The SICK IN4000 Direct Series Safety Switch are inductive safety switches that monitor position, and operate on a non-contact measuring principle. These switches are actuated through ST37 steel, eliminating the need for a separate actuator. The IN4000 Direct Series has two safety outputs which can be directly connected to a safety-enhanced electronic evaluation system. This product line offers easy adjustment with straightforward mounting, along increased shock and vibration resistance.

Applications

  • Position determination of hazardous movements
  • Position monitoring in areas with limited access
