Description
This Harmony XB4, single contact block is pre-assembled on a body/collar fixing unit. This body fixing collar is pre-mounted with a contact block. Simply adding a head to this assembly will provide you with a complete ready-to-use push button. Its wide range of operating temperatures from -40°C to 70°C allows versatility in usage of product.
Features
- The ZB4BZ105 is a complete electrical block assembly from the Harmony XB4 metal range. It includes the ZB4BZ009 mounting collar (the "body") and two ZBE102 (Normally Closed) contact blocks. This assembly is the "engine" behind a 22mm push button, converting the physical press of the button into electrical signals for your control system.
- The 2 NC configuration is primarily used for safety and redundancy. In many Canadian industrial applications, "Stop" or "Emergency Stop" buttons require dual-channel wiring. This ensures that even if one contact block fails or a wire breaks, the second circuit can still trigger a safety stop, meeting higher Safety Integrity Level (SIL) requirements.
- As part of the XB4 line, the mounting collar is made of high-strength chromium-plated metal. This is designed to withstand the high torque, impact, and vibration found in Canadian mining, forestry, and heavy manufacturing environments, where plastic components might crack or loosen over time.
- The contact blocks feature heavy-duty screw clamp terminals designed for a gas-tight connection. These terminals are engineered to resist loosening even in high-vibration applications, ensuring reliable electrical continuity for both standard control wiring and low-energy PLC safety inputs.
- One of the best features of the Harmony range is its modularity. You can easily snap on additional ZBE contact blocks to this base (up to 3 blocks across, or 6 total if stacked) to accommodate more complex control logic or monitoring signals without needing to replace the entire assembly.
