4100 Series Zero Speed Switches
4100 Series zero speed switches are designed for service in industrial applications requiring protection against rust, rain, and hose directed water. 4100 Series switches are for shaft input speeds of 24 to 1800 RPM. Recommended method of driving is by split or flexible coupling.

Contacts actuate in either direction of shaft rotation. Housings are painted with an epoxy based powder coat to provide rust and corrosion resistance.

Designed for V-belt or roller chain and sprocket drives. Driving torque required is approximately 4 inch ounces. Install with loose belt or chain to avoid excessive overhung load.

NEMA 4/4X

Available housings: Aluminum (AL) and Cast Iron (CI).

Approximate shipping weight:
Aluminum housings: 4 lbs.
Cast Iron housings: 8 lbs.
