Product details

What you're looking at

The SICK WT4-2P1321 is a photoelectric proximity sensor — the kind that sits on a bracket or DIN rail and fires a modulated light beam to detect objects without contact. Rated for 100 mA at 10–30 V DC, it's a standard low-power sensor for part-present, level, or edge-detection jobs on a conveyor or assembly fixture. The 100 mA output drives a PLC input or a small relay directly; the 10–30 V DC range means it works on common 24 V DC control supplies without a separate regulator.

Frequently asked questions

Where can I buy WT4-2P1321?

This part is sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm commitment.

Will WT4-2P1321 drop into a panel specified around WTR1-P721S09?

Both are photoelectric proximity sensors, but the WTR1-P721S09 has a 300–900 mm sensing range versus the WT4-2P1321's unspecified range, and it weighs 0.15 kg versus 0.01 kg. The mounting footprint and wiring may differ; verify the mechanical interface and detection distance before substituting.

What is WT4-2P1321's listed type?

It is a Photoelectric Proximity Sensor — a non-contact object detector using a modulated light beam.
