With Power-over-Ethernet the devices can be placed flexibly inside & outside the building regardless of a socket. Through this technology power can be supplied to the IP-enabled devices via the network cable. In complex wireless LAN installations & in building surveillance with IP cameras the Po E-components drastically reduce the installation costs, since no power line need be laid to the place of installation.
The switch detects automatically, whether a Po E-device is connected & which voltage does it need. Hereby, the maximum possible Po E power of 15.4 watt is available at every port. If a device is connected, which does not have a Po E support, the switch detects this too & no voltage is applied, so that the device is protected against damage. The Po E-switch has a robust metallic casing & can also be installed 48.3 cm (19"), so that it finds place in every conventional server rack. The eight RJ45 network ports automatically detect the transfer rates of the connected devices (10 or 100 Mbit/s). The full & half-duplex operation makes available maximum 200 MBit/s per port.
Through the management functions the Po E switch becomes the absolute professional device for modern network control. The management features include quality of service, VLAN segmentation (IEEE802.1Q VLAN tagging & port-based VLAN) & spanning tree, as well as extensive monitoring functions. The switch is thus optimally prepared for modern forms of communication like Voice over IP.

The more detailed a model, the more functions would one like to control. In case of illumination, cranes, windlasses, . . a lot of switch channels are needed very quickly. In order to fulfill the requirement of as many channels as possible, favourable procurement & resource-protecting handling with the Prop-channels, the switch channel decoder 16 + 6 was developed. With 1 Prop-channel 16 switching functions can be controlled with 2 A steady current. No encoder module is needed in the transmitter. The control is done directly by means of a joystick. Depending upon the operation the channels are available as on/off or also as memory function. Via a second prop-channel 6 more auxiliary channels can be controlled, which, however, possess only one control output, the combination with the sound-synchronous model is suitable here. ...

This junction box features a lid switch to warn against tampering of the system. This will immediately inform the central alarm unit of attempted sabotage. The junction box has 16 twin solder tags. Intended for surface mounting (suitable for a 55 mm switch holder box). All these junction boxes have VDS Class C approval. ...

The handle covers developed according to the latest knowledge, with 3 different gripping zones, give an optimum position to the pliers in the hand & thus enable a fatigue-free working. A holding ring is integrated in the cover for securing the tools while working on roofs, scaffolds & in high buildings. This not only helps in preventing the tool from falling out, but in future can also take up other jobs. ...
