Filter
• Compact design with minimal footprint
• Double-stage filter with high attenuation
• Variants for high voltage applications
• Wide temperature range
Schurter introduces the FMBD EP double-stage flagship filter family for 3 phases with neutral line systems. Thanks to its particularly compact dimensions and high performance, the new filter series is ideally suited for the tight space conditions in today's machine and industrial plant construction. Versions with high nominal voltages make a wide field of applications possible.
Space is a scarce commodity in control cabinets for industrial applications in the 3-phase range. Schurter has addressed this problem with another completely new filter design, which is much more compact than previous generations. The new, almost cuboidal design makes optimum use of the space in the housing. Thanks to a double-stage filter and the use of the highest quality components (generously dimensioned film capacitors, chokes with highly permeable cores), the new development shines with exceptional broadband filter attenuation.
Suitable for High EMC Emissions
The double-stage filter family is therefore also appropriate for applications with particularly high EMC emissions, as is frequently encountered in industry. Typical applications include machines and systems for automatic production, motor drives and industrial plant machinery. These powerful filters are also the first choice for modern frequency inverters for motor control.
Mounting
The FMBD EP series features screw terminals for absolutely safe wiring. Thanks to the metal flange, an excellent earth connection is ensured when screwed to the chassis.
Wide Temperature and Voltage Range
The standard types can be used over a wide temperature range from -40 °C to 100 °C. The filters are designed for currents from 16 A to 230 A at an ambient temperature of 50 °C. They have both ENEC and cURus approval for applications up to 520 VAC and ENEC and UR approval for applications up to 760 VAC.
Leakage Current
The standard versions are designed for industrial applications with leakage currents of <9.4 mA. Special variants with leakage currents of <2.5 mA are available for critical applications.
The completely redesigned FMBD EP models are the ideal replacement for all types of SCHURTER FMBD and FMBD NEO filters. They offer at least identical performance with significantly reduced dimensions and weight.

Bus Stop Buttons Are Now Wireless & Battery-Free Using Energy Harvesting Technology from ZF
Thanks to the wireless and battery-free switch technology from ZF, there are various possible application fields to increase connectivity, flexibility, and convenience. Bus stop buttons are another smart application integrating the inductive RF generator module. The target is to avoid cabling (up to 100m) and expensive maintenance work caused by cable breaks in buses. The energy harvesting switch guarantees design freedom and reduces maintenance work to a minimum as it has a lifetime of over 1,000,000 switching cycles.
The energy harvesting switch can be integrated directly into the plastic housing of the stop request buttons in buses. The compact design (20.1 x 7.3 x 14.3 mm) makes it easy to integrate. In addition, the ZF radio switch generates a voltage pulse by mechanical actuation as it relies on the inductive principle. Therefore, RF commands can be reliably sent via commercially available radio protocols such as EnOcean3.0 at a frequency band of 868MHz. In this case there is no risk of RF interference with Bluetooth devices which operate at a 2.4 GHz frequency range. Altogether, the radio switch is completely free of batteries or cabling, allows a reliable RF transmission and offers a high degree of flexibility when it comes to mounting in buses.
Each RF switch has a unique ID and can be programmed individually. This means that each stop request button can be assigned to a specific command group, such as opening doors at the front, back, or initiating measures for wheelchair users. The buttons are paired to the central receiver unit, which is again connected to the electrical bus system. Depending on the received command, the receiver triggers a visual or acoustic signal to give the bus driver appropriate instructions.
