Now you can easily detect when drive belts slip,
break, or pump couplings shear. In fact, a typical
HVAC motor that loses its load has a reduction of
current draw of up to 50%. That's why our sensors
are the industry standard for status.

808 Series
Mini Solid-Core Adjustable Setpoint Dig i tal
Output Current Switches

The Hawkeye 808 Series is a high per for mance miniature solid-core current
status switch. Its low minimum setpoint (0.75A) and small size make it ideal for
monitoring status of small to medium motor loads. With an amperage range of
0.75 to 50 amps, the 808 series can accurately detect belt loss, coupling shear, or
other mechanical failure on loads from 1/5 to 40HP.
APPLICATIONS
■ Detect belt loss, coupling shear and mechanical failure
■ Verify lighting circuit and other electrical service run times
■ Monitor status of industrial process equipment
■ Monitor status of critical motors (compressor, fuel, etc.)
High performance miniature solid-core
■ Low (0.75A) minimum setpoint...eliminates the need for multiple wraps of
the conductor through the sensor even on loads as small as 1/5HP
■ Small size fi ts easily inside small starter enclosures
■ Adjustable/Removable mounting bracket optimizes in fi eld versatility
■ Status LEDs for easy setup and local indication
■ 1 Amp status output for increased application fl exibility
Monitor status of fans, pumps & elec trical loads
■ Detects belt loss and mechanical failure...ideal for fan/pump
status monitoring
■ Reliable cost-eff ective fan/pump status sensor...the 808 series replaces
pressure switches and other elec tro me chan i cal devices...no fi tting
or tapping required
■ Adjustable set point (0.75-50A)
■ 100% solid state...no moving parts to fail
■ 5-year limited warranty
