SMC D-A73C internal circuit reed auto switch is used in pneumatic and hydraulic systems for automation & control applications. This switch detects the position of a piston or cylinder rod within the system by utilising a reed switch that activates by a magnetic field generated by a moving magnet embedded in the piston or rod. When the magnet aligns with the reed switch, it triggers an electrical signal, allowing for precise position sensing.
Working Mechanism:
- A reed switch is a simple electromagnetic switch used in various applications.
- It consists of two thin, magnetisable and electrically conductive reed-like metal strips sealed within a glass tube.
- In its natural state, the switch remains open, but when a magnetic field is applied near the switch, it causes the metal strips to attract and make electrical contact, closing the switch.
- Removing the magnetic field causes the metal strips to separate again, opening the switch.
- This mechanism enables reed switches to function as reliable sensors or switches in devices, such as proximity sensors, magnetic door alarms and reed relays.
Features:
- This auto switch has a rectangular body style for integration into various industrial equipment and systems.
- It utilises a connector type for ease of installation & maintenance, ensuring a secure electrical connection.
- This device has a voltage rating of 24V, ensuring compatibility with common industrial voltage levels.
- It comes with a current rating of 0.04A to handle low-level electrical currents efficiently.
- This internal circuit reed auto switch has a rail mounting type for simplifying the installation process and ensuring stability in the setup.
- It includes vertical entry of wire for flexibility in how wires are routed and connected within the system.
- This component belongs to the primary type of proximity sensors, facilitating precise detection of nearby objects or components.
Frequently Asked Questions:
Q. How can I tell if the fuse in Bussmann fuse block has blown?
A. A blown fuse frequently has a clear break in the fuse element and the fuse's transparent window (if applicable) might look discoloured. You can determine whether a fuse is intact or blown by using multimeters.
Q. What is the voltage requirement for this reed switch?
A. This D-A73C reed switch operates at 24VDC.
Q. How do I install this D-A73C reed auto switch?
A.
- Choose an appropriate location for the reed auto switch's installation.
- Prepare the mounting surface by cleaning it thoroughly.
- Use suitable mounting hardware to secure this auto switch in place.
- Identify the wires, including common (COM), normally open (NO) and normally closed (NC) terminals.
- Provide a 24VDC power supply for this auto switch.
- Connect the COM wire to the power supply's positive terminal.
- Wire the NO or NC terminals as required for your application.
- Test this reed auto switch's functionality before finalising the installation.
- Protect wires with insulating materials like heat shrink tubing or cable conduits.
- Securely fasten and route the wires to prevent interference.
Q. What are the factors to consider while choosing this D-A73C reed auto switch?
A. Major factors include voltage compatibility, mounting options, sensitivity, load capacity, response time, environmental conditions and durability to ensure it meets your application's specific needs.
