Safety Switch, Guard Lock
Protect personnel and equipment with safety switches and guardlocks. These devices ensure secure access control and emergency shutdown in industrial environments, supporting compliance with safety standards.
Safety switch
Safety switches of the SAFEMASTER STS series reliably protect accesses and safety doors or flaps on machines and systems and are suitable for safety applications up to Cat. 4 / PL e in accordance with EN ISO 13849-1 without fault exclusion. Electromechanical safety switches (type 2) with separate actuator are ideally suited for safeguarding safety guards that can be rotated, removed or moved sideways and only provide the required safety when closed.
When the safety guard is opened, dangerous movements must be switched off immediately and secured against restarting. The dangerous machine can only be restarted when the safety guard is closed. The very narrow and robust design of the safety switch also allows space-saving mounting on movable guard.

Guard lock, Solenoid interlock electromechanical
Solenoid interlocks of the SAFEMASTER STS family combine the functional principle and the advantages of electromechanical safety switches with a 2-channel guard locking function. Guard locking ensures that rotating, removable or laterally movable protective devices such as safety guards, hoods, protective grids remain closed as long as a dangerous condition or risk of injury to persons exists. This includes, for example, safety applications with overtravel movements of a machine or system in which, for example, high temperatures or pressure prevail.
However, solenoid interlocks are also used in process protection where opening of the safety guard is not desired, such as unauthorized interference in the production process. Electromechanical solenoid interlocks act together as a link between the higher-level control system (PLC) and safety relay devices such as standstill and speed monitoring or safety time relays. In addition, different coding levels, very high locking forces and extensive diagnostic options enable use in almost any safety-relevant application.

Key transfer
The basic principle of the key transfer system ensures that a machine or system is in a safe state before an access can be made. A further safety aspect is that a key is inserted either in a safety switch or can be used for opening a door lock. This property can be used to force a certain operating sequence, which can not be deviated from. As a result, a high safety level is achieved and a large number of different danger areas can be ensured.
SAFEMASTER STS - Individual modules
The modularity of the SAFEMASTER STS allows individual adaptions to the corresponding applications. By means of bayonet locks (see accessory) any number of units can be mounted of only a few basic modules. The function of the units are defined from the way and arrangement of the modules, whereby several unities form a system. The possible combinations of the composed unities determine the individual functions of the total system.
Command devices
The robust stainless steel option module expands the modular safety switch and key transfer system SAFEMASTER STS with variable command, indication, selection and emergency stop functions. This turns the system into a true "control centre" from where command functions, status displays, release signals, main and maintenance access points can be controlled. The option module is form-fitting and can be installed directly underneath safety switches or hold closed units thus enabling direct command execution at the access points for machines and systems. It can also be installed as a standalone command device. You too can benefit from the high degree of system flexibility.
Load isolator with interlock
Power Interlocking of the SAFEMASTER STS family enables the simple integration of a load-break switch into the safety switch and key transfer system. It enables the direct separation and safety-related interlocking of the power supply of machines and systems. The safety system thus reliably protects persons entering the hazardous area.
