ifm O6H700 Diffuse Sensor with Background Suppression, 100 mm

ifm O6H700 Diffuse Sensor with Background Suppression, 100 mm

The ifm O6H700 is a very compact diffuse reflection sensor with background suppression, 35.4 x 13 x 21 mm in size. It detects objects between 1 and 100 mm using a red light beam (650 nm, laser protection class 1) and a small light spot of up to 2 mm in diameter, which makes it suitable for small parts and precision feeding. The range can be adjusted, and on grey and black objects it still detects from 8 and 12 mm.

The O6H700 is supplied with a 2 m PUR cable (3 x 0.25 mm2) and has an IO-Link interface with a PNP output, light-on or dark-on selectable. Seven Star LLC supplies the O6H700 in Oman and the GCC as an independent supplier.

O6H700 technical specifications

The table lists the values published by the manufacturer for the O6H700. Where a parameter has several operating modes, the headline value is shown; the full parameter list is in the manufacturer documentation.

How the O6H700 works

The O6H700 is a diffuse reflection sensor with background suppression: it emits a red light beam and evaluates the light returned from the target, using the geometry or the time of flight of the signal to decide whether the object is inside the set distance. Anything beyond that set distance, such as machine parts or a conveyor, is ignored regardless of how bright it is. This makes the sensor tolerant to differences in colour and surface, and the switching point can be adapted to the application.

Where the O6H700 fits and related parts

In this group the O6H700 is the smallest and has the shortest range. The OGH580 offers 15 to 200 mm in a metal housing with an M18 thread on the side, and the O5D100 reaches 2 m. Pick the O6H700 when the available space is very restricted and the objects are small.

Selection and ordering checklist for the O6H700

Work through the points below before you confirm the order, so that the O6H700 you receive is the one your machine or plant needs.

• Confirm the detection distance 1 to 100 mm and the part’s colour
• Note switching frequency up to 1000 Hz for fast pass rates
• Choose the 2 m cable version, since there is no plug on this article
• Decide on light-on or dark-on
• Confirm mounting through the screw holes (tightening torque 0.5 Nm)

The manufacturer lists this article under the type designation Diffuse reflection sensor with background suppression, O6HLFPKG. The article number O6H700 is the reference to quote when ordering, and the type designation is useful for technicians who compare the label on an installed unit.

Installation, commissioning and maintenance

Mount the sensor on a rigid bracket so that the beam meets the target at the intended angle, and keep the lens clean. Align the housing so the light spot lands on the object rather than on edges, and avoid placing a shiny background directly behind the sensing range. At commissioning, set the switching distance using the operating method of the device (pushbuttons or IO-Link), test with the darkest and brightest product you handle, and verify switching at the extremes of the part positions. Clean the lens in dusty areas and re-check the setting when the bracket or the product changes.

The screws should be tightened to 0.5 Nm only, because the housing is plastic. Adjust the range with the sensor aligned on the actual product and test the background in its worst-case position. With a 2 mm spot, alignment is critical for small parts, so fix the bracket firmly.

Typical applications in Oman and the GCC

Small parts detection in assembly, feed monitoring in packaging, edge and presence detection on short conveyors. In Oman and the GCC it fits small machines and lab or production equipment where the compact size matters.

Optical sensors on open conveyors and loading areas meet dust, sand and strong sunlight. Regular lens cleaning, a firm bracket and a check of the switching point after any mechanical change keep detection reliable.
