• IO-Link appears across the photoelectric range, with remote setting and diagnostics.
• Choose SICK for one-vendor coverage.
• Do not choose it on price alone, because the quote changes with connector, cable length and output type.

Banner Engineering is a strong match for packaging, material handling and food and beverage lines. The QS18 series lists an opposed range of 20 m, a non-polarised retroreflective range of 6.5 m, a polarised retroreflective range of 3.5 m, a diffuse range of 600 mm, a fixed-field range of 200 mm and an adjustable-field range of 350 mm. Its response time is listed as 600 to 800 microseconds, and IO-Link and clear object detection are listed as available on QS18 models.

• The T18-2 series adds IP69K protection and an FDA-grade shatterproof plastic housing with ECOLAB certification for washdown and thermal shock.
• The Q2X adjustable-field model offers a cutoff distance between 18 mm and 150 mm for dark wafers.
• Choose Banner for washdown housings and clear object detection.
• Check the emitter type first, because LED and laser versions have different ranges.

ifm electronic, written as ifm, is a good match for buyers who want IO-Link data as well as a switching signal. Its measuring photoelectric sensors provide the distance value to the nearest millimetre through IO-Link, and switch points can be set through software. The IO-Link device pages list inductive, capacitive, magnetic and ultrasonic position sensors, with switch point teach, switching cycle counters, operating hours counters and device status available through IO-Link.

• The process sensor range covers pressure, temperature, flow and level for liquids, air and gases.
• The moneo configure tool is available at no charge for setting IO-Link sensors and masters, and ifm states that it can set devices from other makers a
• Choose ifm when IO-Link diagnostics and process sensing sit on the same project.
• Do not choose it on the free setup tool alone, because the sensor, the IO-Link master and the cables are still quoted separately.

Balluff is a close match for IO-Link photoelectric and inductive sensing, with a focus on diagnostics and one housing style across many models. The BOS 6K family uses one uniform housing design, one user interface and IO-Link across red light, blue light and laser models. The intelligent PNP and NPN output reduces the variants a buyer needs to stock, because one model can serve both output types.

• The BOS 21M ADCAP multi-function sensor offers four sensor modes through IO-Link, and it monitors light intensity and LED brightness so a dirty lens s
• Balluff states that one hub can connect up to 16 binary standard sensors, which cuts wiring on a conveyor or a packaging machine.
• The Balluff Engineering Tool gives vendor-independent setup and diagnostics for IO-Link devices, but a licence is needed for each device where the too
• Choose Balluff for IO-Link diagnostics and a hub that groups many binary sensors.

Turck is the strongest match in this list for buyers who need Pepperl+Fuchs style interface and hazardous-area work as well as sensors. Its interface range covers galvanic isolation, signal conversion and signal conditioning for Ex and non-Ex applications, and its safety range covers safety light curtains, emergency stop controls, relays and safe I/O modules. The BI15U-EM30WD-IOL6X2-H1141 inductive sensor lists factor 1 for all metals, resistance to magnetic fields, a temperature range from minus 40 degrees C to plus 100 degrees C, IP68 and IP69K protection and a special double-lip seal.

• The LRS510 radar family covers level from 0.35 m to 10 m with IP67 and IP69K protection, and it offers signal strength, temperature, operating hours a
• Choose Turck when the job mixes sensors, IO-Link masters and hazardous-area interfaces.
• Confirm the Ex approval and the zone for the exact model first, because approvals change by variant.

Omron is a good match for compact photoelectric and proximity sensing on machines where space is tight and the sensor count is high. The E3Z compact photoelectric family covers all common sensing modes at long range, with a through-beam sensor distance of 10 m on the red LED model. The E3Z-IL series adds IO-Link so sensor level information is visible at the controller.

• The E2E Next inductive family offers up to 4 times the sensing range of standard models, with factor 1 sensing of ferrous and non-ferrous metals.
• Omron guidance lists up to 10 sensors with the E3C-LDA amplifier model and up to 2 sensors with E3T, E3Z, E3ZM and E3S-C models in some layouts.
• Choose Omron for compact sensors and clear mounting guidance.
• Check the interference limits for the exact model first, because a second sensor mounted too close can make the output unstable.

KEYENCE is the match for high-speed, laser and measurement sensing where a standard photoelectric sensor is not precise enough. The LR-X laser sensor detects targets by position and is unaffected by colour, surface finish or shape, with position changes as small as 0.5 mm and a stainless steel housing in food-grade SUS316L. The LR-T reflective series offers a detectable distance of up to 500 mm.

• The ER-N separate-amplifier proximity sensor responds in 150 microseconds, uses an OLED display for numeric setting, and allows up to 16 amplifiers in
• The EM small proximity heads have a sensor head diameter as small as 3 mm, which suits presses, grippers and small-part detection.
• Choose KEYENCE for laser position sensing, fast response or a very small head.
• Get a written quote and a lead time first, because the direct sales route can add days to a first order.
