¹⁾ Reflective tape REF-AC1000.
²⁾ To ensure reliable operation, we recommend using REF-AC1000 reflective tape or reflective-tap reflectors such as P41F, PLV14-A, PLH25-M12, or PLH25-D12. Reflectors with large-scale triple structures must only be used if deemed suitable for the application.

¹⁾ Limit values when operated in short-circuit protected network: max. 8 A.
²⁾ May not exceed or fall below U_v tolerances.
³⁾ Without load.
⁴⁾ Q = light switching.
⁵⁾ Signal transit time with resistive load.
⁶⁾ With light/dark ratio 1:1.
⁷⁾ A = V_S connections reverse-polarity protected.
⁸⁾ B = inputs and output reverse-polarity protected.
⁹⁾ C = interference suppression.
¹⁰⁾ As of T_a = 50 °C, a max. supply voltage V_max. = 24 V and a max. load current I_max. = 50 mA is permitted.
¹¹⁾ Operation below Tu –10 °C is possible if the sensor is already switched on at Tu > –10 °C, then cools down, and the supply voltage is subsequently not switched off. Switching on below Tu –10 °C is not permissible.
