*1. The condition of this distance are that the switch and actuator target marks are on the same axis and the sensing
      surfaces are exactly parallel condition. OFF to ON distance shows the switch approaching (Point A in the engineering
      data graph) and ON to OFF distance shows the switch separating away (Point B in the engineering data graph).
*2. For details on response time and operating time, refer to the catalog or manual of a safety controller to be connected.
*3. Power to be provided to the load is not included.
*4. For details, refer to item "Precautions for Correct Use".

Engineering Data

D40Z Specifications 3

Note: 1. The operating distance is the distance between the switch and actuator sensing surfaces.
         2. The graph of detection area indicates shifting to X or Z direction from following condition that the switch and
             actuator target marks are on the same axis and the sensing surfaces are exactly parallel condition.
             Dashed lines indate reference value for maximum and minimun oprating distance at abient temperature +23°C.
             The solid line indicates reference values of the maximum and minimum operating distances.
         3. The operating distance may be affected by ambient metal, magnet catches, and temperature.
         4. Detection may occur other than on the detection surfaces of the switch and actuator. Before you use the switch and
             actuator, refer to “Switch and Actuator Operation” on Data Sheet to set the detection surfaces of the switch and
             actuator face to face.
