Product details

Wide-Supply Inductive Sensing

It accepts a supply voltage of 24‑240 V AC or DC, making it usable across panels with mixed control voltages without stocking separate AC and DC variants. The shielded sensing face delivers a 5 mm sensing distance and the output is a 2‑wire normally open contact.

Environmental Rating

Rated IP67 and IP69K, with a nickel‑plated brass body that resists corrosion and high‑pressure washdown. The included indicator light provides local status at the sensor location.

Form Factor and Fit Considerations

The XS518B1MAU20 uses a 24 mm cylindrical body with a 1/2 in connector and is shielded for flush mounting. This form factor is distinct from flat‑block sensors such as the XS9D111A2M12, which has an 80×80×26 mm plastic housing and an M12 connector. Verify panel cutout diameter and connector type before substituting – they are not mechanically interchangeable and their sensing ranges differ (5 mm shielded vs 40 mm unshielded). No rewiring will make a flat block fit this bore.

Compliance

CE, CSA, and UL Listed, supporting global equipment certifiers and third‑party inspections.

Frequently asked questions

What series does the XS518B1MAU20 belong to?

It is part of the OsiSense XS5 series of cylindrical inductive sensors.

What key features does the XS518B1MAU20 offer?

Reverse polarity protection protects the electronics against miswiring, and an integral LED indicator lights when the output is active.

What compliance standards does the XS518B1MAU20 meet?

It is CE, CSA, and UL Listed, covering European, Canadian, and U.S. safety requirements.

Can the XS518B1MAU20 replace a sensor like the XS9D111A2M12?

No. The XS518B1MAU20 is a 24 mm cylindrical body with a 1/2 in connector; the XS9D111A2M12 is an 80×80 mm flat block with an M12 connector. They have different sensing distances and mechanical interfaces – a direct swap is not possible without rework.
