Notes: 1) The data shown above are initial values.
          2) Equivalent to the max. initial contact resistance is 50m¥Ø (at 1A 24VDC), and measured
              when coil is energized with 100% nominal voltage at 25°C.
          3) When requiring other nominal voltage, special order allowed.

Notice
1. Relay is on the "set" status when being released from stock, with the consideration of shock risen
    from transit and relay mounting, relay would be changed to "reset" status, therefore,
    when application (connecting the power supply), please reset the relay to "set" or "reset" status
    on request.
2. In order to maintain "set" or "reset" status, energized voltage to coil should reach the rated
    voltage, impulse width should be 5 times more than "set" or "reset" time. Do not energize voltage
    to "set" coil and "reset" coil simultaneously. And also long energized time (more than 1 min)
    should be avoided.
3. The terminals of relay without twisted copper wire can not be tin-soldered, can not be moved
    willfully, more over two terminals can not be fixed at the same time.

4. Ordering Code

Notes: 1) When ordering sensitive type, please specify the exact coil power.
            2) HT4 is an environmental friendly product.
