Safety switch designed for hygienic
environments
The BZ 16 safety sensor has no openings and no 'dead zones' which could act as dirt traps and is thus extremely well suited to applications with strict hygiene requirements.
Smooth surfaces, no openings and no 'dead zones' which could act as dirt traps: the BZ 16 safety sensor meets all these criteria and is thus extremely well suited to applications with strict hygiene requirements For machines within the meat production industry, as well as other food production areas, it therefore represents a viable alternative to conventional electromechanical safety switches

Position switches use wireless data transmission
At Drives and Controls 2006 Steute showed a range of products which underline the company's three main areas of technical expertise: industrial control, explosion protection and medical foot controls.
Position switches meet safety and Ex standards
Any mechanical engineer using position switches is familiar with DIN EN 50 047.
In these areas entire machines are often cleaned with high-pressure water hoses.
steute has therefore made an intense study of the detailed construction of this device and overhauled both its enclosure and its seals.
This new version of the BZ 16 can now be exposed to high-pressure hoses without a second thought: water cannot even penetrate to the interior of the sensor at a pressure of 100 bar and/or temperature of 80 C.
The BZ 16 IP69K - as we have called this new version of the BZ 16 - can thus be used in areas with very strict hygiene requirements, but is also suited to applications requiring very high safety levels.
The switch communicates with its actuator by employing two different types of signal transmission.
This guarantees the redundancy required for safeguarding protective doors in crucial areas.
In addition, the switch monitors its safety-related functions automatically.
With regard to machine safety standards, this means: the BZ 16 is also suited to applications in control category 4 according to EN 954-1 or PDF-M according to 60947-5-3.
As well as the BZ16, steute will also be presenting other safety sensors from its EEx RC Si series at the Hanover Fair.
These high-safety switching devices have been developed for use in explosive endangered areas, but due to their extremely robust construction they are also attractive for use in other fields requiring long-life functioning in adverse ambient conditions.
These sensors are not only thoroughly encapsulated, but are also extremely shock-resistant and able to withstand other mechanical impacts.
