SICK WFM Fork Sensor – Plug & Play Fork Sensor for Instant Installation

Key Highlights:

• Fixed parameters ensure a high level of operational safety with extremely simple commissioning.
• Clearly visible red light for easy alignment of the WFM.
• All-round visible receive indicator for continuous process monitoring.
• Multiple fork widths for easy installation in a wide range of applications.
• Robust aluminum housing suitable for harsh industrial environments.

Overview of SICK WFM Fork Sensor

The SICK WFM fork sensor is a plug-and-play fork sensor in which the emitter and receiver are integrated into a single rugged die-cast aluminum housing. The biggest advantage of the WFM is that no configuration or setup is required — the sensor is ready for immediate operation as soon as power is supplied, significantly reducing commissioning time.

A standout feature of the WFM is its yellow receive indicator, which is visible from all directions around the sensor. This allows technicians to monitor the operating status and troubleshoot from a distance without needing to approach the device directly. The robust die-cast aluminum housing combined with IP67 protection ensures reliable performance even in harsh industrial environments.

5 Key Features

• Plug & Play: Ready for operation immediately — no configuration or alignment required.
• All-round visible receive indicator (yellow receive indicator visible from every direction).
• IP67 Protection: Robust aluminum housing designed for industrial use.
• 5 Fork Widths: 30 mm / 50 mm / 80 mm / 120 mm / 180 mm.
• Switching Frequency: 4 kHz, response time ≤ 125 µs.

Industrial Applications of SICK WFM Fork Sensor

The SICK WFM fork sensor is an optimal plug-and-play solution that delivers reliable performance and effortless integration into industrial automation systems. Featuring a robust aluminum housing with IP67 rating, the sensor withstands harsh production environments. Combined with clearly visible red light and an all-round receive indicator, it enables convenient remote monitoring of operating status.

Main Applications:

• Object detection on production lines: The WFM rapidly and accurately detects the presence or absence of parts and components on conveyor belts and automated assembly lines. Thanks to its plug-and-play design, the sensor becomes operational immediately after connection, significantly reducing integration time and machine downtime.
• Presence monitoring of various objects: With fork widths ranging from 30 mm to 180 mm and fork depths up to 124 mm, the WFM is suitable for inspecting a wide variety of products such as bottles, cartons, metal sheets, electronic components, packaging, and many other objects. The sensor offers high resolution with a small Minimum Detectable Object (MDO), ensuring reliable detection even for thin or complex-shaped items.
• Shuttle positioning in intralogistics systems: The WFM36 model is a specialized double-fork solution for positioning shuttles in automated storage racks. SICK offers custom housing dimensions according to specific system requirements, along with a dedicated MOLEX cable, providing high accuracy and stability in high-speed warehouse environments.
• Inventory control and goods sorting: The all-round visible receive indicator allows technicians and control systems to monitor detection status from a distance, optimizing warehouse management, automated sorting, and inventory processes.

Comparison between WFM and WFE Fork Sensors – Which One to Choose?

*Note:

Choose the WFM if your application requires fast installation with absolutely no configuration. Choose the WFE if you need to adjust sensitivity according to environmental conditions or prefer push-pull PNP/NPN output in a single model.

Frequently Asked Questions about SICK WFM Fork Sensor (FAQs)

Q1: How much does the WFM fork sensor cost?

The price of the SICK WFM fork sensor depends on fork width, output type, switching mode, and connection style. Each model has a different price depending on specific application requirements.

Please contact AUMI directly for the best and fastest quotation along with expert advice on model selection.

Q2: Where can I buy genuine SICK WFM fork sensors?

AUMI is the official authorized distributor of SICK in Vietnam. When purchasing from AUMI, customers are guaranteed 100% genuine products, full CO/CQ certificates, official SICK warranty, and comprehensive technical support throughout the product lifecycle.

Q3: In which industries is the WFM fork sensor used?

The WFM is a versatile solution suitable for many industrial sectors, especially:

• Automated manufacturing: detection of components on assembly lines, conveyors, and packaging machines.
• Intralogistics & automated warehouses: shuttle positioning and rack control.
• Quality control & sorting: presence detection, inventory monitoring, and automated goods classification.
• Other industries: food & beverage, pharmaceuticals, electronics, mechanical engineering, automotive, etc.

With the ability to detect thin objects (MDO as small as 0.8 mm) and wide fork openings, the WFM flexibly meets most object detection needs in industrial environments.

Q4: Does the WFM fork sensor require alignment or configuration during installation?

No configuration is required at all. The WFM is a true Plug & Play sensor from SICK. All parameters are pre-configured at the factory. Users simply mount the sensor in the desired position, supply power, and it is ready to operate immediately.

This design saves significant installation and startup time, minimizes errors from incorrect settings, and enhances long-term operational reliability.

Q5: What is the difference between WFM36 and standard WFM models?

The WFM36 is a specialized Double Fork version developed by SICK specifically for shuttle positioning in automated warehouse systems (Intralogistics).

Unlike standard single-fork WFM models, the WFM36 uses a dedicated 4-pin MOLEX cable and supports custom housing dimensions according to each rack system’s requirements. This delivers superior accuracy, stability, and easy integration into high-speed modern shuttle systems.
