The switches can be adjusted horizontally and vertically, with specific angles provided. They can switch to the right, left, or both sides. Installation notes emphasize the need for positively mounted actuating elements according to EN 1088.
The document includes detailed ordering tables for different series, roller materials, switching elements, and function displays. Examples of ordering codes are provided for clarity.
The document includes diagrams for travel and contact positions, emphasizing the need to replace damaged or worn safety switches as a unit. It also provides notes on maintaining positively driven travel dimensions.
The document details the specifications of EUCHNER multiple limit switches, focusing on the precision and durability of the components. The operating point accuracy varies depending on the plunger type, with a maximum approach speed of 120 m/min. The switches are made with high-quality materials like acrylonitrile-butadiene rubber (NBR) for seals, ensuring resistance to oils, greases, and other fluids.
Plungers are made of stainless steel and are designed for high accuracy and reliability. There are different types of actuating systems, including telescopic and rigid plungers, each suited for specific applications. The document also describes the travel and movement characteristics of the plungers.
The document distinguishes between snap-action and slow-action switching elements, explaining their operation and applications. Positively driven contacts are emphasized for safety applications, ensuring reliable separation even in case of contact welding.

Position Switches EUCHNER Positively driven contacts Positively driven contacts are used in some switching elements. These are special switching contacts that are designed to ensure the switching contacts are always reliably separated. Even if contacts are welded together, the connection is opened by the actuating force. It is a common feature of all safety switching elements that at least one switching contact is designed as a positively driven contact. Often two positively driven contacts are employed to increase safety using the principle of duplicated design (redundancy). This dual-channel...
