Schneider Electric Momentary Actuation Pushbutton, Yellow, 22mm Cutout - Harmony XB4 Series - XB4BA51

Install this pushbutton from Schnieder Electric as a reliable control device for your industrial facilities. It's a durable choice that doesn't need much maintenance as the bezel is made of chromium-plated metal, which is highly resistant to corrosion. The slim, compact body fits into a 22mm-diameter cutout on your control panel and there's no need for complex wiring. A button depth of 52mm and a flush fit in the mount prevents accidental pressing.

Features & Benefits

• Yellow button head for clear identification

• Light 0.08kg weight for installation in tight enclosures

• Slow break contact enables gradual power down to prevent current overload

• Maximum operating temperature of +70°C for reliable use in demanding environments

Applications

• Manufacturing industry

• Security systems

• Conveyors and production-line equipment

What kind of contact operates the pushbutton?

As it uses a NO (normally open) contact, the button is always in an activated state. It won't deactivate unless it's manually depressed. This system is reliable as a power-control mechanism as it ensures the machinery it's connected to is constantly on.
