Attention:The operating distance may vary depending on the background material and installation situation. (Only in combination with actuator CES-A-BBA, CES-A-BCA) Typical operating distance For a side approach direction for the actuator and safety switch, a minimum distance of s = 4 mm must be maintained so that the operating distance of the side lobes is not entered. (Only in combination with actuator CES-A-BPA) Typical operating distance For a side approach direction for the actuator and safety switch, a minimum distance of s = 6 mm must be maintained so that the operating distance of the side lobes is not entered.
