Frequently asked questions
How do I get current pricing and availability for WTB2S-2P3160?
Submit an RFQ with your target quantity and delivery window; pricing and stock levels are confirmed at quote time through independent distribution.
Will WTB2S-2P3160 drop into a panel that was specified around WTB2S-2P3110 without rewiring?
The WTB2S-2P3110 uses a cable with M8 connector (200 mm pigtail) and has a shorter 18 mm sensing range, while the WTB2S-2P3160 has a direct M8 3-pin connector and 66 mm range. The mounting footprint is identical (7.7 mm wide, 21.8 mm tall, 13.5 mm deep), but the termination differs — you would need to adapt the cable or use a mating M8 cordset. Both are PNP Light-ON, so the electrical wiring is the same.
What is WTB2S-2P3160's listed width?
The width is 7.7 mm, height 21.8 mm, and depth 13.5 mm.
The SICK WTB2S-2P3160 is a photoelectric proximity sensor from the W2S-2 family, using background suppression to detect objects within a 1 mm to 66 mm range regardless of color or reflectivity. It switches on light reception (Light-ON) and outputs a PNP signal at up to 50 mA, with a response time of 500 µs. The visible red pinpoint LED makes alignment straightforward during commissioning — you see the spot on the target.
The 66 mm sensing distance with background suppression means this sensor ignores background objects beyond that point — useful on conveyors where product passes in front of a fixed backstop. The 500 µs response keeps up with fast-moving parts on a pick-and-place or packaging line. IP67 rating lets it handle washdown splashes and dust in food or light industrial environments. The M8 3-pin connector (not a pigtail) keeps the footprint tight: 7.7 mm wide, 21.8 mm tall, 13.5 mm deep — fits between machine frames or in a tight rail section. Operating range is 10–30 VDC, with the PNP output sourcing up to 50 mA. Temperature span from -25 °C to +50 °C covers most indoor factory conditions but not freezer or oven zones.
