unit and halved the overall footprint size of their units by installing ABB HVAC drives, ACH580. The variable speed drives’ (VSDs) integrated control functions remove the need for external components, which saves space and reduces installation time.
The drives also improve the reliability and energy efficiency of Air Handlers’
equipment by providing the correct air flow via regulated fan motor speed. VSDs adapt their speed to the actual requirements of a motor at any given time. In this way, up to 50 percent energy is expected to be saved.

CamdenBoss’ new Room Sensor Enclosures aid in the emergence of new electronics systems
T
his year we have unprecedented circumstances that have not only changed the electronics world, but presented new issues.
With these new issues comes new opportunities and design solutions. Enclosures such as the CamdenBoss Room Sensor Enclosures are
helping with these new trends, offering a universal, compact solution with ideal features for sensor applications. These enclosures can be used for a wide variety of electronic devices such as air quality, movement (door entry and exit), heat and even to measure distance between two people.
Additional sizes have been added to the Room Sensor Enclosure range and are available in external dimensions:
74x74x25.5mm (Size 2) and 51x51x25.5mm (Size 3). These sit alongside the existing 86x86x25.5mm (Size 1). All the sizes are available as a vented or solid option and offered in three standard colours: white, black or grey.

Schmersal produces access control systems to support retailers during coronavirus crisis T
he Schmersal Group is helping retailers and other companies to cope with the effects of
the coronavirus (Covid-19) pandemic. The company has developed a digital access control system that makes it easier to comply with coronavirus regulations in public spaces without considerable staff expenditure.
The distancing rule is the order of the day in
these times of coronavirus, and to maintain safe distances, access management is absolutely necessary. The ‘Schmersal Human Counter’ (SHCIO-20) is an intuitive traffic-light system with integrated counter that automatically counts the number of visitors entering a building. As soon as a maximum number of visitors has entered, a signal tone is sounded to indicate that the person who entered the building last must leave. In addition, the system also uses traffic-light colours to indicate access or no access, with green meaning ‘please enter’ and red meaning ‘please wait’.
The system has already undergone several
weeks of testing at a retailer and is available for delivery immediately. The ‘Schmersal Human Counter’ could also come in useful in places such as fitness studios, doctor’s practices, restaurants and other public institutions.
The key elements of the system are an
indicator light (green, yellow, red) with buzzer and a programmable safety relay module from the PROTECT SRB-E series, produced at the Schmersal Group’s Wettenberg site. This module is normally used to monitor safety switchgear and achieves the maximum safety level in machine safety.
38 JULY/AUGUST 2020 | DESIGN SOLUTIONS The traffic-light system is quick and easy to
install, requiring just a conventional 230 V socket; the counter also needs to be set. The system, capable of counting up to twenty people, comprises entirely industry-tested components. For user-friendly operation, the system incorporates command devices from the Schmersal N range, which are designed for maximum hygiene and easy cleaning.
‘Many businesses have developed creative
emergency solutions for access management, but they often require considerable staffing or even raise the risk of contagion,’ explains Ulrich Bernhardt, Sales Manager for Control Systems at the Schmersal Group. ‘By contrast, the Schmersal Human Counter is a simple system that can requires very little investment and few staff. We have put our cumulative experience in safety systems into the development of the system. For decades, Schmersal has been working to ensure that people are protected from health hazards in their working environment.’
