What type of sensor is this?

This is an inductive proximity sensor designed to detect metal objects without physical contact. It belongs to the SICK IME range and has the model designation IME18-08NPSZC0S.

What is the nominal sensing range?

The nominal sensing range is 8 mm. The specified safe sensing range is 6.48 mm, although the effective distance can vary with the target material and installation conditions.

Which materials can it detect?

It detects metallic targets. Its rated sensing distance is based on steel, while stainless steel, aluminium, copper and brass typically produce shorter operating distances.

What type of output does the sensor provide?

It provides a PNP, normally open output using a three-wire DC configuration. The output activates when a suitable metal target enters the sensing area.

What supply voltage is required?

The sensor operates from a 10–30 V DC supply and has a maximum no-load current of 10 mA.

How much current can the output handle?

The switching output is rated for a continuous current of up to 200 mA. The connected load should remain within this limit.

What electrical connection does it use?

The unit has a male, four-pin M12 connector. Pin 1 is the positive supply, pin 3 is the negative supply and pin 4 is the normally open switching output; pin 2 is not connected.

Is this a flush-mounting sensor?

No. It is designed for non-flush installation, so adequate clearance around the sensing face is required to minimise interference from nearby metal.

What are the sensor's dimensions?

The cylindrical housing has an M18 x 1 thread, an 18 mm diameter and an overall length of 69 mm. The threaded section is 42 mm long.

What is the switching frequency?

The switching frequency is 1,000 Hz, allowing the sensor to detect rapidly moving metal targets in counting, positioning and machine automation applications.

What environmental protection rating does it have?

SICK 1040950 has an IP67 enclosure rating, indicating protection against dust ingress and temporary immersion under the conditions defined by EN 60529.

What operating temperature range is specified?

The specified ambient operating temperature range is -25°C to +75°C.

What materials are used in its construction?

The housing is made from nickel-plated brass, while the sensing face is made from PA 66 plastic. Two nickel-plated brass mounting nuts are supplied.

Does it include electrical protection features?

Yes. The design includes short-circuit protection, reverse-polarity protection and power-up pulse protection.

What is the maximum permitted tightening torque?

The maximum specified tightening torque is 40 Nm. Installation should use the supplied mounting nuts and avoid exceeding this value.

What accessories are compatible with the sensor?

Compatible options include M18 mounting plates, mounting brackets, clamping blocks and A-coded four-pin M12 female connectors or sensor cables. The accessory selected should suit the installation layout and required cable length.
