2-way short-circuit track connector ST22\10-2-SZ

Universal rail connector – reliability and simple installation

This 2-pole rail connector, designated ST22\10-2-SZ, is an element designed for building control and signaling circuits. Its construction provides a solid connection and easy integration with rail systems. This is particularly important when building distributed automation systems, where minimizing downtime and ease of maintenance are crucial.

Construction and principle of operation

The connector is based on a latching mechanism, which means that the circuit is normally closed. Switching occurs through physical action on the connector's actuator. Thanks to this solution, even in the event of a control power failure, the circuit remains in a safe state – short-circuited. This is important from the point of view of the safety of devices and installations.

• Mountage: The connector is designed for mounting on a standard rail, which greatly simplifies and speeds up the installation process. This eliminates the need for additional mounting elements and ensures a stable connection.
• Weight: Low weight (11g) makes it easier to work with during installation and does not burden the rail structure.
• Force required to open: The required force of 11N to achieve effective opening ensures reliable operation of the mechanism and minimizes the risk of accidental switching.
• Tightening torque of clamps: The tightening torque of the clamps is 0.5 Nm – it should be observed when connecting wires to ensure optimal electrical contact and avoid damage to the clamps.
• Stroke: The maximum stroke of the mechanism is 6 mm, which affects the switching accuracy.

Applications

The ST22\10-2-SZ connector finds application in a wide range of electrical installations and industrial automation:

• Electric motor control
• Device status signaling
• Alarm systems
• Building automation
• Distributed control systems

Thanks to its versatility and reliability, this connector performs well both in new installations and during the modernization of existing systems. Its compact size allows it to be used even in limited space.
