Omron, ZX-E Series

Wide Selection of Sensor Heads

Smallest Heads in Its Class at 3 Dia.

Small Sensor Heads are perfect for detecting the height of small objects and for applications where multiple Sensor Heads are used.

Sensors with stainless steel Protective Spiral Tubes are also available.

New Flat and Heat-resistive Sensors Broaden Application Possibilities

The temperature characteristic ranks at the top in the industry at 0.1% FS/°C for heat-resistive sensors, and it ranges up to 200°C for flat sensors.

More Efficient Maintenance

Complete Compatibility between Sensor Heads and Amplifier Units

The Amplifier Unit can be used as is when replacing damaged Sensor Heads or changing the Sensor Head for different detection distances.

Sensor Head Cords Extendable to 10 m

The distance between the Amplifier Units the Sensor Heads can be extended to 3 m, 6 m, or 10 m using a ZX-XC[]A Cable (sold separately).

Complete Range of Useful Functions

Simple Linearity Adjustment

Adjustments using the adjustment knob are no longer required to adjust linearity. Linearity adjustment is completed simply by teaching at 0%, 50%, and 100% of the measurement distance, greatly reducing setting time.

Suitable for Non-ferrous Metals Also

Linearity is worse for non-ferrous than ferrous sensing objects. A material selection function has been developed to improve linearity with stainless steel and aluminum sensing objects.

Mutual Interference Prevented for Up to 5 Sensors

Multiple Sensors may be used in confined spaces for level difference measurements or multiple-point measurements. Mutual interference between up to 5 Sensors can be prevented simply by connecting Calculating Units to eliminate the need for timing signals on the user side.

Calculation Settings without Digital Panel Data

The calculation results from two Sensors can be displayed on the Amplifier for one Sensor simply by placing a Calculating Unit between the Amplifier Units. The required parameters need to be input only into one Amplifier Unit.

*1: Resolution: The resolution is the deviation (±3σ) in the linear output when connected to the ZX-EDA Amplifier Unit. The above values indicate the deviations observed 30 minutes after the power is turned ON.
(The resolution is measured with OMRON's standard reference object at 1/2 of the measurement range with the ZX-EDA set for the maximum average count of 4,096 per period.)
The resolution is given at the repeat accuracy for a stationary workpiece, and is not an indication of the distance accuracy. The resolution may be adversely affected under strong electromagnetic fields.
*2: Linearity: The linearity is given as the error in an ideal straight line displacement output when measuring the standard reference object. The linearity and measurement values vary with the object being measured.
*3: Temperature characteristic: The temperature characteristic is measured with OMRON's standard reference object at 1/2 of the measurement range.
*4: The ambient temperature given is only for the sensor head. It is -10 to 60°C for the preamp.
*5: The value given is for an ambient temperature of 25°C.
*6: Do not use in moist environments because the case is not waterproof.
