IN121100 – IPF inductive sensor

IN121100 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 50 mm, rated sensing distance 6 mm, supply 10–30 V DC, NPN output with NO contact, connection: PVC cable 2 m, 3 wires.

Key features

• Sensing distance 6 mm – rated value according to the manufacturer's catalogue data.
• Output NPN / NO – electrical design of this variant.
• Supply 10–30 V DC – permissible supply voltage range.
• Non-flush mounting – design of the active face according to the manufacturer.
• Connection: PVC cable 2 m, 3 wires – 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 IN121100

Electrical connection IN121100

IN121100 uses the connection PVC cable 2 m, 3 wires. The manufacturer states the number of wires: 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 IN121100

The active face is designed for non-flush mounting. Free space must remain around the face according to the manufacturer's installation drawing, otherwise surrounding metal may affect the range.

Typical applications IN121100

• 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 6 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.
• Non-flush version: check that the installation method matches the manufacturer's installation drawing.
• Output NPN: must match the input type of the control system.
• NO contact: the output changes state when the target is detected.
• Connection: PVC cable 2 m, 3 wires: 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.
