Small Non-Contact Door Switch [D40A]
Uses a magnetic detection mechanism that provides more stable operation than conventional non-contact type door switches
[Features]
· The new non-contact door switch helps improve safety and productivity at production plants.
· The manufacturer has created a new compact non-contact type door switch that resolves a variety of problems associated with conventional types.
· Enables a stable level of detection that was not possible with conventional non-contact type door switches.
[Two-color LED Display With Excellent Visibility]
· The color of the LED changes red/yellow, allowing you to confirm the status of the switch at a glance when there are issues.
[Compact Size Actuator]
· As the actuator is smaller than the switch, it takes up little space, even inside doors.
· There are few protrusions, so it does not cause any obstruction when mounted with an L-shaped bracket.
[Can Be Mounted From Either Side]
· Can be mounted from whichever side that provides the easiest wiring path, enabling mounting to all types of doors.
[Connector Type for Reduced Labor-costs. Helps Keep Inventories Down]
· The use of a connector helps reduce time spent performing wiring.
· The cable length can be selected, allowing you to purchase just the required length.
· When considering installation onto multiple devices or devices with multiple doors, the main switch units can be integrated into a single switch, helping reduce inventory.
[Connect Up to 30 Switches Onto a Single Controller]
· When using a lot of switches, up to 30 switches can be connected onto a single controller, helping keep costs down.

*1.When the target marks of the Micro Switches and actuator are on the same axis and the sensing surfaces are aligned, this is the distance at which the switch changes from OFF to ON when approaching (point A on the characteristic data graph)and
the distance at which the Micro Switches changes from ON to OFF when moving away (point B on the characteristic data graph).
*2.For response time and operating time, refer to the catalog or manual of the connected safety controller.
*3.The Micro Switches turns ON when the actuator approaches. The solid-state relay G3R series is available as a relay that can be driven by the auxiliary output of 10 mA.
