The IFM IE5391 Inductive Proximity Sensor is a compact, high-performance inductive sensor engineered for reliable, non-contact detection of metal objects in demanding industrial environments. Featuring a 4mm sensing range, PNP Normally Open (NO) output, and a durable M8 × 1 threaded housing, it delivers precise and consistent switching performance in factory automation, material handling systems, refrigerated warehouses, mobile equipment, and cooling and lubrication applications.
Designed to operate on a 10–30V DC power supply, the IE5391 incorporates gold-plated contacts, magnetic-field immunity up to 300mT, and Correction Factor K = 1, ensuring the same sensing distance across all common metals. With a 1000Hz switching frequency, reverse polarity, overload, and short-circuit protection, it provides reliable operation in electrically noisy environments. Its rugged construction, vibration and shock resistance, and IP65/IP67 protection make it suitable for harsh industrial conditions.
Features:
- 4mm sensing range for accurate non-contact metal detection
- PNP Normally Open (NO) output for industrial automation systems
- Magnetic-field immune up to 300mT for reliable operation
- Correction Factor K = 1 ensures constant sensing distance on all metals
