ifm presents new inductive proximity sensors in full metal housings in three sizes for safety applications: M12, M18 and M30 with a housing length of 60 mm. For use in mobile machinery, they are designed for a temperature range of -40°C to +85°C; for food applications, the temperature range is -25°C to +100°C. There are six different types of the new sensors, which are suitable for applications up to SIL-2 according to IEC 61508 or PL d according to EN ISO 13849. The connection technology is based on well-proven M12 connectors.
Mobile machine monitoring
The robust full metal housing effectively protects the sensor against harsh environmental conditions. Shocks and vibrations do not pose a problem. Unlike models with a plastic front, there are no problems with permeation through the material. This makes the sensors extremely durable and minimises the risk of malfunction.
A typical application in the food industry is the monitoring of manholes in tanks, silos and other large containers. Access to these must be reliably monitored to prevent hazards to personnel. Manholes must also be reliably monitored when mobile machinery is in operation. This applies, for example, to debris hoppers in road sweepers. Another application is the monitoring of jibs on mobile cranes on trucks. The crane is only allowed to lift loads when the outriggers are extended and lowered. The new full metal inductive proximity sensors are ideal for this and many other safety applications.
