D4NS-2AF is a standalone safety switch engineered for machine guarding. It includes 1NC/1NO slow-action contacts and a Type 2 interlock mechanism, ensuring safety compliance across industrial zones. The D4NS-2AF model uses a G1/2 conduit outlet and supports direct opening with a minimum force of 60 N and a 10 mm travel to activate mechanical separation.
Industrial systems rely on D4NS-2AF for its robust environmental protection. The switch features an IP67-rated housing that resists water, dust, and debris. It operates within a wide temperature range from β30Β°C to 70Β°C and handles mechanical shocks up to 1,000 m/sΒ². Electrical specifications include a 300 V rated insulation voltage and 100 MΞ© insulation resistance, making the D4NS-2AF reliable for integration into safety control circuits.
Automation engineers choose D4NS-2AF for its compact size, durability, and mechanical precision. Weighing just 96 g, D4NS-2AF is easy to install in tight spaces such as machine panels, robotic gates, or packaging enclosures. Its ability to withstand vibration and deliver consistent contact performance makes it a trusted model for interlocking systems.
Applications of D4NS-2AF Safety Door Switch
The Omron D4NS-2AF is commonly used on machines that have doors, gates, or guardsβplaces where safety is critical. It prevents the machine from starting if the door is open and can also stop the machine immediately if someone opens the door while itβs running. This safety switch is found in packaging lines, CNC machines, conveyors, and robotic cellsβanywhere there's a risk of injury due to moving parts. It ensures the machine only runs when all safety doors are fully closed and locked. The D4NS-2AF has slow-action contacts, which provide stable switching even when vibration is present. This is especially useful in factory environments where machines run continuously, and conditions are not always ideal. It also supports direct mounting on metal frames or panels, making installation quick and reliable. No need for extra brackets or alignment tools in most cases.
