Hawkeye 300 go/no go current switches provide a cost-effective solution for monitoring status on unit vents, exhaust fans, recirculation pumps, and other fixed loads where belt loss is not a concern..
Applications: Monitoring on/off status of electrical loads. Monitoring direct-drive units, exhaust fans, and other fixed loads. Verifying lighting run time. On/off status for direct-drive fans, pumps, and process motors. More reliable for status than relays across auxiliary contactsIdeal for direct-drive units, unit vents, fan coil units, exhaust fans, and other fixed loads. Great for lighting status. Less expensive than 277V relays. Low 0..
Ideal for small exhaust fans (not intended to detect belt loss. Removable mounting bracket provides installation flexibility. Monitor status of fans, pumps, motors & other electrical loads. Split-core for fast retrofit installation. Micro housing for tight enclosures..
Saves valuable panel space 100% solid-state, no moving parts to fail. Polarity insensitive output 5-year limited warranty..
