The new ZB0050/1 safety rope pull switches from ifm electronic can detect safety-related switching where large danger areas have to be secured and where housings or covers are not possible. Safety rope pull switches are commonly used as a manual safeguard for long distance applications such as conveyor systems. With long coverage spans, rope pull switches eliminate the need for numerous E-stop buttons, reducing installation time and costs. Emergency stop equipment protects personnel in danger.
Pulling the tensioned rope or rope breakage activates the safety rope emergency stop switch. Housed in die-cast aluminium, the switches meet IP67 protection requirements. They have an integrated E-stop with a blue reset button, a tension indicator and long rope spans of up to 250 metres. With four NC safety contacts and two NO auxiliary contacts, the switches are vibration tolerant and the LED function display indicates healthy operation or error conditions.
The rope pull switches meet the requirements of EN ISO 13850, IEC/ EN 60947-5-1 and IEC / EN 60947-5-5 and they can be used in applications up to performance level e according to EN ISO 13849-1. Various accessories are available, such as rope tension kits, safety springs, pulleys, AS-i Safety at Work PCB, M12 adapter plugs and cable glands.
