SICK WT260-R270 Photoelectric Proximity Sensor
The SICK WT260-R270 is a rectangular photoelectric proximity sensor designed for industrial detection tasks. It uses visible red LED light with an energetic detection principle to sense objects at distances between 5 mm and 1,300 mm, with a maximum range reaching 1,700 mm. The sensor weighs 120 g and carries an IP67 enclosure rating.
Check supply voltage and output compatibility
Verify that your system provides a supply voltage within 12 V DC to 240 V DC or 24 V AC to 240 V AC, as the unit draws up to 5 VA. The switching output is a relay with electrically isolated change-over contacts rated for 3 A at 240 V AC or 30 V DC, operating in light-switching mode. Ensure the 20 ms response time and 25 Hz switching frequency suit your control loop.
Mounting bracket included for rectangular housing
A BEF-W260 mounting bracket is supplied to secure the 25 mm x 78 mm x 63 mm plastic ABS housing with PC optics. The potentiometer offers 270° adjustment, while a selector switch sets on-delay or off-delay times between 0.1 s and 10 s. The cable gland connection and Protection Class II simplify wiring without needing an earth bond.

Questions about this item
Does the WT260-R270 ship with a mounting bracket, or do I need to order one separately?
The sensor is supplied with mounting bracket BEF-W260 in the box.
The sensing range is quoted as 5 mm to 1,700 mm maximum and 5 mm to 1,300 mm standard — which figure should I design for?
Design for the 1,300 mm sensing range; the 1,700 mm value is the absolute maximum under ideal conditions.
The relay output is rated at 3 A for both 240 V AC and 30 V DC — will it reliably switch a 240 V AC contactor coil in a cabinet?
Yes, the change-over relay is rated 3 A at 240 V AC and meets usage category AC-15 for inductive loads.
