1 Compact Non-Contact Do Switch/Flexible Safety Unit D40A/G9SX-NS Electronic Detection Mechanism f Better Stability in Non-contact Do Switch Operation CSM_D40A_G9SX-NS_DS_E_3_2 Be sure to read the Safety Precautions on page 24 and the Precautions f All Safety Do Switches. Features Easy-to-see 2-Col Indicats Switch status is easy to see at a glance with these red/yellow LED indicats. Mount from Either Side Mount from whichever side provides the easiest wiring path to enable mounting to all types of dos. Red: Open do detected. Yellow: Closed do detected. Not lit: Power OFF failure Swinging dos Sliding dos Small Actuat An actuat that is smaller than the switch saves space, even inside the do. Even when mounted with an L-bracket, the actuat's height will not hinder installation operation. Compact Switch Actuat Connect Up to 30 Switches to a Single Controller Reduce costs by connecting up to 30 Switches to a single Controller. Up to 30 Switches 1

2 Solves Conventional Switch Issues to Provide Stable Detection Issue 1 The Switch does not accurately detect the do when it is closed slowly, resulting in an err. Conventional switch Do closed slowly. An err can occur if the do is closed slowly with conventional switches. Solution 1 Magnet Conventional Switches Slow Reed switch contacts Magnet Reed switch contacts Err If the switching timing of reed switch contacts 1 and 2 varies too much, the Controller detects an err and turns OFF the output to maintain safety. Note: The figure is intended only as an illustration. Stable Detection with the D40A's New System The D40A does not use reed switches and provides stable detection with electronic switches. Slow Detects slow lateral operation. Detects slow rotating operation. Issue 2 It is nearly impossible to tell which do is open in a multi-do application. If an err occurs... The system cannot be started because the Controller has turned OFF the output even though all dos appear to be closed. It's impossible to tell if there is a do open if an err has occurred. All dos must be opened and closed befe operation can be started. Solution 2 With the D40A... The auxiliary outputs can be used to easily indicate which do is open. And with two-col indicats, mounting adjustments are also easy. The D40A is the first Non-contact Do Switch to combine 2-col indicats, auxiliary outputs, and 30-switch connection capacity, allowing you to create a better safety environment. 2

3 Two Types of Controller to Solve Productivity, Expandability, and Maintenance Issues The G9SX-NS and G9SX-NSA are designed specifically f use with the D40A, and with the G9SX-NSA you can also connect mechanical safety do switches. Among other features, these Controllers suppt logical AND connections that enable partial stops. These Controllers make the most of D40A Switches. Two Different Controllers AND connection input AND connection instantaneous safety plus mechanical safety do switch input, channel 1 instantaneous safety OFF-delay safety AND connection AND connection output Indicats That Make Maintenance Easier The indicats show the location and cause of wiring errs and any other errs that are detected. Auxiliary outputs f errs also contribute to reducing down time. Input err Logical AND connection err Output err Mechanical Safety Do Switches Can Also Be Connected with the G9SX-NSA Inputs can be accepted from both D40A Switches and mechanical switches to reduce the number of Controllers and costs. D40A Safety Do Switches Expansion Units to Easily Increase the Number of Outputs with the G9SX-NSA The number of outputs can be easily increased using connects. Up to 25 outputs can be configured. G9SX-EX Expansion Unit Up to 25 Outputs 3

4 Reduce Costs with these New-Concept Controllers Issue 1 Two Controllers are required f emergency stop switches and non-contact do switches. Application One hazard. The system must be stopped when either a do is opened an emergency stop switch is pressed. D40B D40B-J1 Solution 1 Emergency stop switch * D40A Emergency stop switch * The D40A Simplifies the Configuration The G9SA must be added to connect the emergency stop switch. G9SA Two Controllers With only one G9SX-NSA222-T03@ Controller, both a Non-contact Do Switch and an emergency stop switch can be connected. G9SX-NSA One Controller Issue 2 Another Controller has to be added to use an OFF-delay timer. Application Two hazards. The power supply must be turned OFF immediately when the emergency stop switch is pressed. When a do is opened, a stop signal is sent to only servomot B and then the power supply is turned OFF. Emergency stop switch * Wiring D40B D40B-J1 Solution 2 The D40A Simplifies the Configuration Emergency stop switch * G9SX-BC D40A G9SX-NSA The G9SA must be added to use an OFF-delay timer. A G9SA B G9SA-321-T@ OFF-delay output Three Controllers A Controller can be eliminated because the G9SX-NSA222-T03@ provides an OFF-delay output. A Logical AND connection B Two Controllers * Always use a manual reset when using an emergency stop. Refer to G9SX f the features of the G9SX Series. 4
