Product description
For mounting, the SICK WTB27-3P2411 provides a rectangular sensor housing measuring 24.6 × 80.6 × 54 mm. Two through mounting holes with a diameter of 5.2 mm are located in the rear housing area; the optical output is on the narrow end face. The housing is made of ABS and the optics of PMMA. With a device weight of 100 g, this version has an IP69K enclosure rating and is specified for an operating environment of −40 to +60 °C. Status indicators for supply and reception, as well as the front-mounted potentiometer, complete the mechanical design. A temperature range of −40 to +75 °C applies to storage. The electrical protection class is III; the specification cites EN 60947-5-2 for electromagnetic properties. As an optoelectronic photoelectric proximity sensor in the W27 product family, this version operates with background suppression. The specified sensing range is 100 to 1,600 mm; the data sheet states a maximum range of 30 to 1,600 mm. The infrared LED emits at 880 nm and produces a light spot approximately 25 mm in diameter at a distance of 800 mm. This provides a variant-specific account of the detection principle and optical characteristics. Electrically, the WTB27-3P2411 is supplied with 10 to 30 V DC. The four-pin M12 connector provides the connections for the supply and switching signal. The PNP output has a complementary design and supports light and dark switching. An output current of up to 100 mA, a response time of no more than 1.5 ms, and a switching frequency of 350 Hz describe its switching behavior. For verification, the complete type designation, SICK part number 1025994, output type, pin assignment, sensing range, and housing dimensions are relevant.

What electrical output configuration does the WTB27-3P2411 have?
This version operates with a complementary PNP switching output for light and dark switching, a 10 to 30 V DC supply, and a four-pin M12 connector.
What applies if an item develops a defect within 14 days?
For the condition categories “Used, removed from an installation” and “New, old stock”, the contractual 14-day right of return in the event of a defect applies. The defect must occur within 14 calendar days after delivery and be reported in text form within the same period.
In particular, the REHA tamper-evident seal must remain fully intact and our RMA approval is required before return. In an accepted case, we decide between replacement and refund. Details in Section 11 of the Terms.
Which shipping methods and delivery times are available?
The shipping method, shipping cost and estimated delivery time are confirmed for the specific order. Depending on the item, destination and urgency, we can check parcel, express or freight shipping as well as collection.
A delivery date is binding only if we expressly confirm it as binding.
Which payment terms apply?
The payment terms stated in the checkout or order confirmation apply. Depending on the order and customer, payment is made in advance or against invoice.
International deliveries and deliveries to new customers are generally made against advance payment unless we expressly confirm another payment arrangement.
Can I return an item ordered incorrectly or found incompatible?
No. There is no general B2B right of return, exchange, cancellation or withdrawal. Incorrect or duplicate orders and a lack of suitability or compatibility with the customer’s installation are not covered by the contractual 14-day right of return in the event of a defect. Details in Section 12 of the Terms.
Can I request individual pricing for several items?
You may request an individual quotation for several items or larger quantities. We then check availability and pricing for the specific requirement; there is no entitlement to a quantity discount. Open the quick enquiry.
Do you also purchase industrial spare parts?
Yes. You can offer us automation and drive components for purchase. Please provide complete type numbers, quantities, condition details and photographs where possible.
After review, we will tell you whether a purchase is possible and on which terms. Learn more about selling industrial stock.
