Energy harvester from ZF for windows and doors

Wed, Feb 28, 2024

Installed in applications for windows and doors, the Energy Harvester from ZF contribute to energy efficiency and building security. They monitor if a window is open or closed and prevent for example the waste of heating energy. By RF technology, the current status of a window will be reported to the building technology and when the window is open, the heating or air-condition will turn down. If a window or door has not been closed, this information can also be checked on a central unit. Thus, the effort for the guard duty of big commercial buildings will be reduced.

By each actuation of the ZF Energy Harvester, sufficient energy for the transmission of a RF protocol is generated. The connected radio electronics transfers the status information to a receiver unit. So, window handle, window latch or door lock inform with every opening and closing about the change of status.

The completely battery-free and wireless technology from ZF is free of maintenance and flexible in use. It can be realised with different RF protocols such as Bluetooth®, EnOcean or customer-specific RF protocols.

New 10A relays from Omron, with high dielectric strength and extended safety certification

Tue, Feb 13, 2024

Omron has extended its relay portfolio with the introduction of its G6RN-E, for heat pumps, smart building, factory automation and energy applications. The latest model provides current load to 10A, with extended dielectric strength to 6000VAC, high sensitivity with 220mW coil power consumption.

The new G6RN-E relays provide greater safety, conforming glow-wire test requirements for household and similar electrical appliances to IEC/EN60335-1 and conforming to explosion-proof certification IEC/EN60079-15. Fulfilling international safety standards for resistance to ignition. This makes them ideal to ensure the safety of air conditioning equipment such as air conditioners and heat pumps.

G6RN-E relays introduce a flux protection housing, offering 6000VAC dielectric voltage between coil and contact. Further features include a high insulation with an 8mm insulation distance, robust impulse withstand voltage of 10kV between coil and contacts, high sensitivity with 220mW coil power consumption, and ambient operating temperature of 85°C and the standard model conforms to UL, VDE standards. Conformity to recommended building and factory automation applications extend to heat pump controllers and inverters, as well as gas boilers, temperature controllers and PLC. Terminal arrangement and contact ratings are the same as existing Omron G6RL relays with same pin.

ZF launches a battery-free energy harvesting switch module.

Wed, Feb 07, 2024

ZF has announced a battery-free and wireless switch module which is based on ZF’s patented energy harvesting technology and the EnOcean protocol.

As a member of the EnOcean Alliance, ZF succeeded in fully certifying the switch module in accordance with the EnOcean RF standard which is especially designed for energy harvesting solutions.

The ZF switch module uses the RF frequency 868 MHz and operates energy self-sufficient i.e. batteries and wires are completely redundant. The energy for sending a RF protocol is generated by the actuation of a very compact inductive generator (20.1 x 7.3 x 14.3 mm).

The maintenance-free modules are compatible with various switch designs available on the market. As a wireless solution, these radio modules offer flexibility and design freedom in order to realise individual requirements.

Besides the switch module with EnOcean protocol, a module for KNX-RF is available in series production. Also customer-specific protocols are possible.

At Light+Building in Frankfurt from 3rd to 8th March 2024, ZF shows in hall 9.0, stand no. E21 various energy harvesting applications in the area of Smart Home & Smart Building.

New inertial GNSS smart antenna from Septentrio

Tue, Feb 06, 2024

Septentrio has announced AntaRx-Si3. This is the first GNSS/INS (Inertial Navigation System) Smart Antenna on the market in an ultra-rugged enclosure, designed for easy installation on machines such as agriculture robots. AntaRx-Si3 is the new member of the family of receivers leveraging FUSE+, which is designed to answer the need for position availability in tough industrial environments where GNSS signal reception may be temporarily compromised, such as under foliage. The IMU sensor in FUSE+ also improves positioning integrity and reliability, which is critical for autonomous systems.

“With AntaRx-Si3 you get a receiver delivering positioning information with a high level of availability and integrity, that you can install with minimal effort. This is especially beneficial for after-market upgrades. It also allows removal of this component at the end of the day to protect against theft or vandalism,” commented Danilo Sabbatini, Product Manager of GNSS/INS at Septentrio.

It is designed to be mounted outside on a machine for operation in harsh environments out in the field. Enclosed in an impact resistant polycarbonate IP69K housing it can handle high levels of shocks and vibrations. This multi-frequency receiver delivers Septentrio’s field proven RTK positioning down to the centimetre level. AntaRx-Si3 has a built-in 4G cell modem, so there is no need for additional modem integration to acquire high-accuracy corrections.

AntaRx-Si3 leverages Septentrio’s GNSS+ algorithms with advanced multipath mitigation, which allows uninterrupted operation in environments where satellite signals could be reflected off nearby machinery or high structures such as silos. It delivers positioning at a high update rate and low latency, which are critical for control loops in autonomous movement or rotation.
