Conveyor Protection & Safety Switches (Ramsey)

Conveyor Protection Switches

Ramsey Pro-Line Belt Misalignment Switch
Part of the Pro-Line conveyor protection switch family, which also includes safety cable pull and tripper switches. Designed to monitor belt alignment and run-off conditions and activate alarms or shutdowns in hazardous situations.

Typical part variants include:
ROS-2E-1-4-NPT, ROS-2E-3-4-NPT, SPS-2E-1-4-NPT, SPS-2E-3-4-X, TPS-2E-…
(Pull-cord and tripper versions are listed in distributor catalogs.)

Tilt / Plugged Chute Switches

Ramsey 20-39-25 Conveyor Tilt Switch
A tilt-activated switch commonly used to detect conveyor misalignment or plugged chute conditions. Activates at a preset angle and is part of the broader Ramsey switch lineup.

Other Ramsey Switch Types

These switches are typically sold under specific model numbers and may not always appear as standard catalog SKUs.

Conveyor & Motion Monitoring

• Safety Cable Pull Switch (Ramsey SAS / SPS)
  Emergency stop switch activated by pull cord. Common models include SAS-2E, SPS-2E, SPS-4E.
• Tripper Position Switch (TPS)
  Heavy-duty limit switch used for monitoring tripper positions.
• Under-Speed Switch (Model 60-23P)
  Detects conveyor drive under-speed conditions and can trigger alarms or shutdowns.
  Typical Cat. No.: 15360

Tilt & Level Switches (Material Handling)

• Tilt Switches (e.g., 20-39-8M, 20-39-15M)
  Used to detect material buildup, pile conditions, or plugged chutes.
• Additional tilt, limit, and proximity switches are available across the Ramsey switch range.
