Enclosure heaters on display.

STEGO Elektrotechnik will be presenting its enclosure heater with a novel loop design at this year's SPS in Nuremberg (D).* STEGO's showcase for the return of the SPS trade fair also features an update to the KTO/KTS control cabinet thermostats and new smart sensors.

Their LPS and LTS product series give an update to its PTC-based convection heaters with capacities of between 10 and 150 W. The cooler bodies in the new loop profile design absorb the heating capacity of the PTC elements better and ensure a higher stability of the device against vibration. This means the LTS series of heaters is able to comply with the standards for mobile railway applications (DIN EN 60068-2-27:2010-02 and DIN EN 60068-2:64:2009-04). STEGO consistently uses push-in terminals for electrical contacts in the LPS and LTS series. Easily accessible on the front of the devices, the push-in terminals provide time savings of up to 50% by allowing for tool-free insertion of the cables. The terminals exert constant pressure on the supply lines, which provides added security even when transporting pre-assembled control cabinets, for example. You therefore do not need to worry about the connecting cables coming loose and resulting short circuits.

New editions of their KTO/KTS fine-tune STEGO's mechanical thermostats to better meet the needs of control cabinet construction in practice. The thermostats are designed as two-point regulators with a thermobimetal sensor element. The KTO 111 is a contact breaker (NC) for controlling heaters. The KTS 111 is a contact maker (NO) for controlling filter fans, heat exchangers, coolers and switching signal devices. Push-in terminals are used for making electrical contact. They ensure that connecting the power cables is safe, tool-free and fast. Users can expect a reduction in installation time of up to 50%. STEGO engineers have also optimized the housing design so that the thermostat now literally has more air. Larger air vents in the main unit, which tapers towards the back,

The newly developed DSS 015 Distance Smart Sensor (right) measures the distance of objects using the time of flight (ToF) of ultrasound waves. The DSS 015 Distance Smart Sensor is designed for monitoring distances or fill levels in industrial applications. The DSS 015 can even detect transparent objects such as glass, films and fluids. It is also unaffected by changing light conditions, and easy to connect to higher-level control systems (eg SPS) via its IO-Link interface.

STEGO is expanding its range of sensors for industrial applications that use IO-Link. Their SHC 071 Sensor Hub offers a cost-effective interface through which STEGO sensors can easily be connected to IO-Link installations. The SHC 071 Sensor Hub records measuring data on the process level from up to four external, non-IO-Link-capable STEGO sensors and transmits the data via the IO-Link Master to higher-level control units such as Edge computers, the cloud , SPS control etc. The Sensor Hub can be used to connect up to four external STEGO sensors while using only one port on the IO-Link Master, saving the IO-Link Master's connection capacity. The number of connected sensors and the allocation of sockets can be freely chosen by the user. Sensors from the SEN 073 series are available for the Sensor Hub. The sensors are pre-calibrated and are easy to connect to the Sensor Hub using a plug. Clustering IO-Link functionality in the Sensor Hub allows the sensors to take on a compact form factor. Sensors in the SEN 073 series can be used to record data in the following fields of application: temperature and relative humidity, temperature and absolute air pressure, visible light, illuminance and VOC.
