Thermo Scientific ROS-4E-1-4-NPT Belt Misalignment Switch with NPT thread, 4 SPDT, NEMA 4

Model: ROS-4E-1-4-NPT | Order No: 141204

Used to monitor the position and tracking of conveyor belts, this belt misalignment switch (runoff switch) is mounted on the conveyor’s structure and when a belt drifts out of alignment, it sends an alarm signal. Equipped with a by-pass lever that bypasses the shut-down contact to allow the restarting of the belt.

Utilize a rugged, heavy-duty design and are built to last.

Features

  • Used to monitor position and tracking of conveyor belts
  • Mounts on conveyor structure and adjusts so roller arm is the proper distance and angle from outside edge of the belt
  • If belt drifts out of alignment, it contacts the roller actuator arm, which rotates the actuation shaft and triggers the belt misalignment alarm signal
  • Modular design of the base unit for added convenience during installation and maintenance
  • Rugged cast aluminum, heavy-duty design
  • Protection degree IP65 for long last and many years of dependable service
  • Suited for the most challenging applications
  • Can be operated from any direction as microswitches allow clockwise or counterclockwise rotation of the external lever
  • Cover locked by four shake-proof stainless-steel screws
  • Internal terminal board allows easy connection and faster maintenance procedures
  • Available with ATEX22 and ATEX21 approvals

Applications

  • Monitor your conveyors, equipment and processes
  • Prevent accidents and protect equipment
  • Used for position information, control signals and to identify potentially hazardous situations with your process equipment
