1) Suitable reflectors for laser photoelectric reflex switches: We recommend our

“F” reflectors with micro triple structure or DG reflector tape for short distances

up to 5 m and our standard reflectors for ranges > 5 m (also see the accessories;

reflectors for VL 18 L)

2) Average service life 100,000 h at TA = +25 °C

3) Controll input C – L.ON/D.ON and – external Teach-in

C = open: light-switching L.ON

C = + VS: dark-switching D.ON

C = 0 V: Sensitivity setting per “external Teach-in”

4) Limit values

5) May not exceed or fall short of VS tolerances

6) Without load

7) Signal transit time with resistive load

8) With light/dark ratio 1:1

9) Reference voltage 50 V

10) A =VS connections reverse-polarity protected

B = Inputs and outputs reverse-polarity protected

C = Interference pulse suppression

D= Outputs overload and short-circuit protected
