Maeda Koki MKCM Type Oil Signal

Made in Japan
Manufacturer: Maeda Machinery Research Institute Ltd.
Model: MKCM Type

Features

Flow switch
Detects the flow of fluid and turns the switch ON or OFF at the specified flow rate.
*The switch is fixed (the setting cannot be changed later). A flow detector that checks the flow of fluid by the movement of a float inside a transparent tube that
allows you to see the flow of oil at a glance . Comes with a protective cover.
The metal protective cover reduces the possibility of damage from external impacts . No need to worry about the installation direction . A spring is used inside, so the installation position can be freely adjusted, such as upward, downward, or sideways.

Material	Transparent tube	acrylic	Heat-resistant and pressure-resistant products are made of brass tube (C3604). Heat-resistant and pressure-resistant products have a float that cannot be visually inspected.
	Protective cover	BC (gunmetal)	Aluminum versions are also available.
	Fittings	C3604 (Brass)	SUS products are also available.
	spring	SUS304	–
	Magnet included float	Aluminum	–
	O-ring	Nitrile Rubber	Heat and pressure resistant specifications are made of fluororubber.
	Reed switch	Commercial goods	–
	Lead wire (standard 200mm)	Commercial goods	You can also specify the length of the lead wire and change to a cab-tire cord.

Reed switches are magnetic switches, so use them in a place where they will not be affected by magnetic fields.
If there is a magnetic material such as iron near the reed switch, it may cause it to malfunction.

Be careful when wiring the flow switch to prevent overcurrent from flowing through the reed switch due to poor earth wiring etc.
Please use the flow switch as an alarm detector whenever possible.
If you use it in conjunction with other electrical equipment, please take into consideration the effects of malfunction.
The lifespan of the reed switch will be extended if the operating voltage and current are kept as low as possible.
(Normally, the switch can be operated approximately 1 million times under conditions of 100V 0.5A.)

If the temperature or viscosity of the oil changes, the switch may not operate at the set flow rate or the switch operating flow rate
may change.
