Suitable for all currents

The electromechanical magnetic switch MAK-1513-LEX-7 from Bernstein is a reed switch designed for use in industrial applications. It is based on reed contacts, which change their electrical behavior when a control magnet approaches. These switches are suitable for all types of current, including alternating and direct current. The switch is designed as a changeover switch, meaning it can switch between two switching states depending on the position of the magnet. It is commonly used in systems where contactless but reliable actuation is required, such as in automation systems, machine controls, or safety systems.

Applications

The MAK-1513-LEX-7 is intended for use in industrial environments where mechanical actuation via a magnet is required. Typical application areas include monitoring movements, positions, or states in machines and systems. It can, for example, be used to detect the opening or closing of doors, covers, or containers. Due to its contactless actuation, it is particularly suitable for applications where mechanical wear should be avoided.

Functions and Equipment in Detail

The switch operates based on reed contacts activated by a magnetic field. When a control magnet approaches, the electrical state of the contact changes — in this case, it is a changeover switch that switches between two positions. The all-current-capable design allows use in various electrical systems, regardless of current type. The construction is designed to ensure high operational reliability and long service life, as no mechanical movements occur in the contact area.

Technology Explained Simply

Reed contacts consist of two springy metal strips enclosed in a glass tube under vacuum or inert gas. When a magnet is brought close to the tube, the contacts are drawn together by magnetic attraction and close the electrical circuit. When the magnet is removed, the contacts open again. In the case of the MAK-1513-LEX-7, it is a changeover switch that switches between two switching states depending on whether the magnet is close or not. This technology enables a reliable, wear-free switching function, which is particularly in demand in industrial applications.

Compatibility and Accessories

The exact shape and size of the magnet must be adapted to the application to ensure secure actuation.

Mounting and Installation

Mounting depends on the specific application. The switch can be integrated into suitable enclosures or assemblies, with positioning ensuring that the control magnet can reliably reach the reed contact. Electrical connections are made via the terminal clamps, designed for connection to wires or controls.

The indication “1 Reed” refers to the number of reed contacts integrated into the switch.

Advantages in Operation

The MAK-1513-LEX-7 offers a wear-free switching function, as no mechanical contacts are moved during operation. Actuation is contactless via a magnet, which increases service life and improves reliability in continuously operated systems. The all-current-capable design enables flexible use in various electrical systems. The simple mounting and integration into existing systems make the switch a practical solution for many industrial applications.
