Cable float level switch

MDCable float level switch

(Large quantity of spot goods, wholesale MD-UK221 float level switch, all using high-quality waterproof cables to ensure cable length and quality. The body is made of raw materials and molded in one go. The specification of ordinary cables is less than 0.3. Our company uses 0.5 core copper wire, which has a more exquisite appearance. Welcome to purchase, try, and purchase in large quantities.)
1、 Product Overview:
MD float switch uses micro switches or mercury switches as contact parts. When the cable float rises at a certain angle from the heavy hammer as the origin (usually the micro switch rises at an angle of 28 °± 2 ° and the mercury switch rises at an angle of 10 °± 2 °), the switch will output an ON or OFF signal. CF-P type is formed by plastic injection molding, so its structure is sturdy, its performance is stable and reliable, it is non-toxic, corrosion-resistant, easy to install, and inexpensive. It has the effect of controlling long-distance multi-point control, submersible pumps, fluctuating liquids or liquids with impurities. Ordinary liquids can also be used.
The cable length can be customized to any length. The CF-S type is a metal float level switch with mercury switch as the contact part. Its characteristic is high temperature resistance, and the cable adopts high flexibility cable, which is durable.
• Use a micro switch for contact output, with a contact capacity of 10A/250VAC, which can directly start motor equipment • European standard (HAR) rubber cable, weather resistance, long service life • Simple structure, no maintenance required, can be used for both sewage and water purification
Any length of cable can be customized
2、 Performance characteristics:
The design and strict manufacturing process provide a reliable guarantee for product quality.
The shell is made of engineering plastic, which has high mechanical strength and good sealing performance.
The cable is made of special materials that are resistant to oil, acid, and alkali, and have better corrosion resistance.
Simple structure and reliable performance. Output stable and reliable "on" and "off" switch control signals without any misoperation, with high reliability.
Easy to install and debug, the positioning weight can be moved up and down to freely adjust the Huai surface control range.

4、 The installation method of heavy hammer
1. After threading the wire of the float switch through the concave circular pole L at the center of the heavy hammer, gently push the heavy hammer to make the plastic ring embedded above the circular hole fall off due to the pushing force of the wire head. If necessary, you can also use a screwdriver to remove this plastic ring, and then put the detached plastic ring on the cable to set the water level as you want with a weight hammer.
2. Gently push the hammer to pull out the cable until the center of the hammer grips the plastic ring. **As long as the heavy hammer is lightly fastened in the plastic ring, it will not slip off. If the plastic ring is damaged or lost, it can be replaced by fastening the same light bare copper wire into the cable.
The heavy hammer is a required accessory. Please pull the cable directly to the control box and avoid using intermediate joints as much as possible. If there is a joint due to necessity, never immerse the cable joint in water.

5、 Installation precautions

1. ① Use black and blue wires: When the float is at the upper liquid level, the contact is not connected. When the float is at the lower liquid level, the contact is in a connected state.
② Use black and brown wires: When the float is at the upper liquid level, the contact is in a connected state. When the float is at the lower liquid level, the contact point is not connected.
2. The length of the float action a must be less than the distance A between the groove wall and the cable, and the float control minimum water level d must be greater than the water level D.
3. The installation position should be kept at an appropriate distance from the inlet to prevent the float switch from being sucked in by the inlet.
4. The installation position should be kept at an appropriate distance from the inlet to avoid incorrect induction caused by water impact. If it cannot be avoided, protective pipes can be installed to improve.
