In Löhne approx. 180 employees meticulously develop and manufacture safe switchgear for demanding and critical applications. Devices include safety and position switches, as well as switchgear for extreme industrial applications. Another business field is responsible for the manufacture of switchgear for explosive atmospheres – Ex position switches, Ex pull-wire switches, Ex safety switches and solenoid interlock systems, as well as Ex magnetic sensors. steute also provides a wide range of switching devices for medical equipment. All three business areas – control technology, explosion protection and medical equipment – make good use of high-performance and innovative radio technologies.
The best solution in explosive areas Wireless and energy-autarkic switching devices possess a high potential to optimize the entire machinery and plant industry, e.g. more flexible constructions for movable or autarkic plant parts, as well as easier, more favourable installations, especially upgrades.
In potentially explosive atmospheres, radio switchgear devices offer particular advantages. For every wired connection is a potential risk. The steute business field Explosion Protection has developed a new range of switchgear for this purpose: the devices transmit signals wirelessly and generate the necessary energy themselves, according to the »Energy Harvesting« principle. This means: no cable, no connectors, no battery!
Energy-autarkic switchgear devices use an electrodynamic energy generator as a »mini power station«. The latter converts the kinetic energy released by actuating the plunger into electrical energy - an elegant principle. This is facilitated via magnetic induction of a permanent magnet within a coil.
The switches are able to transmit from inside a potentially explosive atmosphere, meaning that conventional receivers can be applied. Thus the energy-autarkic switching technology reduces the explosion risk and at the same time lowers expenses. The entire range – command devices, position switches, pull-wire switches and foot switches – is ATEX approved for application in gas Ex zone 1 and 2, as well as in dust Ex zones 21 and 22.
