7. Application of ultrasonic proximity switch
Ultrasonic proximity switch
ultrasonic proximity switch is a device built-in circuit that can processes input and output signal, it is able to send and receive ultrasonic pulse detect the target approaching its operating range. It can work in diffuse, reflex or thru-beam mode, please refer to below figures:
1. Thru-beam
Figure 4-1
2. Diffuse beam
Figure 4-2
3. Retro-reflective beam
Figure 4-3
Characteristics
No physical contact with the object to be detected, therefore, no friction and wear;
Unlimited operating cycles since there is no mechanical contact with the target;
Ultrasonic proximity sensors are not affected by target color or atmospheric dust, snow, rain, noise etc;
Can work in harsh conditions;
Sensing distance is more compared to inductive or capacitive proximity sensors;
The targets to be detected can be in the solid, liquid, granular or powder state.
Applications:
Based on the characteristics, proximity switch is widely used below applications in practice (Note: below pictures cited from internet for explanation purpse, if any infringement on your interests, please inform us of this accordingly):
