MAEDA KOKI MKCM Type Air Signal

Manufacturer: Maeda Machinery Research Institute Ltd.
Model : MKCM type
Features
- A switch is with flow quantity
- It detect fluid flow and let it is ON, or a switch be off with flow quantity of the designation.
- The switch is rigid (the set point change from a trace is not possible).
- It can see a flow at first sight.
- It is a rheoscope confirming fluid flow by the movement of transparent floats in the jurisdiction.
- With protective cover, it reduce possibility of the damage by shocks from the outside by a metal protective cover.
- The installation direction does not matter.
- An upswing and downward-facing and sideways-facing can perform the posture when they attach it as they use a spring inside freely.

Operation flow quantity of the switch
□L/min |
- An example: Operation flow quantity 30L/min of the MKCM20-2TA-OFF switch
- ※The point of contact method, please appoint OFF method or ON method.
- When OFF method, fluid does not flow; the point of contact OFF (the normal opening A point of contact)
- When ON method, fluid does not flow; the point of contact ON (the normal closing B point of contact)

Flow switch precautions
1. Attention in the magnetic influence
- Please use the lead switch for a switch acting with magnetism at the place that is not affected by the magnetic field.
- When magnetic bodies such as the iron exist in the vicinity of the lead switch, it causes the malfunction.
2. Attention in the electrical connection
- The flow switch, please be careful about connection so that an overcurrent does not flow in a lead switch for causes such as the ground connection defectiveness.
- Please use the flow switch as a warning analyzer if possible.
When you use it in conjunction with other electric apparatuses, please deal with influence when malfunction occurred after consideration enough. - When the use voltage, the use electric current hold it in check as small as possible and use it, the life of the lead switch gets longer.
(usually possible use of approximately 1 million times of switch operation under the 100V0.5A situation)
