Z4D-A01 Z4D-A01 Characteristics (Ta = --10°C to 55°C) Item Values (see note 2) Remarks Operating distance 6.5±1 mm From the reference mounting surface Variation of sensitivity ±10% (see note 3) Resolution ±10 µm (see note 4) Operable ambient illumination 3,000 ℓx max. 2,000 ℓx max. Under sunlight Under fluorescent lamp Note: 1. As measured between sensor and microprocessor. 2. The values are measured with a white paper having a 90% reflection factor. 3. Defined as the variation of sensitivity between products. The variation is the change of the calculated analog output by distance (slope of the straight output line.) Refer to “Microprocessor Divided Output vs. Distance” graph in Engineering Data. 4. The resolution means the electrical noise width on the calculated analog output converted into distance when using a 10-bit or more A/D converter.

The following features are characteristic of the optical displacement sensor when directly connected to a microprocessor provided by the user. 1. The color or the reflection factor of a sensing object has little effect on the analog output. 2. The inclined face of a sensing object has little effect on the analog output. 3. Linear compensation is not required Internal Configuration NOTE: DIMENSIONS SHOWN ARE IN MILLIMETERS. To convert millimeters to inches divide by 25.4. R OMRON ELECTRONICS LLC OMRON CANADA, INC.
