Compact Terminals SCTSi Ethernet
Flexible, Fully Networked Vacuum Generation
Variety, optimization of production processes, and continuous energy and process control are the challenges of the future. In order to meet these demands, powerful, flexible and energy-efficient vacuum systems are required. The answer is our Compact Terminal SCTSi Ethernet, a compact unit of several vacuum generators for simultaneously and independently handling different parts with a single vacuum system.
The compact terminal SCTSi is sort of the masterpiece of our engineers, a compact and powerful unit for vacuum generation in automated systems. Now Schmalz has enhanced the Ethernet version of the terminal by adding new modules. Via an IO-Link master that can be integrated into the terminal, field devices can be connected via IO-Link and thus communicate directly with the PLC. Digital field devices such as sensors are integrated via digital input modules – without separate I/O modules. The terminal thus becomes the central control unit for vacuum gripping systems.
Direct communication with the system controller via Ethernet interface (EtherCat, EtherNet/IP or ProfiNet)
NFC interface allows diagnosis and parameterization via smartphone
Central compressed air and power supply for up to 16 ejectors minimizes hosing effort
Individually controllable vacuum circuits allow handling of different parts
Condition monitoring for predictive maintenance and increased plant efficiency
Your Individual Configuration
The compact terminals SCTSi offer the flexibility to design the handling process entirely according to your needs. Thanks to innovative configurators, our sales staff can create a custom-made solution for you in no time at all.
In addition to an offer for your individual product, you will also receive a CAD model.

Networking in Industry 4.0 Systems
- The Ethernet connection means that recorded data can be viewed and used all the way up to the control level, which allows for bidirectional parameterization and diagnostics in all conventional field-bus systems
- Condition monitoring increases system availability by providing detailed analyses of the system’s condition and early detection of faults
- Predictive maintenance improves the performance of gripping systems
- Energy monitoring optimizes the vacuum system's energy consumption

Automatic Air Saving Function
- Switches off the suction function once a safe vacuum value has been reached until the next cycle or until the vacuum falls below the safe vacuum value
- Various configuration values and air saving settings can be programmed separately for each ejector
- Reduction of compressed air consumption by up to 80 %

Integrated Electronic Sub-Bus System
- Electronic control can be implemented with just a single cable
- Comprehensive data communication via Ethernet and near-field communication (NFC)
- All ejectors can be separately programmed and controlled

Eco-Nozzle Technology
