This document describes the P1KHxxx series of reflex sensors with background suppression, featuring high-end performance and teach-in functionality, manufactured by wenglor sensoric elektronische Geräte GmbH.

Function Description

The P1KHxxx reflex sensors operate on the principle of angular measurement, analyzing light reflected from objects. This design minimizes the influence of an object's color, shape, and surface characteristics on the detection range, allowing for reliable detection of even dark objects against a bright background. The sensor switches its output when an object enters the selected range. These sensors are designed for a wide array of industrial applications, including special machinery manufacturing, heavy machinery manufacturing, logistics, automotive, food, packaging, pharmaceuticals, plastics, woodworking, consumer goods, paper, electronics, glass, steel, aviation, chemicals, alternative energy, and raw materials extraction.

The sensors are not safety components according to 2006/42/EC (Machinery Directive) and are not suitable for use in potentially explosive atmospheres. They should only be used with wenglor-supplied or approved accessories and products.

Usage Features

Installation:

The sensor must be protected from contamination and mechanical influences during installation.
All applicable electrical and mechanical regulations, standards, and safety rules must be observed.
The sensor should be mounted securely, adhering to specified torque values (e.g., M3 screws at 0.5 Nm).

Control Panel:

The sensor features a control panel with:
- Switching distance adjuster A1 (5a)
- Switching distance adjuster A2 (6a)
- Teach Button (06)
- Supply power indicator (68)

Teach-in Mode: The switching distance can be taught in for both outputs using the teach-in key on the sensor.

Teach-In for Switching Output 1 (Foreground Teach-In by default):
1. Mount the sensor.
2. Press and hold the teach-in key until LED A1 blinks.
3. Release after 2 seconds.
4. LED A1 lights up to confirm successful teach-in.
Teach-In for Switching Output 2:
1. Mount the sensor.
2. Press and hold the teach-in key until LED A2 blinks.
3. Release after 5 seconds.
4. LED A2 lights up to confirm successful teach-in.
Foreground Teach-In: The sensor focuses on the object, and the switching distance is set slightly greater than the clearance between the sensor and the object. This activates the sensor for objects at or closer than the taught distance.
Background Teach-In: The sensor spot is aligned to the background, and the switching distance is set slightly less than the clearance to the background. This activates the sensor when an object is located between the background and the sensor.

Pin Function, I/O2 (Configurable):

Input External Teach-In:
- Set E/A2 pin function to external teach-in.
- With Ub setting active: Apply 18-30 V to E/A2 for 1-4 seconds. A1 is taught in when voltage drops.
- With Ub setting inactive: Disconnect I/O2 or connect to 0 V for 1-4 seconds. O1 is taught in when voltage is applied.
Locking: Continuous activation of the teach-in input locks the teach-in key, protecting against inadvertent changes.
Error Output: The error output switches in cases of contamination, aged emitter diode, unreliable working range, short-circuit, over-temperature, or hardware error.

Settings via IO-Link: Further functions and settings can be configured via the IO-Link interface, including:

PNP/NPN/push-pull
NC/NO
Switching hysteresis
On/off-delay
Operating mode
Switch emitted light off
Test mode
Data storage
Process and parameter data, as well as the IODD, are available on the wenglor website.

Diagnostics (Contamination Warning - blinking LED):

Continuous blinking at approx. 2.5 Hz:
- Contamination: Clean the optic cover.
- Aged emitter diode: Replace the sensor.
- Unreliable working range: Increase switching distance or reduce distance between sensor and object.
- Short-circuit: Check electrical wiring and eliminate the short-circuit.
Continuous blinking at approx. 5 Hz:
- Over-temperature: Disconnect power, allow to cool.
- Hardware error: Replace the sensor.

Maintenance Features

The wenglor sensor is maintenance-free.
Regular cleaning and inspection of plug connections are advisable.
Do not clean the sensor with solvents or cleansers that could damage the product.
