FOCUSENS Epoxy Encapsulated Normally Open Window Contact 12v 24v DC Magnetic NO Reed Switch

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Magnetic Field Detection: Designed to detect the presence/absence of a magnetic field, enabling status monitoring of doors, lids, or other magnetic components.
  • Switch Control: Triggers an electrical switch output (12V/24V DC) to activate connected systems, such as alarms, lighting, or automation processes.

Key features

  • 1. Durable Epoxy Encapsulated Construction

    • With an epoxy encapsulated ABS plastic body, ensure reliable performance in harsh industrial environments. The corrosion-resistant and chemical-resistant material extends lifespan compared to standard plastic sensors*, offering robust protection against moisture and contaminants.

  • 2. Flexible Mounting Design for Versatile Installation

    • With adjustable mounting holes and a compact rectangular form, install the sensor in diverse orientations and tight spaces. This design adapts to varied industrial setups, unlike fixed-mount sensors limited to specific configurations.

  • 3. Wide Voltage Compatibility for Seamless Integration

    • With 12V/24V DC compatibility and inductive sensing technology, operate reliably across industrial systems. The magnetic reed switch delivers precise on/off control, outperforming traditional mechanical switches prone to wear in continuous use*.

  • 4. Industrial-Grade Reliability for Continuous Operation

    • Designed for industrial automation, the sensor maintains stable switching transducer output in demanding scenarios. Its magnetic detection capability ensures uninterrupted monitoring of machinery or equipment status, ideal for 24/7 commercial use versus home-grade alternatives*.

  • 5. Comprehensive Compliance with Global Standards

    • With RoHS certification and EPR compliance (Germany/France WEEE/Packing), meet stringent environmental and safety regulations. This ensures broader market acceptance compared to non-certified competitors.
