Littelfuse is at the forefront of this growing market, creating solutions that are ideally suited for commercial automation applications.
Smart Locks
Smart-lock technology ensures access to specific rooms or buildings only to those who should have it. With a wireless interface, users can access the lock either locally via smartphones or remotely via a network-attached PC.

Door and Window Sensing
Open doors or windows not only present potential security concerns but also impact energy efficiency, causing heating and cooling systems to needlessly run. With door and window position-sensing systems, the status of doors and windows can be remotely monitored and users can be alerted when a door is left ajar or a window opened.

Outdoor and Wireless Security Cameras
Advancements in wireless technology have also made wireless security cameras a more reliable standard, even with high-definition video. Littelfuse technology helps keep these security-critical devices protected.

USB Outlets
Modern businesses are run on the go — and that means smartphones and tablets are a necessity. As such, many commercial spaces are incorporating USB outlets into their design. USB outlets combine traditional AC wall outlets with USB charging ports, offering visitors and employees an easy and convenient way to charge and power USB devices. Some USB outlets even offer battery backup, helping ensure that employees can charge their devices even in an instance of a power failure.

Smart-Lighting Solutions
Smart lighting is a massive trend in commercial design — from office buildings to airports to parks to stadiums. Utilizing LEDs that offer significant power savings over traditional light bulbs, presence sensing to reduce unnecessary energy consumption, and networked systems to decrease maintenance costs, today’s lighting solutions are a significant point of savings in commercial applications.

GFCI/AFCI Receptacles
Not only are ground-fault circuit-interrupter outlets required by building code, they
are critical for protecting sensitive equipment and expensive computers. When a GFCI/AFCI outlet detects a suspected ground fault or arc, it interrupts power, helping keep devices safe and preventing potentially hazardous overcurrent situations.

Intelligent Outlets
Intelligent outlets work with the building’s network to enable remote control
of devices plugged into the outlet via smartphone. These enable workers to remotely control any device plugged into the outlet.

Electronic Dimmers
Electronic dimmers control light levels using a solid-state MOSFET and are often internet-enabled. Electronic dimmers are helping commercial spaces save energy and reduce unnecessary lighting in rooms where no workers are present.

Electric, Gas, and Water Meters
Smart energy management starts at the source — in this case, electric, gas, and water meters. Smart meters are enabling a new standard of advanced energy management. By sending meter readings to the power, gas, or water utility wirelessly, utility companies can better understand consumption habits and plan accordingly. Smart meters can also enable building supervisors to better understand their energy, water, and gas consumption and find areas for improvement.

PIR Motion Detection
Passive infrared motion detectors have become the go-to standard for motion detection systems, not only used for security monitoring but also as occupancy detectors. With an ideal combination of performance and affordability, PIR motion detectors are ideally suited for applications where reliability and budget are a top concern.

Smart Thermostats
While smart thermostats have quickly become commonplace in homes, businesses of all kinds are employing this technology to reap massive benefits and energy savings. These internet-capable devices have not only enabled easy remote control of a building’s temperature but are leveraging artificial intelligence and machine learning to understand temperature-setting trends
and better optimize HVAC systems for peak energy performance.

HVAC Systems
If smart thermostats are the front end of temperature efficiency for building comfort, the HVAC systems themselves are the back end, where commercial buildings realize massive savings in energy. For both the HVAC control units and drive systems, Littelfuse products are helping to ensure that these systems operate reliably and safely and deliver peak performance.

Elevator and Escalator Systems
For decades, transport inside buildings remained relatively unchanged. Today, however, these systems are seeing a facelift in light of technological advances. Elevator and escalator drive systems are becoming smarter and more efficient, while elevator cabin solutions are making it easier for occupants to find their way around and give appropriate users access to the correct floors.
