SCHNEIDER 140CPU11303 Buttons

Schneider Electric is a global leader in human-machine interface (HMI) components, primarily through its world-renowned Harmony range (formerly Telemecanique). These buttons are engineered for ergonomics, durability, and easy integration into control panels.

Product Detailed Description

The Schneider Harmony series consists of two main categories:

• Harmony XB4 (Metal): Heavy-duty, chrome-plated metal bezel designed for harsh industrial environments.

• Harmony XB5 (Plastic): Double-insulated, corrosion-resistant plastic bezel ideal for chemical environments or food and beverage industries.

These buttons are modular, consisting of an operator head, a fixing collar, and contact blocks (NO – Normally Open or NC – Normally Closed).

Technical Parameters (Typical)

Product Advantages

• Modular “Plug & Play” Design: Operators and contact blocks can be mixed and matched. You can snap on up to 9 contact blocks depending on the model.

• Robustness: High resistance to chemical agents, dust, and water ingress. The XB4 series is particularly famous for its “industrial toughness.”

• Ease of Installation: Features a single-screw “locking” system and “shake-proof” terminals that prevent wires from loosening due to vibration.

• Global Standards: Fully compliant with IEC, UL, CSA, CCC, and CE, making them suitable for export machinery worldwide.

• Aesthetics: Ergonomic designs with bright, high-visibility LED illumination (for lighted versions) that lasts up to 100,000 hours.

Important Considerations (Precautions)

• Tightening Torque: Do not overtighten the fixing screw on the collar, as it may crack the plastic housing or the mounting panel.

• Contact Loading: For low-energy switching (PLC inputs), use Gold-flashed contacts to prevent oxidation buildup that can occur with standard silver contacts.

• E-Stop Reset: Ensure the Emergency Stop button is the “Trigger Action” type (EN/ISO 13850) to prevent accidental reactivation before the fault is cleared.

• Environment: Use XB5 (Plastic) in environments where the button may be exposed to cleaning detergents or salt spray to avoid metal corrosion.

Product Applications

• Industrial Automation: Start/Stop controls for conveyors, motors, and production lines.

• Infrastructure: Control panels for water treatment plants, airports, and tunnel ventilation.

• Food & Beverage: IP69K-rated buttons used in areas requiring frequent high-pressure steam cleaning.

• Elevators & Hoists: User interface buttons for floor selection and emergency signaling.

• Energy: Control desks for power distribution and generator sets.
