## Long description

The Siemens 3SE6604-2BA is a high-performance magnetic switching element engineered for critical safety applications in industrial environments. This component features a 2NC (normally closed) contact configuration, providing reliable and secure monitoring for protective doors, covers, and guard fences. Designed for seamless integration into safety systems, this contactless device ensures consistent performance even in demanding technical settings.
Advantages
This magnetic switching element offers a compact design that is ideal for installations where space is at a premium. Its contactless operation ensures a long service life by eliminating mechanical wear, while the coded technology provides high resistance to manipulation. The device is built to meet rigorous safety standards, supporting high-level safety requirements such as PL e or SIL 3, which makes it a dependable choice for protecting personnel and machinery in automated systems.
Suitable for
Monitoring of safety guard fences
Secure locking of protective covers
Position monitoring of industrial doors
Safety-critical industrial automation systems
When it may not be suitable
This device is not intended for use in environments where strong external magnetic fields could interfere with the sensor's operation. It is also not suitable for applications requiring high-current switching, as it is designed specifically for signal monitoring within safety circuits.
Key specifications
Contact configuration: 2 NC (normally closed)
Dimensions: 25 x 88 mm
Connection type: Integrated 3 m LIYY cable (4 x 0.25 mm²)
Compatibility: Designed for use with 3SE6704-2BA or 3SE6701-2BA solenoids
Technology: Contactless magnetic operation
How to use
The switching element should be mounted in conjunction with a compatible magnetic solenoid. Ensure the sensor is aligned correctly with the actuator to maintain the specified operating distance. The integrated cable should be routed through protected conduits to prevent mechanical damage. Once installed, the 2NC contacts should be wired into the safety control circuit according to the system's wiring diagram to ensure the safety function is correctly triggered when the guard is opened.
What to consider before purchase
Verify compatibility with your existing safety controller
Ensure the required operating distance matches your specific mounting setup
Check if the 3-meter cable length is sufficient for your installation layout
Confirm that the solenoid actuator is available or purchased separately
Usage recommendations: Always perform a functional safety test after installation to ensure the switching element correctly triggers the safety stop when the guard is opened. Regularly inspect the sensor for physical damage and ensure the mounting remains secure to prevent misalignment.
