Product Description
Universal thru-beam sensor, large housing design, 30 m detection range, red light, 25 kHz transmission frequency, light/dark on, DC version, push-pull output, test input, pre-fault output, fixed cable
System components
EmitterLD28-F1/76a/115
ReceiverLV28-F1/82b/110/115
General specifications
Effective detection range0 ... 30 m
Threshold detection range40 m
Light sourceLED
Light typemodulated visible red light , 660 nm
Alignment aidLED red (in receiver lens)
illuminated constantly: beam is interrupted,
flashes: reaching switching point,
off: sufficient stability control
Transmitter frequencyF1 = 25 kHz
Diameter of the light spotapprox. 0.6 m at 30 m
Angle of divergenceEmitter 1.2°,
Receiver 5°
Ambient light limit50000 Lux
Functional safety related parameters
MTTFd620 a
Mission Time (TM)20 a
Diagnostic Coverage (DC)90 %
Indicators/operating means
Operation indicatorLED green
Function indicatorLED yellow:
1. LED lit constantly: signal > 2 x switching point (function reserve)
2. LED flashes: signal between 1 x switching point and 2 x switching point
3. LED off: signal < switching point
Control elementssensitivity adjustment (Adjustment to < 25% of the effective operating range) , Light-on/dark-on changeover switch
Electrical specifications
Operating voltage10 ... 30 V DC
Ripple10 %
No-load supply currentEmitter: ≤ 50 mA
Receiver: ≤ 35 mA
Input
Test inputemitter deactivation at +UB (Imax. < 3 mA at 30 V DC)
Output
Pre-fault indication output1 PNP transistor, short-circuit protected, protected from reverse polarity, open collector, Umax = 30 V DC, Imax = 0.2 A
The output becomes inactive if the signal level has fallen below the function reserve for approx. 10 s (yellow and red LEDs flash).
If the light beam is interrupted four times during this period, the output immediately becomes inactive.
Switching typelight/dark on, switchable
Signal output1 push-pull (4 in 1) output, short-circuit protected, reverse polarity protected
Switching voltagemax. 30 V DC
Switching currentmax. 100 mA
Switching frequency1000 Hz
Response time0.5 ms

Function: LD28/LV28-F1/76a/82b/110/115

The series 28 family of sensors can be universally used. It has a large range of models that allows it to be integrated into any automation environment. The sensors are contained in sturdy water resistant plastic housings with multiple fastening options and scratch resistant optical cover. Features such as a timer function, and functions including a light/dark switch, sensitivity adjuster and highly visible status LEDs make for less effort on the part of the user and streamline installation, setup and operation. Just about any task associated with positioning, moving, conveying and monitoring can be accomplished with these sensors.
