Optical detectors "BQ" of moving yarns
3. Technical Data
Operating and storage conditions:
Accurate and failure-free operation is guaranteed in case that the following conditions are observed:
- Operating environment temperature 0 – 45 °C
- Air pressure 85 – 106 kPa
- Relative humidity is max. 95% when absolute humidity of environment should not exceed 40 g/m3
- Minimal distance from a light source under operation (fluorescent tube 40W) is 1 metre.
- Sensor should be stored in dry, clean, and ventilated rooms without aggressive gasses; at the temperature from – 20 °C to +55 °C and at relative humidity from 40% to 85%

Sensor versions according to the output types:
BQx6 – the output element is made by an open collector of transistor (24V/100mA), common GND. At presence of moving yarn, the transistor is connected at GND; HL1 – is not lighting . HL2 - signalling is or is possible at the input IN.
BQx6P - the output element is made by an open emitter of transistor (24V/100mA), common + 24. At presence of moving yarn, the transistor is connected at + 24V; HL1 – is not lighting . HL2 - signalling is or is possible at the input IN .
BQx7 – the output element is made by a relays contact (DC 24V/0.5A, AC 120V/0.5A R ). In your order, it is necessary to state which contacts should be using , i. e.: closing contact, break contact, or change-over contact. HL2 signalling can be common to HL1 or at the input IN.
BQx8 – the output element is made by a tyristor anode (24V/20mA). The tyristor closes (to GND) at the moment in which yarn stops moving, and at the same time the HL1 light starts to flash. HL2 signalling is at the input IN.
BQx8N - the output is the same as at the BQx8. By connecting the input IN to GND, it is possible to shorten the reaction time, whereat HL2 flashes at the rhythm of the moving yarn.
Light Signalling: HL1 flashing red light – signals a yarn break, the moving yarn in the operating area is not present. H2 input IN – might be used to indicate sensor powering, respectively to signal state of place outwards of the machine.
Cable Connection: supply cable of the length L is ended with a connector according to the given specification
