SICK WTB26P-24161120A00 Proximity Sensor

Name: SICK WTB26P-24161120A00 Proximity Sensor | Seven Star LLC
Brand: SICK
SKU: WTB26P-24161120A00

Description

SICK lists the WTB26P-24161120A00 as a W26 photoelectric proximity sensor with background suppression under part number 1218666. It is chosen where a plain diffuse sensor would mistake the machine behind the product for the product itself. The data sheet gives a maximum sensing range of 1,600 mm. The switching output is Push-pull: PNP/NPN with light/dark switching, the supply is 10 V DC … 30 V DC and the connection is Male connector M12, 4-pin.

Background suppression on the W26 housing

Because the decision is geometric rather than energy-based, target colour and gloss matter far less than with a plain diffuse proximity sensor, although very shiny or strongly angled surfaces still deserve a trial on the real part. Set the cut-off distance with the real product and the real background in place rather than on a bench; the setting is only as good as the conditions it was made under.

Its emitter is a PinPoint LED emitting visible red light with a spot of Ø 7 mm (700 mm). It is adjusted through bluePilot; For setting the sensing range. It responds in SIO Logic: 600 µs ; IOL: 750 µs at SIO Logic: 800 Hz ; IOL: 650 Hz switching frequency. The device also offers IO-Link (✔ , IO-Link V1.1), so the switching point and Smart Task logic can be set over the link instead of at the adjuster.

Type code WTB26P-24161120A00 and part number 1218666

WTB26P-24161120A00 identifies a version within the WTB26P family, and 1218666 is its number in SICK’s system. Where an S-suffix or a changed digit appears in a similar code, treat it as a different product until the data sheet says otherwise.

Versions SICK lists next to this one, all with separate part numbers:

WTB26P-24162120A00 (part no. 1221002)
WTS26P-24161120A00 (part no. 1218668) – Functional principle detail: Background suppression
WTB26P-24161420A00 (part no. 1222709)
WTB26P-24161520A00 (part no. 1222705) – Functional principle detail: Background suppression

Mounting, wiring and set-up notes for WTB26P-24161120A00

Plan for 10 V DC … 30 V DC at the terminals, IP66 (EN 60529); IP67 (EN 60529); IP69 (EN 60529) enclosure protection and an operating ambient of –40 °C … +60 °C. Current draw is ≤ 30 mA, without load. At UB = 24 V. The body measures 24.6 mm x 82.5 mm x 53.3 mm and weighs Approx. 80 g. Make sure the controller input matches the output type; a PNP sensor cannot simply replace an NPN one without changing the input wiring.

About brand

Machine builders have relied on SICK since 1946 for the sensors that tell a controller where a part, a pallet or a person is. The company, based in Waldkirch, Germany, makes photoelectric, inductive and magnetic sensors, distance sensors and safety devices. Seven Star LLC supplies SICK sensors to maintenance teams and integrators in Oman, mostly as exact replacements identified by type code and part number.

SICK sensor families on this page

Five of the SICK families listed here are described below. The W4 miniature photoelectric sensors include the WTB4-3, a proximity sensor with background suppression. IME is the standard inductive proximity line, and the IME18 is the M18 housing size. RZT7 cylinder sensors fit T-slot pneumatic cylinders and detect the piston magnet. The DT35 belongs to the Dx35 laser distance sensors for mid-range measurement. The microScan3 is a safety laser scanner that guards hazardous zones around machines and vehicles.

Where SICK sensors are used

SICK sensors are fitted on packaging and bottling lines, conveyors, palletizers, warehouse cranes and automated guided vehicles. Safety laser scanners protect robot cells and transfer cars. In process plants, the same proximity and cylinder sensors report valve and damper positions on packaged equipment.

Ordering SICK sensors: what we need

A SICK type code such as IME18-08NPSZW2K packs the whole specification into one string: housing size, sensing range, flush or non-flush mounting, output type and connection. Each variant also has a 7-digit part number, and that number is the safest identifier. Please send:

Type code and part number from the sensor label, or a photo of it
Output type (PNP or NPN, normally open or closed) and connection (cable length or M8/M12 plug)
For microScan3: variant (Core or Pro), interface, protective field range, plus system plug and bracket

We check the code in SICK's documentation and tell you if the manufacturer lists a successor.
