Classification1
Self-contained type (EV, EZ, ED)
- ・The sensor can be used as soon as the power is turned on. (Simplified wiring)
- ・Sensitivity adjustment not possible
Separate-amplifier type (ES)
- ・Small sensor head (Wiring is required between the sensor head and amplifier.)
- ・Longer detecting distance compared with
the self-contained type - ・Fine adjustment is possible with a sensitivity adjustment trimmer, which enables high accuracy detection.
Amplifier-in-cable type (EM)
- ・The sensor can be used as soon as the power is turned on. (Simplified wiring)
- ・Small sensor head and amplifier
- ・Sensitivity adjustment not possible
Classification2
Shielded type
The side of the sensing coil is covered with metal shielding. This type can be used by being embedded in metal. (Excluding the EM Series)
Non-shielded type
The side of the sensing coil is not covered with metal shielding. This type offers a longer detecting distance compared with the shielded type. Since the sensor is easily affected by surrounding metal objects, attention is required for the mounting position.
