OMRON ZX2-LD50 (01) PDF MANUAL

Do not use the product in environments where it can be exposed to inflammable/explosive gas. To secure the safety of operation and maintenance, do not install the product close to high-voltage devices and power devices.

Use only products that have been made expressly for the Controller. High-Voltage lines and power lines must be wired separately from this product. Wiring them together or placing them in the same duct may cause induction, resulting in malfunction or damage. Always turn off the power of the unit before connecting or disconnecting cables.

Make sure to tighten all installation screws securely (tightening torque: M3, 0.5N·m).

Do not attempt to disassemble, deform by pressure, incinerate, repair, or modify this product. When disposing of the product, treat as industrial waste. If you notice an abnormal condition such as a strange odor, extreme heating of the unit, or smoke, immediately stop using the product, turn off the power, and consult your dealer.

Do not install the product in locations subjected to the following conditions:

Surrounding air temperature outside the rating

Rapid temperature fluctuations (causing condensation)

Relative humidity outside the range of 35 to 85%

Presence of corrosive or flammable gases

Presence of dust, salt, or iron particles

Direct vibration or shock

Reflection of intense light (such as other laser beams, electric arc-welding machines, or ultra-violet light)

Direct sunlight or near heaters

Water, oil, or chemical fumes or spray, or mist atmospheres

Strong magnetic or electric field

Use only products that have been made expressly for the Controller. To extend the cable from the sensor head, an optional extension cable (ZX2-XCR) must be used.

After turning on the power supply, allow the Controller to stand for at least 10 minutes before use. The circuits are unstable immediately after the power supply is turned on and attempting measurement may result in inconsistent measurement values.

Always turn off the power of the unit before connecting or disconnecting cables. Do not use thinner, alcohol, benzene, acetone, or kerosene to clean the sensor. If considerable foreign matter or dust collects on the front of sensor, use a blower brush (for camera lenses) to blow off the foreign matter. Avoid blowing it off with your breath. For a small amount of foreign matter or dust, gently wipe with a soft cloth. Do not wipe hard. If the surface is damaged, false detection may result.

The product cannot accurately measure the following types of objects: Transparent objects, objects with an extremely low reflective sensor ratio, objects smaller than the spot diameter, objects with a large curvature, excessively inclined objects, etc. Set scaling regularly to maintain accurate detection.

Inserting a calculation unit between amplifier units can prevent mutual interference between sensor heads. However, this may not work efficiently if the amount of light received by one sensor head is saturated because of the luster of work-pieces and a laser beam from the other sensor head is input. If you are interested in installing a calculation unit in order to prevent mutual interference, carry out a test using the actual system beforehand.

The specifications for the ZX2-LD sensor heads are as follows:

F.S.: Full scale of measurement

(*1) Beam diameter: Value of minimum diameter in measuring range. The typical value at the measuring center distance is shown. Defined as 1/e² (13.5%) of the center intensity. The beam diameter may sometimes be affected by the ambient condition of the object such as leaked light from the main beam.

(*2) Resolution: Fluctuation width of linear outputs when connected to Amplifier Unit (With response time set to 128ms and the standard work (white ceramics) placed at the measuring center distance). This value is repetition accuracy of the static condition work, and not distance accuracy. In a strong electromagnetic field, the performance of resolution might not be able to be satisfied.

(*3) Linearity: The error in relation to the ideal displacement output straight line when the standard work is measured.

(*4) Temperature characteristic: Value obtained when the sensor and object (standard work) are fixed with an aluminum jig. (Measured at the measuring center distance)

Fix the Reflective type sensor head with screws (M3). Tightening torque is 0.5Nm.

When mounting a Sensor Head, take care not to touch the emitter and receiver. Adhesion of finger marks may hinder correct measurements. If you have touched them, wipe them with a clean soft cloth.

A ferrite core (supplied with the sensor head) must be attached to the sensor cable. The ferrite cores can be connected within 100 mm from the sensor.
