Description

The Y213 reed switch utilizes a pair of ferromagnetic reeds sealed within an inert gas-filled glass envelope. When an external magnetic field of sufficient strength is applied, the reeds are magnetically attracted, closing the electrical contact to complete a circuit. Upon removal of the magnetic field, the inherent spring tension of the reeds causes them to separate, opening the circuit. This magnetically actuated, non-contact switching principle offers high reliability and a long operational life with no mechanical wear.

Designed for durability, the hermetically sealed glass construction protects the internal contacts from oxidation, dust, and corrosion, making it suitable for use in demanding environmental conditions. Its compact 45mm total length and minimal power requirements facilitate easy integration into printed circuit boards (PCBs), control panels, and embedded systems for sensing and switching functions.

Key Features

  • Hermetically Sealed Construction: Glass encapsulation provides excellent environmental protection against moisture and contaminants.
  • High Voltage Rating: Capable of switching loads up to 300 VDC, suitable for various control applications.
  • Wide Thermal Tolerance: Stable operation across an extensive temperature range from -50°C to +140°C.
  • Fast Response Time: Features low bounce time (0.25ms) and quick release time (0.35ms) for precise switching.
  • Low Power Consumption: Ideal for battery-powered or energy-efficient sensing systems.
  • Simple Two-Terminal Interface: Easy to wire directly into circuits for magnetic proximity detection.

Applications

  • Door and Window Security Sensors: Integrated into alarm systems to detect opening/closing via a mounted magnet.
  • Liquid Level Sensing: Used with a float magnet in tanks to indicate high or low fluid levels.
  • Reed Relay Coils: Serves as the switching element in low-power signal relays for isolation.
  • Bicycle Speedometers and Tachometers: Detects wheel rotation via a spoke-mounted magnet for speed/distance calculation.
  • Industrial Position Sensing: Monitors the open/closed state of valves, actuators, or mechanical limits in automation.

Frequently Asked Questions

What is the maximum current and voltage this reed switch can handle?

The Y213 reed switch is rated for a maximum switching voltage of 300 VDC and a maximum switching current of 0.55 Amps. It has a contact power rating of 10W. Do not exceed these ratings to ensure reliable operation and prevent contact welding or failure.

How do I wire and use this normally open reed switch?

This is a two-terminal passive component. In its normal state (no magnetic field present), the circuit is open. When a sufficient magnetic field is applied (typically from a permanent magnet), the internal contacts close, completing the circuit between the two leads. Wire it in series with your load and a current-limiting resistor if necessary, ensuring polarity is not a concern for DC operation.

What is the operating temperature range and environmental protection?

The switch operates reliably from -50°C to +140°C. Its hermetically sealed glass envelope provides protection against dust, moisture, and corrosion, making it suitable for use in harsh environments where oxidation or contamination could affect electrical contacts. It is not submersible unless further protected by an external housing.

What are the response time specifications for this switch?

The switch features a bounce time of 0.25 milliseconds and a release time of 0.35 milliseconds. The maximum operating time is 0.45 ms. These fast switching characteristics make it suitable for applications requiring precise timing or high-frequency counting, up to its rated operating frequency of 5 kHz.
