System elements
Emitter		LD28-LAS-F1-7675
Receiver		LV28-LAS-F1-7675/47
Overall specifications
Operational sensing range		0 ... 120 m
detection range threshold		150 m
illumination source		laser diode
Illumination type		modulated red light in the visible spectrum
Laser specified ratings
	Note	LASER LIGHT , DO NOT STARE INTO BEAM
	Laser category	2
	Wavelength	650 nm
	Beam spreading	< 4 mrad
	pulse duration	20 µs
	Repetition frequency	25 kHz
	maximum pulse energy	18 nJ
Alignment tool		Red LED (within receiver lens) constantly illuminated: beam is interrupted, flashes: achieving switching threshold, off: adequate operational margin
Size of the illumination spot		Approximately 20 mm at 5 m, roughly 75 mm x 300 mm at 70 m horizontally relative to the housing axis
angle of opening		Emitter: 0.23 ° Transducer: 5 °
Ambient light threshold		50000 Lux
Parameters related to functional safety
MTTF_d		540 a
task duration (T_M)		20 a
Diagnostic Range (DC)		90 %
Indicators/operation controls
Operational status indicator		LED green
operation indicator		Yellow indicator LED: 1. LED continuously illuminated: signal > 2 x switching threshold (functioning margin) 2. LED blinks: signal between 1 x switching threshold and 2 x switching threshold 3. LED off: signal < threshold point
control components		Sensitivity calibration (Calibration to < 25% of the usable functioning range), Light-on/dark-on toggle switch
Electrical parameters
Operational voltage		10 ... 30 V DC
Ripple		10 %
No-load input current		Emitter: = 55 mA Transducer: = 40 mA
Input
Verification input		emitter shutdown at +U_B
Output
Stability fault indication output		1 PNP transistor with short-circuit protection, reverse-polarity protection, open collector configuration, Umax = 30 V DC, Imax = 0.2 A The output is rendered inactive if the signal level drops below the functioning reserve for approximately 10 seconds (yellow and red LEDs are flashing) If the light beam is disrupted four times within this timeframe, the output will deactivate immediately
