This emergency stop push button is an essential component designed for safety in electrical and mechanical applications. The panel mount push button switch features a red mushroom head design with a diameter of 40mm, ensuring visibility during urgent situations. It requires a 22mm cutout for installation and operates on a voltage rating of 600V AC and 600V DC. With dimensions of 47mm in height, 40mm in width, and 82mm in depth, this device is suitable for various industrial uses.

• Designed for emergency stop functions with SPDT push button configuration
• Twist release mechanism enhances safe operation
• IP66, IP67, and IP69 rated for water and dust resistance
• DPST push button actuator provides dual functionality
• Screw clamp terminals enable secure and easy connections
• High mechanical durability of 300,000 cycles for long-lasting use

• Used within control panels for machinery in manufacturing
• Employed in robotic systems for safety shutdowns
• Applicable in electrical enclosures for effective emergency stops
• Ideal for automation systems requiring rapid response capabilities

The twist release feature prevents accidental activation, ensuring that the emergency stop function is only engaged when intentionally operated, thus reducing the risk of unintended shutdowns during critical tasks.

The high IP ratings indicate that the push button is dust-tight and can withstand high-pressure water jets, making it suitable for use in harsh environments, thereby maintaining reliability and safety.

Yes, it is capable of operating in ambient temperatures ranging from -40°C to 70°C, accommodating a wide range of environmental conditions typical in industrial applications.

This device features screw clamp terminals suitable for various wire sizes, simplifying the installation process and ensuring secure electrical connections as per IEC standards.
