The PRFD series cylindrical proximity sensors are available in standard and IO-Link communication models. The sensors feature long sensing distances and full-metal housing and sensor heads made of stainless steel 303. The robust sensors provide high durability and can be applied in diverse environments including food and beverage manufacturing, chemical, and metalworking industries. The status indicator offers users to quickly identify operation status from various angles.
