Mechanical and electrical characteristics
Supply voltage DC 10 V … DC 30 V 1)
residual ripple < 5 V pp 2) Current consumption 30 mA 3) Switching output PNP 4) Switch function Complementary Switching type Light on/dark on mode 4) Output current I max. ≤ 100mA Response time ≤ 0.5 ms 5) Switching frequency 1,000Hz 6) Connection type M8 male connector, 4 poles Protection switches At 7) B 8) C 9) Protection class III Weight 100g Case material Plastic, Novodur Material, optics Plastic, PMMA Degree of protection IP66 IP67 Operating ambient temperature –10 °C ... +50 °C Advanced operating room temperature –30 °C ... +55 °C 10) 11) Ambient storage temperature –30 °C ... +70 °C 1) Limit values, short-circuit-proof mains operation up to 8 A. 2) U v Cannot go beyond or below the tolerance values. 3) Without load. 4) Q = light on operation. 5) Signal duration with ohmic load. 6) With light/dark ratio 1:1. 7) A = U V connections protected against polarity reversal. 8) B = inputs and outputs protected against reverse polarity. 9) C = Interference pulse suppression. 10) From T u = 50 °C, a max. V max = 24 V and a maximum output current I max = 50 mA. 11) Operation below Tu = –10 °C is possible if the sensor is activated at a temperature Tu > -10 °C, then cooled down and is no longer disconnected from the supply voltage. Activation at temperatures below Tu = –10 °C is not permitted.
