Description
Product Overview
The Megatronix MGT magnetic reed switch is engineered for high‑reliability alarm and security applications across a wide range of industrial environments. Constructed from a sealed glass envelope that houses a pair of ferromagnetic reeds, the switch activates when a magnetic field is applied, providing a clean, contact‑less operation that eliminates wear and arcing. The device is offered in two configurations—normally open (N O) and normally closed (N C)—allowing engineers to select the appropriate logic for closed‑loop or open‑loop circuit designs. Rated for a maximum of 20 V DC at 0.5 A (10 W) and 120 V AC at 0.08 A, the switch meets demanding voltage and current specifications while maintaining a low power footprint. Its SPST (single pole, single throw) layout simplifies wiring, and the compact form factor fits easily into tight panel spaces. The robust construction, combined with a proven magnetic actuation principle, ensures consistent performance even in harsh temperature ranges and vibration‑prone installations.
Usage
Designed for versatility, the Megatronix MGT reed switch excels in a variety of industrial scenarios. In automated manufacturing lines, it can serve as a safety interlock, detecting door closures or guard positions to prevent equipment operation when access panels are open. In HVAC systems, the switch monitors damper positions, providing feedback to control units for precise airflow regulation. The sensor is also ideal for security alarm panels, where its magnetic actuation offers a tamper‑resistant method to detect window or door breaches without the need for mechanical levers. Because the device operates without external power to the sensing element, it can be integrated into low‑voltage control circuits, battery‑backed emergency systems, and remote monitoring stations where power conservation is critical. Its ability to handle both AC and DC loads makes it suitable for power‑distribution monitoring, motor protection, and even marine applications where corrosion‑resistant sealing is essential.

FAQ
What is the difference between the N O and N C versions?
The N O (normally open) version remains open until a magnetic field is applied, at which point it closes and allows current to flow. The N C (normally closed) version stays closed until the magnetic field is present, then it opens. Selecting the appropriate type depends on whether you need the circuit to be active or inactive when the sensor is not magnetized.
Can the switch be used in high‑temperature environments?
Yes. The sealed glass envelope and internal reed materials are rated for operation up to 85 °C (185 °F). For applications requiring higher temperature tolerance, Megatronix offers variants with extended temperature ratings upon request.
Is the switch compatible with both AC and DC power sources?
Absolutely. The MGT model is designed to handle 20 V DC at 0.5 A and 120 V AC at 0.08 A, making it suitable for mixed‑signal control panels that incorporate both alternating and direct current circuits.
How do I determine the correct mounting orientation?
The switch is non‑polarized, meaning it can be mounted in any orientation without affecting performance. However, for optimal magnetic field exposure, position the sensor so that the magnetic source approaches the flat side of the glass envelope directly.
What warranty does Megatronix provide?
Megatronix offers a standard one‑year limited warranty covering manufacturing defects. Extended warranty options are available for bulk orders and can be arranged through our sales representatives.
