Allen Bradley Inductive Proximity Sensor, 20mm Detection Range, 200mA Switching Current - 871TM-N20NP18-D4
Monitor the presence of ferrous and non-ferrous metal objects using this proximity sensor from Rockwell Automation's Allen Bradley range. As it's an inductive sensor, it works by generating an electromagnetic field that reacts to the presence of metals within a set detection range. This means that it doesn't need to make physical contact with the target, reducing the risk of mechanical wear and ensuring long-lasting performance. For enhanced ease of use, the sensor comes with an IO-Link interface that lets you connect it to your control system for data processing.
IP69K (ingress protection) rating for protection against dust and hot, high-pressure water jets
Durable stainless steel housing is resistant to impact and corrosion for an extended service life in harsh environments
Broad operating temperature range of -25°C to +70°C for safe industrial use
Standards and Certifications
CE (Conformitè Europëenne)
cULus (Underwriters' Laboratories in Canada and the US)
What are ferrous metals?
Ferrous metals are metals containing iron. They have excellent tensile strength and magnetic properties. Common ferrous metals include steel, cast iron and wrought iron.
