Robust full-metal sensors for diverse applications

June 2018 Sensors & Transducers

Autonics has released the new PRF series full-metal inductive proximity sensors with stainless steel housing and sensor heads. The robust sensors are highly resistant to deformation and corrosion and can be applied in diverse environments including food and beverage manufacturing, and the chemical and metalworking industries.

The sensors feature high resistance to impact and wear caused by contact with workpieces or wire brushes, and also provide reduced risk of malfunction caused by aluminium chips. With a specialised sensor IC, the PRF series also offers excellent noise immunity and come standard with a built-in surge protection circuit and overcurrent protection. With the 360 ring type status indicators, users can easily identify operation status from various angles. The robust oil-resistant cable allows the sensors to be installed in environments with hydraulic fluids or cutting fluids, and the IP67 rated structure allows stable and error-free operation even in wet or dusty environments. The series is available in 12, 18 and 30 mm diameter sizes, and are offered in cable and cable connector types. Long sensing distance type models are also available.

The PRFA and PRFDA series are spatter-resistant models, with PTFE coating to reduce the risk of malfunction caused by welding spatter. The non- stick PTFE coating prevents welding spatter from sticking on to the sensors which minimises the risk of malfunctions during welding applications. These sensors offer high flexibility in various metalworking applications.

The full-metal type sensors offer high usage in various applications. The stainless steel body minimises the chance of bacteria spreading, and the unibody design prevents cleaning agents and germicides from entering the sensor body, making it perfect for food and beverage applications. The sensors are also ideal for chemical applications with high resistance to deformation and corrosion.
