Reed Relay JD2912 Type Reed relay Application Electromagnetic switching Model JD2912 Overview The JD2912 is an electromagnetic reed relay that uses a magnetic field to actuate reed contacts. It provides an isolated switch between the control circuit and the load, suitable for signal and control applications in electromagnetic environments. The design emphasizes reliability, compactness, and repeatable performance. Key benefits Electrical isolation: galvanic isolation between the coil and the switched circuit Fast switching: suitable for timesensitive signaling in control and instrumentation Compact form: small footprint for spaceconstrained designs Sealed contacts: reduces exposure to contaminants and supports reliable operation Low drive power: actuates with modest coil current relative to output requirements Consistent performance: designed for repeatable switching in electromagnetic applications Attributes Function: provides an isolated, electromagnetic switch for controlling circuits Compatibility: works with standard control electronics and lowlevel drive signals commonly used in automation and instrumentation Size: compact form factor suitable for compact assemblies (specific dimensions not provided) Material: sealed reed contact assembly within a protective envelope (design optimized for reliability) Performance: delivers reliable switching with minimal interference between coil and contacts Applications and use scenarios In a PLCbased control panel to switch small signal lines while keeping the control network isolated from the load circuit In test equipment to route measurement signals without introducing controlside interference In compact instrumentation or sensor modules where fast, quiet switching is required and available space is limited
