ABB Emergency Stop Pushbutton 1NO1NC Red 1SFA619500R1071

The ABB emergency stop pushbutton is a high-performance industrial control device engineered for safety-critical operations. Featuring a prominent red mushroom-head design, this unit is built to provide immediate and reliable machine shutdown during emergency situations. It is equipped with 1NO and 1NC contact blocks, ensuring versatile integration into safety circuits to protect both personnel and industrial equipment.

Advantages

This emergency stop pushbutton stands out due to its robust construction and high reliability in demanding industrial environments. The intuitive mushroom-head design allows for quick activation even when wearing gloves, ensuring that safety protocols can be executed without delay. Its dual contact configuration provides flexibility for various control system architectures, while the high-quality materials ensure long-term durability and consistent performance under frequent use.

Suitable for

• Industrial automation systems
• Emergency shutdown circuits for machinery
• Manufacturing production lines
• Control panels for heavy equipment

When it may not be suitable

This device is specifically designed for emergency stop functions and is not intended for use as a standard operational start or stop switch. It may not be suitable for environments with extreme chemical exposure or high-pressure washdown requirements unless housed in a compatible protective enclosure.

Key specifications

• Contact configuration: 1NO and 1NC
• Actuator type: Red mushroom-head
• Application: Emergency stop
• Design: Industrial control component

How to use

The pushbutton should be mounted securely onto a control panel or enclosure that meets the required installation standards. Once installed, the contact blocks must be wired into the machine's safety control circuit according to the electrical schematic. In an emergency, the operator presses the red mushroom head, which mechanically locks the switch in the depressed position to interrupt the circuit. To reset the system, the button is typically released by pulling or twisting, depending on the specific mechanical configuration, allowing the machine to be restarted safely.

What to consider before purchase

• Ensure the contact configuration matches your safety circuit requirements.
• Verify the panel mounting hole diameter compatibility.
• Check if the environmental conditions require an additional IP-rated enclosure.

Usage recommendations

Regularly inspect the pushbutton for mechanical integrity and perform periodic functional tests to ensure the safety circuit triggers the machine shutdown as expected.
