Specifications
Non-contact Door Switches
Ratings and Characteristics
*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. Turns ON when the actuator is approaching. The G3R series of the SSR can be driven at an auxiliary output of 10 mA. Contact your OMRON
representative for details.
*4. For details, refer to item 5 on page 33.

Y-direction movement
Note: 1. The operating distance is the distance between the switch and actuator sensing surfaces.
2. The graph 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.
