Milltronics ZSS is a heavy-duty zero-speed alarm switch. This non-contacting unit provides cost-effective equipment protection even in the harshest conditions.

This rugged unit is impervious to dust, dirt, build-up and moisture and is ideal for such primary industries as mining, aggregate, and cement plants. Operating where other systems are prone to failure, the non-contacting design eliminates the need for lubricating, cleaning and part replacement. Downtime and clean-up expenses associated with conveying equipment failure are reduced by the ZSS. It alarms to minimize spillage, prevent extensive damage or even fire caused by belt slippage at the head pulley and warn against conveyor malfunction.

The ZSS has built-in selectable start delays and 1 Form C relay contact. With a phenolic body, it operates from -40 ... +60 °C (-40 ... +140 °F).

Key Applications: tail pulleys, driven pulleys, motor shaft sensing, screw conveyor flights

• Up to 38 mm (1.5") gap between ZSS and targets
• Rugged, low maintenance suitable for tough environments
• 1 SPDT Form C relay contact
• Provides cost-effective protection
