Designed for about one million pressure cycles at 500 bar: high pressure resistant sensors IMP High Pressure

Extreme durability and longevity distinguish the high pressure-resistant inductive proximity sensors of SICK’s IMP High Pressure product family. High-performance materials, the special design structure, as well as state-of-the-art ASIC technology from SICK make them 50 times as stable as comparable proximity sensors.

With these features, they achieve an expected service life of about one million pressure cycles. This is ideal for very long maintenance-free and replacement-free use in hydraulic cylinders and components, as employed, among others, in machine tools, water jet cutting facilities, commercial vehicles, or construction equipment.

Ideally suited for “situations under pressure”

The IMP High Pressure inductive sensors are designed for process pressures up to 500 bar and due to a variety of measures, they are very well suited for “situations under pressure.” The rugged stainless steel housing, the active surface made of high-performance ceramics, as well as SICK’s ASIC technology for increased sensing distances permit extended space between the active sensing face and the core set, thus allowing placement of the power electronics outside of the pressure area. All of this combined endows the IMP High Pressure sensors with unequaled extreme durability. End customers benefit from this extended service life: IMP High Pressure sensors can reliably avoid the major time and expense accompanying every replacement of less durable sensors, including draining the hydraulic fluid and lost operating time of the machine.

Complete product family with designs ranging from M5 to M14

No matter whether used for end position control on hydraulic cylinders or for monitoring space-critical valve positions, the portfolio of IMP High Pressure devices from SICK provides the suitable sensor for any task. Designs from M5 to M8, M12 and all the way to M14 – all of them featuring an IP 68 enclosure rating on the active sensing face and pressure resistance of 500 bar – leave hardly anything to be desired. Sensing distances of up to 3 mm in flush installation as well as three- and four-wire output stages complete the product range. In addition, the majority of IMP High Pressure sensors are already specified as standard for a temperature range of –25 °C to +100 °C.

“Performance under pressure” – no problem for the high pressure-resistant IMP High Pressure proximity sensors from SICK.
