What are Terminals and Terminal blocks?

SNK Terminals are a type of industrial control terminal that is used in industrial automation, process control, and other applications. These terminals are designed to provide a secure and reliable connection between the user and the machine. They are typically used to control machinery, monitor production processes, and manage data. SNK Terminals are available in a wide range of sizes and configurations, allowing them to be used for many different types of applications.

Modular terminals are components that can be used to connect two or more devices together in a network. They are typically used to connect computers, servers, routers, switches, and other network devices. Modular terminals are often referred to as RJ-45 connectors because they use an 8-pin RJ-45 connector.

A terminal block is a type of electrical connector used to connect two or more wires together. It typically consists of a metal or plastic housing containing multiple terminals, which are the points at which the wires are connected. Terminal blocks are commonly used in industrial and commercial applications to provide a secure connection between electrical circuits.

Schurter EKO: High-Performance HV Fuses

EKO: High-Performance HV Fuses for Industrial and Energy Applications

Rated voltage: 1000 VDC (1250 VAC available for
selected series)
Rated currents: 50 – 1100 A
Breaking capacity: 50 kA DC (100 kA AC for
selected series)
Characteristic HV Fuse Mounting Flush End,
DIN-Rail, US Style Bolted Tag, Bolt-on

The EKO series is engineered for demanding high-voltage environments, offering protection up to 1000 VDC (and 1250 VAC for selected models) and current ratings from 50 to 1100 A. With a breaking capacity of up to 50 kA DC, these square-body fuses deliver safety and reliability.

Designed for robust performance, the EKO series withstands mechanical vibration, shock, chemical exposure, and extreme temperatures from -40 °C to +125 °C. Its ceramic housing and tin-plated copper alloy terminals ensure durability and stable electrical characteristics even under harsh conditions.

Choose from Flush End, DIN-Rail, US Style Bolted Tag or Bolt-on to simplify integration into diverse systems. Optional indicators and microswitches enable easy status monitoring.

Schurter MSM II-Switch with Common Anode Control of RGB LED

MSM II-Switch with common anode control of the RGB LED

Optimised for industrial control architectures
Usual SCHURTER Metal Line quality
Protection class IP67

The well-established MSM II mechanical switch family is growing. With the MSM II (Common Anode), Schurter is introducing a variant that uses a common anode to control the RGB LED illumination. This combines the familiar robust mechanics with visualization technology for clear feedback, easy integration, and maximum reliability in control and operating solutions.

RGB LEDs can be controlled either via a common anode (+) or a common cathode (–). While with common cathode all negative poles are connected together and the colors are controlled individually via the positive pole, the common anode variant does the opposite: all positive poles are connected, and the color channels are switched separately to ground.

The MSM II (common anode) offers maximum compatibility with modern driver ICs, PLC outputs, and microcontrollers, which are predominantly designed for common anode control. This facilitates integration thanks to a simple signal structure and reduced wiring requirements.

The combination of tactile precision, IP67 protection, robust design, and flexible RGB signaling makes the MSM II switch ideal for a wide range of applications, particularly in industrial control units such as control panels, production facilities, building automation, and access solutions.
