SICK 1016102, model WL12-2P430, is a compact photoelectric retro-reflective sensor designed for dependable object detection in industrial automation applications. Housed in a robust zinc die-cast metal body with a rectangular form factor, it combines durable construction with a space-saving footprint of 15 mm x 49 mm x 41.5 mm, making it well suited to installation where mounting space is limited.
This sensor uses a visible red LED light source and offers a switching distance of up to 5 m, with a maximum range of 7 m when used with a suitable reflector such as the PL80A. Sensitivity is adjustable by potentiometer, allowing the device to be set to suit the application. The WL12-2P430 features a PNP switching output, light/dark switching capability, a fast response time of up to 330 µs, and operates from a 10 V DC to 30 V DC supply.
With an M12 4-pin connector, IP67 protection rating, PMMA optical elements, and an operating temperature range from -40 °C to +60 °C, this sensor is a practical choice for demanding environments where reliable optical detection and consistent switching performance are required.

What type of device is this?
This is a reflex photoelectric sensor used for object detection in industrial automation systems. It works with a separate reflector and is designed for reliable presence sensing in compact installation spaces.
How does this sensor detect an object?
The sensor emits visible red light towards a reflector. When an object interrupts the returned beam, the sensor changes its switching state. This makes it suitable for conveyor, packaging and general machine sensing duties.
What sensing range can I expect?
The standard switching distance is 0 m to 5 m, with a maximum switching distance of up to 7 m under stated conditions. The published maximum figure is based on use with a PL80A reflector.
What kind of light source does it use?
It uses a visible red LED light source. This can make alignment easier during installation compared with sensors that use non-visible light.
What output type does it have?
This version provides a PNP switching output and supports light-on/dark-on switching behaviour, making it adaptable to different control preferences in a machine circuit.
What supply voltage is required?
The sensor operates from 10 V DC to 30 V DC. The stated current consumption is 30 mA without load.
How is the unit connected?
It uses a 4-pin M12 connector, which is a common connection style in industrial sensor installations and helps simplify integration into existing machine wiring.
Can the sensing sensitivity be adjusted?
Yes. The unit includes a potentiometer for sensitivity adjustment, allowing the switching performance to be tuned to suit the application and reflector setup.
Is it suitable for demanding industrial environments?
The housing is made from die-cast zinc, the optical front is PMMA plastic, and the enclosure is rated IP67. These features make the 1016102 well suited to industrial environments where a robust sensor body is preferred.
What are the operating temperature limits?
The operating temperature range is -40 °C to +60 °C. The storage temperature range is -40 °C to +75 °C.
What are the physical dimensions?
The housing dimensions are 15 mm x 49 mm x 41.5 mm. Its rectangular format can be helpful where mounting space is limited.
How fast is the switching response?
The stated response time is up to 330 microseconds, which makes it suitable for applications requiring fast detection and switching performance.
Does the choice of reflector affect performance?
Yes. The achievable sensing distance depends on the reflector used. The published switching range values reference a PL80A reflector, and alternative reflector types can change the effective operating distance.
