Description

The air ultrasonic sensor radiates ultrasonic waves in the air. In turn it also receives reflected wave from a target and measures distance from source to the target. Ultrasonic waves are also reflected by transparent objects thus can be used to detect transparent targets that cannot be detected by light or infrared rays. method of the transmission and reception of reflected waves can be selected to suit specific applications.

Mounting methods

• One sensor reflection method (T/R, dual-purpose)
• Two sensor reflection method (T/R, single-purpose)
• Two sensor opposed method (T/R, single-purpose) [Notes, T; transmitted, R; received]

Typical Applications

• Distance measurement
• Intrusion alarm sensors
• Object counting on the belt conveyors
• Automatic opening and closing door sensors
• Proximity switch in the FA facilities
• Equipment remote control sensors
• Flow sensor of liquid or gas
• Paper double-feed detection sensors
• Fluid level sensors & Water level sensors

Placement method of the ultrasonic sensor

FUS Series / Low-frequency type

FUS Series / High-frequency type

Notes on use

• The sensor has directivity. Note the mounting and direction.
• The negative terminal is connects to the case, and have been shielded. Please note the connection method. (except for the FUS-40E.)
• The sensor may be caused the noise by the impacts. Please use to holds the sensors in buffer material as foamed rubber.
• There is a possibility that the insulation resistance is lowered. Avoid DC voltage is applied for a long time.
• This sensor can not be used in water.
• For improvement, it may want to change the specifications without notice.
