We supply an extensive range of switches for a variety of markets and applications.
These include:
Push Button switches
Piezo switches
Vandal Resistant switches
Toggle switches
Slide switches
Micro switches
Rocker switches
Safety switches
Limit switches
Rotary switches

Schurter Industrial Automation - Reliable Components and HMI

Image

Reliable Systems Thanks to Schurter Components and HMI for Industrial Automation

Regardless of the industry, modern electronic systems place high demands on even the smallest components. Stability, durability and absolute reliability are basic requirements to ensure that processes run safely and economically.

Schurter automamtion hmi1

In automated systems in particular, a single fault-prone component can halt entire production processes. It is therefore worth taking a close look when selecting electronic components and HMI solutions.

Schurter offers robust, industry-compliant components that have been specially developed for demanding applications – with a focus on quality, functionality and durability. Industrial automation leverages machines, sensors, control systems, and software to enhance efficiency, precision, and productivity in industrial processes.

Schhurter products contribute to this by providing reliable power supply, robust protection, and seamless connectivity, ensuring smooth and uninterrupted operation. By minimizing manual interventions and optimizing production workflows, Schurter helps manufacturers achieve higher performance, increased uptime, and improved operational safety.

Below are some key aspects of this application:

Electronic Switch with IO-Link Interface
With the MSS-IO, Schurter is entering the field of bidirectional communication via switches in industrial automation. The MSS-IO is based on the successful SCHURTER MSS electronic switch, which has been expanded to include an IO-Link module.

Energy Harvesting for Wireless Sensors
Modern automated production equipment relies on numerous cables for power and data transmission. But cabling takes up valuable space, reduces accessibility, and is sometimes the most failure-prone part of a machine. This is where compact and powerful prismatic supercapacitors come into play.

By enabling sensors to operate independently of a fixed power supply, supercapacitors help reduce wiring complexity. A small energy source—such as a solar cell or a kinematic energy harvester—generates low levels of power, which are insufficient for directly operating the sensor and its control IoT module. Instead, this energy is stored in the supercapacitor. When needed, the supercap releases high-power pulses, providing enough energy for the sensor to take a measurement and for the IoT module to transmit data via Wi-Fi.

Particularily Slim: FPAC Rail EMC Filters for Machine Control Units
Space is almost always at a premium in control cabinets for industrial applications. SCHURTER addresses this problem with a complete new filter design that is just 44 mm in width. The new, single-stage filter series is constructed with a printed circuit board in a plastic housing. It has screw terminals for the three phases and a terminal on the metal base plate for the earth connection.

The New Schurter 6080 With Cordset
Protection against dirt particles and moisture is becoming increasingly important. With the product type 6080 and the associated V-Lock power cable, SCHURTER is launching an IP54 device connection that also meets very high demands.

ETA 3120-N Thermal Circuit Breaker

Image

Reliable. Compact. Cost-Effective.

Eta 3120 small2

The 3120 thermal circuit breaker/switch combination unites overcurrent protection and the function of an ON/OFF switch within a single component. The trip element is a thermal bimetal. Type 3120 is ideally suited for overload protection of motors, pumps, transformers and cables. After tripping, it can reliably, easily and quickly be reset. The positively trip-free mechanism ensures reliable disconnection of the circuit even with the actuator blocked.

Benefits:

  • Dual Functionality: Combines a circuit breaker and switch in a single compact unit.
  • High-Performance Bimetal Technology: Responds to overloads based on current intensity and ambient temperature for precise protection.
  • Quick Reset: Eliminates downtime and the hassle of replacing fuses.
  • Cost-Effective Design: Streamlines installation, wiring, and logistics—ideal for mass production or modular systems.

Versions Upon Request:

  • ON/OFF Switch without overcurrent protection according to the relevant standard for switches for appliances IEC/EN 61058
  • Thermal-Magnetic version for an additional short circuit protection
Eta 3120

Typical Applications:

  • Medical and Laboratory Equipment
  • Apparatus and Machine Construction
  • Professional Tools
  • Household and Garden Appliances
  • Offices Machines
  • Audio Equipment
  • Machine Tools

Key Features:

  • Single or double pole thermal circuit breaker/switch combination
  • Voltage ratings: AC 240 V, DC 50 V
  • Current rating range: 0.1 … 20 A (up to 30 A upon request)
  • Optional: push-in terminals for easy and quick wiring with a long-term stability
  • Functional extension options with add-on modules for low voltage release, auxiliary contact function or remote trip
