AJ8 Switches with Trip Function Upgraded Type

AJ8 Switches with trip function upgraded type Cautions For Use

1.Operating voltage application time

If the rated voltage is applied to the coil for more than 10 seconds or the maximum voltage is applied for more than 1 second, coil performance may deteriorate.

2.The shape of the mounting panel should be as recommended in the dimensions diagram.

Please contact us if you are considering using a panel of other than the recommended size and shape.

3.The mounting panel should be made of SPCC. If a different material is used, its adhesion to the switch unit may not be as strong. Check this with actual application necessary.

4.Note that the actuator could come off from the switch housing if 19.6N or more of force is applied to the side of the actuator.

5.Regarding fastening lead wires to terminals

  • 1.When connecting the .250 Quick connect terminals, use a .250 receptacle and insert the terminals straight in.
    If you insert them at an angle, the terminals could catch on the opening and will require greater insertion force.
  • 2.The coil terminals have specific polarities. Make sure you connect them correctly.
  • 3.Use a receptacle that is compliant with JIS C 2809.
    In addition, there is some deviation regarding the insertion force depending on the model used from different manufacturers, so the insertion force should be checked under actual conditions.
  • 4.Use TE Connectivity Ltd.’s CT connector for the coil terminals.

6.Because special receptacle terminals are used for the contact terminals and the common terminals, do not attempt to solder them. Doing so could melt plastic components and otherwise harm the performance of the switch.

7.The terminals should be connected in such a way that they are not under constant stress from the connecting wires.

8.Take care not to drop the product as it may impair performance.

9.Resistance to chemicals

To clean the switch unit, use a neutral detergent diluted with water.
Do not use acidic or alkaline solvents as they may damage the switch.
Furthermore, be careful not to get any of the detergent solution inside of the switch while cleaning it.

10.This product is not hermetically sealed, so its performance could deteriorate under certain ambient conditions. Avoid using and storing these switches in a location where they will be exposed to corrosive gases, silicon, or high dust levels, all of which can have an adverse effect on the contacts. In addition, because these switches contain permanent magnets, avoid using and storing these switches in a location where metallic dust, etc., is present.

11.When these switches are used with weak currents of 500mA or less, a layer of material on the surface of the contacts may cause contact instability. Check and evaluate this possibility before using these switches under such conditions.

12.When using an ON-OFF type switch with no (|O) indication on the actuator, the "OFF" position should be indicated on the set in which the switch is installed.

13.To assure reliability, check the switch under actual loading conditions. Avoid any situation that may adversely affect switching performance.
