At SPS, Stego presents a number of innovations: for example, switch cabinet heater in the new loop design and newly launched bimetal thermostats. In addition, Stego presents an increasingly expanded sensor portfolio.

Heat sinks in the new loop profile design better absorb the heat release from the PTC elements and ensure a constant bias that keeps the heating elements tight.

With the new LPS and LTS product series, climate specialist Stego has prescribed an update to its PTC-based convection heaters in the power range from 10 W to 150 W. They come in a new loop design. The heat sinks in the loop profile design absorb the heat release from the PTC elements better and ensure a constant bias which clamps the heating elements stably. The LTS series heaters comply with the standards for mobile railway applications (DIN EN 60068-2-27:2010-02 and DIN EN 60068-2:64:2009-04).

For electrical contact, Stego relies on push-in terminals. They are easily accessible on the front of the device and save up to 50 percent time by inserting the cables without tools. The terminals exert constant pressure on the supply lines, which also ensures safety when transporting fully assembled control cabinets. Loosening of the connecting wires and thus short-circuiting is impossible.

New bimetal thermostats

The bimetallic thermostats KTO / KTS have also been relaunched by Stego. The mechanical thermostats are adapted optimally to the needs of switch cabinet construction in practice. They are designed as two-point regulators with a thermal bimetallic sensing element. KTO 111 is an opener (NC) for controlling heaters. KTS 111 is a start switch (NO) for controlling filter fans, heat exchangers, cooling units or signaling devices.

Push-in terminals are used for electrical contact. They ensure a safe, tool-free and faster connection of the power supply cables. The manufacturer promises that users can expect assembly time to be reduced by up to 50 percent. The Stego engineers have also optimized the design of the house: The thermostat now literally gets more air. Enlarged air openings in the body, which taper towards the rear wall, ensure optimized air intake and thus improved response to temperature changes.

Expanded sensor portfolio

The newly developed Distance Smart Sensor DSS 015 determines the distance to objects using ultrasonic wave propagation time measurement (ToF – Time of Flight). A suitable application for the Distance Smart Sensor DSS 015 is distance or fill level monitoring in industrial applications.

The special feature: DSS 015 even detects transparent objects such as glass, foil or liquids. It is also insensitive to changing light conditions. It can be easily connected to higher-level control systems (e.g. PLC) via its IO-Link interface.

Stego is constantly expanding its range of sensors for industrial applications in the IO-Link environment. Also new, for example, is the Sensor Hub SHC 071. This is a cost-effective interface designed to easily integrate Stego sensors into IO-Link installations. According to Stego, the Sensor Hub SHC 071 collects measurement data from up to four external, non-IO-Link compatible Stego sensors at process level and transmits data via IO-Link masters to overall control devices such as edge computers, cloud, PLC control, etc.
