Magnetic Reed Switch Baomain D-A93 10mm NO for Pneumatic Air Cylinder

Description

Product Overview

The Baomain D-A93 magnetic reed switch is engineered to provide dependable, contact‑less switching for a wide range of industrial applications. Constructed from high‑quality sealed glass encapsulated reeds, the device offers excellent resistance to dust, moisture, and vibration, ensuring consistent performance even in harsh environments. Operating voltage spans from 10 to 30 V DC with a maximum current rating of 200 mA, the switch is designed for low‑power control circuits commonly found in pneumatic systems. Its compact 10 mm diameter, normally‑open (NO) configuration allows it to fit into tight spaces where larger mechanical switches cannot be accommodated. The included 2 m lead wire, made from flexible yet durable copper, simplifies wiring and reduces installation time. With a weight of just 36 g, the sensor can be mounted on moving components without adding significant load, making it ideal for air cylinder end‑of‑stroke detection, valve actuation, and safety interlock applications. The product meets IEC standards for electromagnetic compatibility and has been tested for long‑term reliability, providing peace of mind for engineers seeking a proven solution.

Usage

Designed for pneumatic air cylinder systems, the D‑A93 reed switch excels in environments where precise position sensing is required. It can be installed on the piston rod of a cylinder to detect the fully retracted or extended position, triggering downstream control logic for automated processes. The sensor’s magnetic actuation means there is no physical wear on the switching element, resulting in a virtually limitless operational life compared to mechanical limit switches. Typical use cases include robotic assembly lines, material handling equipment, and packaging machinery where rapid, repeatable motion must be monitored. Because the device operates on low DC voltage, it integrates seamlessly with PLCs, microcontrollers, and dedicated relay modules. The 2 m lead length provides flexibility for routing through conduit or cable trays, and the NO contact ensures that the circuit remains open until the magnetic field is present, reducing false triggering caused by electrical noise. Additionally, the switch can be employed in safety‑critical applications such as emergency stop circuits, where its reliable actuation helps meet regulatory compliance for machine safeguarding.

FAQ

What is the difference between normally open (NO) and normally closed (NC) reed switches?

A normally open (NO) reed switch remains open until a magnetic field is applied, at which point the contacts close. This is ideal for detecting the presence of a magnet or the position of a moving part. A normally closed (NC) switch does the opposite, staying closed until a magnetic field forces it open.

Can the D‑A93 be used with AC voltage?

The D‑A93 is specified for DC operation between 10 and 30 V. While reed switches can technically handle AC, using this model with AC may lead to reduced reliability and is not recommended for critical applications.

How do I determine the correct mounting orientation for the sensor?

Mount the reed switch so that the magnetic pole of the target (such as a piston rod magnet) aligns with the center of the glass envelope. This ensures the strongest magnetic field interaction and reliable actuation. The sensor’s flat side should face the magnet for optimal performance.

Is the sensor suitable for high‑temperature environments?

The Baomain D‑A93 is rated for typical industrial temperature ranges up to 85 °C. For applications requiring higher temperature tolerance, a specialized high‑temperature reed switch should be selected.

What warranty does Baomain provide for this product?

Baomain offers a one‑year limited warranty covering manufacturing defects. Should any issue arise within this period, contact our support team for a replacement or repair.
