Overcurrent protection: Use of Interface Unit (CL-1F)
In areas with unstable current, there is a risk of damage to the internal contacts due to excessive inrush current or overcurrent.
Please use a relay (CL-1F) as a set to protect the sensor’s contact before use. We have received inquiries about problems caused by overcurrent, especially in areas such as India.

By attaching the interface unit to the control panel in advance, it plays the role of the sensor’s contact protection circuit in environments where there is a risk of overcurrent.
Remark: Socket for interface unit mounting is not included. Use OMRON MY2 relay socket or terminal block socket.
