• Safety switch with integrated evaluation electronics
• No series connection

Approach direction Can be adjusted in 90° steps Short circuit monitoring The switch generates its own clock signal on the output cables OA/OB. Pay attention to this aspect when connecting to control systems and relays. Each actuator is unique. The switch detects only taught-in actuators. Additional actuators can be taught in. Only the last actuator taught in is detected. Category according to EN 13849-1 Due to two redundantly designed semiconductor outputs (safety outputs) with internal monitoring suitable for:

• Category 4 / PL e according to EN 13849-1

Important: To achieve the stated category in accordance with EN ISO 13849-1, both safety outputs (OA and OB) must be evaluated. LED indicator

Typical operating distance With actuator CES-A-BBA and CES-A-BCA 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. With actuator CES-A-BPA 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. With actuator CES-A-BRN 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.
