DAZIC® 2100 Series

2100 Series Zero Speed Switch

Operating Range: 4 to 2000 RPM

The 2100 Series Zero Speed Switches are electromechanical rotary motion controls requiring no electrical input to operate.

These switches are designed for systems that have a high RPM.

These shaft-driven devices can let you know if equipment is running too fast, too slow, or not at all. These UL-approved speed switches can be interlocked as part of a material handling system to ensure that if one machine fails, the entire operation will stop, avoiding an expensive and time-consuming pile-up of material and potential breakage of equipment.

  • For shaft input speeds of 4 to 2000 RPM.
  • Will operate in temperatures ranging from -40° F to +250° F (-40° C to +482° C).
  • NEMA 4/4X housings are painted with an epoxy-based powder coat to provide corrosion resistance as well as protection against dust, rain and hose-directed water.

The DAZIC Speed Switch devices coupled to a corresponding shaft, must be properly mounted and aligned to avoid putting extra load on DAZIC bearings and help prevent any premature failure caused by improper installation. 

The use of installation accessories such as Mounting Brackets and K-Couplings provide a secure foundation and eliminate misalignment connection problems. The DAZIC installation accessories are designed specifically for our speed switches to ensure its optimal operations.
