Phoenix Contact 1692844 SACB-8/16-M23 Sensor/Actuator Box content_copy

The Phoenix Contact Sensor/Aktor Box SACB-8/16-M23 (manufacturer number 1692844) is a distribution module for the decentralized connection of sensors and actuators in industrial automation systems. The device serves as an interface between a main cable and multiple end devices and enables structured, reliable cabling in production environments. The box is designed for use in standard applications and offers a clear, modular structure for integration into existing bus systems.

Applications

The SACB-8/16-M23 is suitable for applications in industrial automation, particularly in environments where high mechanical load capacity and a secure electrical connection are required. Typical use cases include cabling of sensors, switches, drives, and other field devices in manufacturing plants, machine building, or logistics systems. The use of M12 connectors ensures a robust and weather-resistant connection that remains stable even with frequent plugging and unplugging.

Functions and Equipment in Detail

The distribution box features eight socket positions, each equipped with a plastic M12 socket. The sockets are designed for a pin count of five and have coding A, representing the standard connection for industrial sensors and actuators. The socket assignment is double, meaning two devices can be connected per socket position, thereby increasing the number of controllable end devices. The box is universally applicable and does not require a special status indicator, as it does not offer integrated diagnostic functions.

Technology Explained Simply

The main cable connection is made via an M23 connector with a 90° angle, enabling a compact and space-efficient installation. This connection is designed for linking to a main cable, for example, from a control device or network device. The connection is unshielded, which is sufficient for applications where no high electromagnetic interference is expected. The M12 sockets provide a mechanically stable connection and are designed for use in industrial environments where high mechanical loads and frequent cabling occur.

Compatibility and Accessories

The SACB-8/16-M23 is compatible with various accessories that facilitate installation and maintenance. These include, for example, the PLUSCON-RCS pipe wrench, which ensures secure installation of connectors, and the TSD 04 SAC torque screwdriver, which ensures precise and controlled connections. Other compatible components include plug inserts such as SAC BIT M12-D15 or M12-D20, used during installation of M12 connectors. Connection sockets such as RCK-TWUM/BL16+3/5,0PUR-U or RCK-TGUM/BL16+3/10,0PUR-U, as well as the main cable RCK-TGUM/BL16+3/5,0PUR-U, are also compatible and can be used to extend the cabling. The locking screw PROT-M12 serves to securely fasten the connectors, while the protective cap KSK 1 protects the sockets from contamination. The label tape ZBN 18:UNBEDRUCKT can be used to mark the cables.

Installation and Mounting

The sensor/actuator box is mounted at a suitable location in the machine or plant area, with the 90° configuration of the main cable connection enabling space-saving installation. The M12 sockets are connected to the corresponding connectors of the end devices, and the use of tools such as the torque screwdriver or pipe wrench is recommended to ensure a secure and durable connection. The box itself requires no additional installation technology, as it connects directly to the main cable.

Advantages in Operation

The SACB-8/16-M23 provides a reliable and structured cabling solution for industrial applications. The use of M12 connectors ensures high mechanical stability and simple, repeatable installation. The double socket assignment increases the number of controllable devices without requiring additional distributors. The universal design enables integration into various automation systems, and the lack of shielding is sufficient for many standard applications where no high electromagnetic interference occurs. The compatibility with various tools and accessories facilitates maintenance and component replacement.
