2-way open switch ST22\01-2

Open-type connector for DIN rail mounting

This connector with a break contact, designated as ST22\01-2, is designed for front mounting, specifically from above. It is an element used in the construction of control and signaling circuits where signal switching is required upon activation.

Construction and application

The ST22\01-2 connector is characterized by a screw connection, which ensures a secure and reliable electrical connection. Its design allows for mounting on a DIN rail, which simplifies and speeds up the installation process. It is designed to operate with a rated current of 2.5A for AC-15 at a voltage of 230V. The lack of a socket makes it a raw element that can be adapted to specific application needs.

Advantages in practice

• Simple mounting: Front mounting from above minimizes the time required for installation, especially in tight spaces.
• Reliable connection: Screw connection guarantees stability and safety of electrical connections.
• Compact dimensions: The dimensions of the connector (44 x 37.5 x 24 x 10 mm) allow it to be used in limited space.
• Precise operation: The minimum force required to reach the open position (11 N) ensures precise and smooth operation.
• Durability: Tightening torque of the terminals of 0.5 Nm ensures a stable and secure connection of the wires.
• Lightweight construction: The weight of the connector (11g) makes it easier to install and does not burden the supporting structure.

Additionally, the maximum travel of the connector, including the end travel, is 6 mm, which affects the precision of the switching mechanism. This connector has one break contact – which means that the circuit is open at rest and closes after pressing or activating the mechanism. The lack of fault signaling contacts and normally closed contacts simplifies the construction and focuses functionality on the basic task – switching the circuit.
