MAEDA KOKI MKCM Type Water 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, by a metal protective cover possibility of the damage by shocks from the outside. It reduce it.
The installation direction does not matter. The posture when I attach it because it use a spring inside.
It look up and look down and can perform sideways-facing freely.

Model
MKCM □* –□TW-OFF(ON)

Operation flow quantity of the switch
□L/min

An example: Operation flow quantity 1L/min of the MKCM20-2TW-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)

Fluid		Water
Operation flow quantity		Please appoint it with the above, a flow quantity level in the designated range of the operation flow quantity.
Connection		Rc internal thread	Change to R screw The combination with the R screw is possible, too.
Heat-resistant temperature		A maximum of 60 degrees Celsius	I can produce the heat-resistant specifications (a maximum of 100 degrees Celsius), too.
Withstand pressure		1MPa	I can produce the withstand pressure specifications (up to 5MPa), too.
The use of maximum voltage		DC, AC 300V
Use of maximum electric current		DC, AC 0.5A
Point of contact capacity		50VA
Materials	Transparent pipe	Acrylic	The heat resistance, withstand pressure specifications product becomes brass pipe (C3604). The heat resistance, withstand pressure specifications product cannot see the float.
	Protective cover	BC (gunmetal)	I can produce the product made in aluminum, too.
	Coupling	C3604 (brass)	I can produce the product made in SUS, too.
	Spring	SUS304	–
	Float with magnet	Acrylic or Nylon	–
	O ring	Nitrile rubber	Heat resistance, the withstand pressure specifications become the fluorine rubber.
	Lead switch	Marketing product	–
	Lead (authentic sample 200mm)	Marketing product	Designation of the length of the lead, The change to cab tire cord is possible, too.

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

So that, as for the flow switch, an overcurrent does not flow in a lead switch for causes such as the ground connection defectiveness. Please be careful about connection.
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)
