IB121221 – IPF inductive sensor

IB121221 IPF is an inductive sensor designed for non-contact detection of the position and presence of metal objects. This variant has: design M12, overall length 60 mm, rated sensing distance 3 mm, supply 10–30 V DC, NPN output with NC contact, connection: connector M12, 3 pins.

Key features

• Sensing distance 3 mm – rated value according to the manufacturer's catalogue data.
• Output NPN / NC – electrical design of this variant.
• Supply 10–30 V DC – permissible supply voltage range.
• Flush mounting – design of the active face according to the manufacturer.
• Connection: connector M12, 3 pins – electrical connection type of this variant.
• Degree of protection IP67 – degree of protection stated in the catalogue data.
• Ambient temperature -25–70 °C – permissible temperature range according to the manufacturer.

How an inductive sensor works

The active face of the sensor generates an electromagnetic field. When a metal object approaches it, the resulting eddy currents change the state of the oscillator and the electronics evaluate this change at the output. Detection takes place without mechanical contact between the sensor and the target.

Correction factors for different metals

The rated sensing distance applies to the manufacturer's reference target. For another material, the approximate range is determined as Sn × the correction factor given below. The values are taken from the catalogue data of this model.

Technical specifications IB121221

Electrical connection IB121221

IB121221 uses the connection connector M12, 3 pins. The manufacturer states the number of pins: 3. Before connecting, compare the actual wiring with the diagram in the manufacturer's datasheet; pin and wire colour assignments should not be derived from the connector type alone.

Mounting IB121221

The active face is designed for flush mounting. The sensor can be installed in a metal surrounding according to the manufacturer's installation drawing.

Typical applications IB121221

• detecting the presence of a metal part
• checking the end position of a metal part
• non-contact counting of metal objects

How to choose the right variant

• Sensing distance 3 mm: this is the rated catalogue value. When designing, take into account the material and size of the target as well as the mounting conditions.
• Flush version: check that the installation method matches the manufacturer's installation drawing.
• Output NPN: must match the input type of the control system.
• NC contact: the contact logic is normally closed.
• Connection: connector M12, 3 pins: the mating connector or cable must match the data in the datasheet.
• Degree of protection IP67: assess together with the specific environmental conditions and the connection method.
