Classification methods & Classification
Method of classification
(1) Classification by structure
This classification is based on whether the constituent circuit elements are built-in or separated. It is useful for selecting sensors in view of the mounting space, power supply, and noise immunity.
|
Inductive proximity sensor (High-frequency oscillation type) |
Amplifier built-in |
Amplifier-separated |
|
(2) Classification by coil enclosure
This classification is based on the structure surrounding the sensor head (detection coil). It is useful for selecting sensors in view of the mounting style, sensing range, influence of surroundings, etc.
|
Inductive proximity sensor (High-frequency oscillation type) |
Shielded |
Non-shielded |
|
(3) Classification by output circuit
This classification is based on the type of output circuit and the output voltage. This classification is useful to select sensors according to the input conditions of the device or equipment connected to the sensor output.
|
Inductive proximity sensor (High-frequency oscillation type) |
ON / OFF output |
NPN open-collector transistor |
PNP open-collector transistor |
DC 2-wire |
Analog output |
Analog voltage |
Analog current |

Classification
(1) Classification by structure
Type |
Outline and Features |
Amplifier built-in |
- As the amplifier is built-in, a non-contact output is obtained simply by connecting a DC electric power supply.
- It has high noise immunity because the amplifier is builtin.

|
Amplifier-separated |
- The sensing portion can be made small since the detection coil is separated as the sensor head.
(However, its noise immunity is less than that of the amplifier built-in type.)
- The sensitivity setting can be done on the amplifier at a remote place.
