Tell machinery when to stop and when to go with this auxiliary contact block from ABB. It has one NO contact that remains open until preset conditions are met, boosting the safety of your machinery. When a control signal is sent to the unit, it breaks or makes the electrical connection, so it's an ideal choice for devices like limit switches that need precise and rapid responses. Thanks to the block's insulation voltage rating of 690V, you and your equipment are protected from electrical faults.

• Front-end mounting design is simple to install and inspect
• Screw terminals for easy installation without the need for complex tools
• Low power loss of 0.1W per pole for energy efficiency
• Mechanical durability of 10 million cycles supports long-term performance
• 24V AC contact voltage rating suits low-voltage applications

• Chemical and petrochemical manufacturing
• HVAC systems
• Automotive industry

This block has compact dimensions of 32.5 (L) x 9.5 (W) x 46.8mm (H), so it's easy to handle and fits into most small enclosures. It tips the scales at just 143g, so won't weigh your setup down.
