•Detection of water-based fluids inside a container or tube without direct contact with the fluids.

•The sensor detects the liquids reliably while compensating for residue film, moisture, or foam build-up from liquids such as water, milk, bodily fluids (blood), acid, or alkaline solutions with conductivity as high as

50 mS/cm inside or outside the container wall.

•Flexible and fast universal mounting bracket.

•The sensing principle detects only the level of the liquids while ignoring foam, film, or build-up that would cause standard capacitive sensors to detect faultily.

Features

•Compact housing

•Supply voltage: 10…30V DC

•Output: 100 mA, NPN or PNP preset

•Make or break switching function

•Status indication for output and power ON

•Protection: reverse polarity, short circuit, and transients

•Cable and pigtail M8 plug versions

•Excellent EMC performance

•IP65, IP66, IP67, IP68, and IP69K for hose-down applications

Chapter 1 Product Overview

IO-Link Sensors	875L DC Cylindrical Cap
	• The sensor can be operated in IO-Link mode once it is connected to an
	IO-Link master or in standard I/O mode.
	• Adjustable parameters via IO-Link interface: Sensing distance and
	hysteresis.
	- Sensing modes: single-point, two-point, or window mode.
	- Timer functions like: on-delay, off-delay, one shot leading edge, or
	trailing edge.
	- Logic functions such as: AND, OR, XOR, and SR-FF.
	- External input.
	- Logging functions: Maximum temperatures, minimum temperatures,
	operating hours, operating cycles, power cycles, minutes above
	maximum temperature, minutes below minimum temperature, and
	so on.

Features

•A complete family. Availability in M18 in a robust PBT housing with an operation of 2…10 mm (0.08…0.39 in.) flush or 3…15 mm (0.12…0.59 in.) non-flush.

•The output can be operated either as a switching output or in IO-Link mode.

•Fully configurable via output IO-Link v 1.1. Electrical outputs can be configured as PNP/NPN/Push-pull/External input, normally open or normally closed.

•Timer functions can be set, such as on-delay, off-delay, and one shots.

•Logging functions: temperatures, detection counter, power cycles, and operating hours.

•Detection modes: single-point, two-point, and window mode.

•Analog output: In IO-Link mode, the sensor generates 16-bit analog process data output that represents the dielectric value that the sensor measures.
