Detailed instructions
 
Photoelectric yarn sensor is a kind of high precision, non-contact photoelectric weft sensor, which is suitable for winding drum, twisting thread, yarn blending and fiber deformation. Photoelectric yarn sensor is a kind of easy to use, simple installation of broken wire sensor.
Basical functions:
The photoelectric weft sensor can detect the running (linear, reciprocating and circular) of various kinds of spinning on the spinning machine. When the spinning stops or breaks, the photoelectric type can inform the automatic control system of the spinning machine in time. According to the actual situation (by the type of the spinning machine).
 
The weft sensor can directly drive the automatic yarn cutter connected with itself to cut off the weft at the corresponding position. Control signal can also be sent to automatically stop the corresponding spinning machine working position.
 
In the alarm state, the photoelectric type is used to warn the field operator with the flashing signal of the led.
Opreating principle:
 
The photoelectric yarn sensor detection head can measure the operation of the spinning in the infrared beam, and judge the working condition of the spinning according to the variation of the voltage caused by the displacement.
 
The measurement accuracy of photoelectric yarn sensor will be reduced due to the interference of external light source and other adverse working environment.
 
The photoelectric yarn sensor has high detection capability, and can detect the yarn weft of 0.02mm.
 
Safety application instructions: it is absolutely necessary to avoid reverse connection or short circuit contact of equipment interface lines. The photoelectric yarn sensor has the capability of electromagnetic protection and can bear voltage shock over 1kv.
Q:  What's your warranty ? How about the quality of your sensors ?
A: 18  months .
  We have the certification of CE,RoHS.Our sensors can replace many famous brand sensors(BALLUFF,IFM,P+F,TURCK,OMRON,SICK,Contrinex,Schneider,KEYENCE,
BANNER,BAUMER,AUTONICS,etc) You can provide us the date sheet and we check whether can produce.
 
Q:  Do you have different style ?
A: We produce our own brand sensor(KJT),also provide OEM + ODM service.
 
Q:  How can we become your sale distributor ?
A: If you can sell our products USD 5,000 to USD 60,000 per year,you could be one of our distributors in your city or area.We have price protection policy in every area.

Q: If i want to release order, what's the payment method you accept ?
A: We accept T/T, Paypal, Western union, L/C.
 
Q: If i want to release order, what's the process?
A: Thanks. You can send inquiry to us or send us by email, we will reply within 12 hrs.
 
Q: Could KJT provide technology support?
A:  We're in this field more than 10 years. If there's any problem, please contact with us,we'll provide suggestion from our engineer to help you solve problem.
 
Q:When you use KJT's photoelectric sensor and inductive proximity sensor, the following subject should be noticed: 
A: Ensure the working voltage is 10-30 V DC or 90-250 AC.
Required the sensing distance and the material of detecting objects.
For photoelectric sensor ensure it is available through beam and reflection.
Ensure it is NPN or PNP output.

Q:  How can I get a sample ?
A: If you need one sample for checking-up,we will provide one free sample for one type sensor(same data sheet) for you, .but we do not carry the freight charge.If we have no this type sample in stock,we could produce it for you.
