Question

Is it possible to extend the cable of the Proximity Sensor?

Answer

Yes, it provides as follows in each type of the sensor.

Built-in amplifier (the E2E Series, the TL Series)

The following occur.

Voltage descent by resistance component of cable

Extension of rise time of output waveform by the capacity between lines of cable

Therefore, please use the cable more than the same nominal cross-sectional area and make the length of the cable to the power supply within 200m.

Separate amplifier (the E2C Series)

The capacity between lines of the cable changes when the cable length between the sensor and the amplifier is changed, the oscillation frequency is changed, and the characteristic change in the sensing distance and the temperature characteristic occurs.

Therefore, it is not warrantable that the cable length between the sensor and the amplifier is made outside regulations.

Moreover, it is not warrantable that processing it to the cable like the extension by the customer even if it is in regulations.

Linear output separate amplifier (the E2CA Series)

The capacity between lines of the cable changes when the cable length between the sensor and the amplifier is changed, the oscillation frequency is changed, and the characteristic change in the sensing distance, the temperature characteristic and linear output occurs.

Therefore, the cable length between the sensor and the amplifier is 3m or 5m. Please specify the cable length with the selector of the amplifier side.
