General Description


The AXICOM IM series 2 form C slim-sized signal relays come in different performance types and variable terminals structures for specific instrumentation requirements (take reference from the product code definition table below). The IM series supports 4G telecom/signal/switching transition with switching power of 60W/62.5VA. Besides, its rated coil power is relatively low, which indicates more current should be taken to switch successfully. What’s more, it has a high shock resistance mechanism, making it rather reliable in the harsh operating environments.

    Where to Use IM03GR


This signal relay family has a wide range of application aspects including Telecommunication, access and transmission equipment, optical network terminals, modems, Thermostat controls, fire and security equipment, consumer electronics, industrial control, medical equipment, HVAC and more.



                                   How to Use IM03GR





The above are the main components of surface mount signal relays. The coil is secondary molded, resulting in excellent insulation between the coil and the contact while remaining compact.


This simplified circuit diagram shows how IM03GR is used as a high-efficiency switch that control open/closed status of the circuit. It can operate with a maximum 220V DC voltage and 250V AC voltage supply.


User Guidelines

The diagram illustrates the switching resistive load changing “cliff” (which generally indicates the contact ratings). The shadowed area depicted recommended application range of the device. Make sure to select the correct type of relay for the electrical load you’re managing, as well as one that matches your durability requirements.






Although the relay will operate if the applied voltage is greater than the operational voltage, it is necessary to provide only the rated voltage to the coil to account for variations in coil resistance, etc., caused by variances in power supply type, voltage fluctuations, and temperature increases. Also, exercise caution because if the voltage used exceeds the maximum that may be applied, issues such as layer shorts and coil burnout may occur. Precautions for coil input are listed in the section below. In order to avoid issues, please refer to it.
