Product Description

The IFM Inductive Cylindrical Proximity Sensor (MPN IFS251) is a cylindrical sensor with a built-in connector, featuring an unshielded design, 3 wires, and a 4-pin M12 connector with NC output. It operates on a DC supply voltage rating of 10-30V DC and is not rated for AC supply voltage.

Frequently Asked Questions

What is the IFM IFS251 inductive proximity sensor used for?

The IFM IFS251 inductive proximity sensor detects metallic objects without contact. It is commonly used in industrial automation for position sensing, machine tool monitoring, and conveyor systems. Its unshielded design and NC output suit applications requiring reliable detection in tight spaces.

What are the specifications of the IFM IFS251 sensor?

The IFM IFS251 is an unshielded cylindrical proximity sensor with a built-in M12 4-pin connector and NC output. It operates on 10-30V DC (not rated for AC) and uses 3 wires. The manufacturer part number is IFS251, and it is designed for reliable metal detection in industrial environments.

Where to buy the IFM IFS251 sensor worldwide?

You can source the IFM IFS251 sensor through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time; we provide competitive sourcing for IFM components.

How to install the IFM IFS251 proximity sensor?

To install the IFM IFS251, mount the sensor securely in a non-ferrous holder to avoid interference. Connect the 4-pin M12 connector to a compatible cable, ensuring correct wiring for the NC output. Set the sensing distance per IFM guidelines, and verify operation with a metal target before use.
