Ambient temperature-40 ... 60 В°C (-40 ... 140 В°F)
Housing width25.8 mm
Switching currentmax. 200 mA
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
Protection classII, rated insulation voltage 250 V AC with pollution degree 1-2 according to IEC 60664-1 Output circuit basis insulation of input circuit according to EN 50178, rated insulation voltage 250 V AC Caution!
The protection class 2 is only valid when the terminal compartment is closed.
Light typemodulated visible red light , 660 nm
Threshold detection range40 m

Storage temperature-40 ... 75 В°C (-40 ... 167 В°F)
Control elementssensitivity adjustment (Adjustment to < 25% of the effective operating range) , Light-on/dark-on changeover switch
Housing height88 mm
Effective detection range0 ... 30 m
Alignment aidLED red (in receiver lens)
illuminated constantly: beam is interrupted,
flashes: reaching switching point,
off: sufficient stability control
Connectionterminal compartment with 8 spring-loaded terminals for wire cross section 0.5 ... 1.5 mm2 , Insulation stripping 7.5 ... 8.5 mm , M16 x 1.5 cable gland
Response time0.5 ms
CCC approvalCCC approval / marking not required for products rated 36 V
Light sourceLED
Product standardEN 60947-5-2
Operation indicatorLED green
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.
Transmitter frequencyF1 = 25 kHz
Mission Time (TM)20 a
Degree of protectionIP67
MTTFd620 a
Timer functionON delay (GAN), OFF delay (GAB), one shot (IAB), ON delay-one shot (GAN-IAB), ON delay-OFF delay (GAN-GAB), programmable
adjustment interval 0.02 s ... 1 s
