Product Description

The Keyence EZ-8M is a compact, shielded inductive proximity sensor designed for precise detection of ferrous metals within a 1.5 mm sensing range. Encased in a durable M8 threaded stainless steel housing (SUS303), it offers robust protection with an IP67 rating, making it suitable for harsh industrial environments. This sensor operates on a 12 to 24 VDC power supply and features an NPN open collector output capable of handling up to 100 mA, with a maximum residual voltage of 1 V. Its high response frequency of 800 Hz ensures rapid detection, while its wide operating temperature range of -25°C to +80°C accommodates various applications.
