GHU9
OVERSPEED SPEED SWITCH, GHU9 SERIES
The overspeed switch function on the 90mm range – a sturdy mechanical security module without external power supply:
 radial commutation centrifugal switch without permanent contact.
 high quality mechanics reliability.
 excellent repeatability.
 securised system, works without power supply.
 modular mounting possibility.
 commutation speed : standard calibration range between 800 and 4 000 rpm (rotation per minute).
Especially designed for heavy duty industry (steel and paper mills, lumber, cranes, engine etc...). Sturdy compact conception.
Excellent resistance to shocks/vibrations and to extreme axial/radial loads.
20mm blind shaft (reduction hubs available).
Blind shaft GHU9_20 with overspeed switch 20mm blind shaft triple mounting example
The compactness of the assembly, which can be proposed by BEI SENSORS, allows the combination of overspeed switch and encoder
presenting a particularly interesting cost / performances relation.
