Photoelectric Cubic sensors TFM Series

Datasensing TFM Series

The TFM Series offers a sophisticated family of miniaturised time-of-flight sensors, engineered for precise distance measurement, space-constrained installation, and robust industrial performance. With model versions supporting nominal sensing distances from ~180 mm up to ~600 mm (depending on variant) and a resolution as fine as 1 mm, the series provides exceptional measurement precision, flexible output configuration, and rugged construction. 

Design & Functionality

• The TFM sensors are built in an extremely compact housing (approx. 13 × 31.2 mm for many models) and are completely resin-filled, delivering excellent protection against moisture and contaminants. 
• Optical measurement is based on Time-of-Flight (ToF) principle with an infrared Class 1 laser emitter, giving both distance and presence detection capability.
• Nominal sensing distances:
  • ~180 mm (low range version) with ~1 mm resolution. 
  • ~600 mm (high-range version) with ~3 mm resolution. 
• Switching frequency options: Up to ~80 Hz in certain versions. 
• Output logic: Dual digital outputs, selectable PNP or push-pull, and configurable switching logic. 
• Electrical & mechanical specifications: Operating voltage ~19.2-28.8 V DC; resin-filled housing; protection rating IP67. 

Total Crossed Beams

(In this context, this means the sensor maintains consistent detection coverage across its measurement zone rather than literal crossed beams.)

• The TFM Series ensures a stable measurement/detection field, even when targets vary in position, surface reflectivity or size — resulting in fewer missed detections, higher repeatability and better reliability in automation systems.
• Its miniature footprint combined with ToF measurement makes it highly suitable for robotics, packaging, conveyor modules and compact automation zones where precision and space-efficiency are required.

Beam Pitch Options

(Here interpreted as selectable distance capability / variant options rather than literal beam spacing.)

• Low-range variant: ~180 mm nominal range, ~1 mm resolution. 
• High-range variant: ~600 mm nominal range, ~3 mm resolution. 
• These options allow you to pick a TFM model that matches your target distance, mounting clearance and detection requirements — offering design flexibility and application suitability.

Intrinsic Synchronism

• The ToF electronics and optics are integrated within the compact sensor housing — no external synchronising modules are required — simplifying wiring, reducing commissioning time, and improving installation cleanliness.
• With built-in diagnostic LEDs (run, out-of-range, status) and a fully sealed resin-filled body, the TFM Series supports robust performance in challenging machine-side or packaging line conditions.

Operational Advantages

• Precision in compact form: The TFM Series provides high-resolution distance measurement and presence detection in a very small footprint — ideal for automation spaces where mounting room is limited but performance must be high.
• Versatile installation and output: With selectable logic (PNP/push-pull), dual outputs, and small housing, the sensor integrates into a variety of control systems and machine layouts.
• Rugged industrial design: IP67 protection, resin-filled housing, small size and laser emission make the series durable and suited for machine environments with dust, splash or tight clearances.
• Applications: Ideal for object presence/distance detection in packaging machinery, pick-and-place robots, conveyor modules, compact assembly equipment, and any scenario requiring precision detection, limited installation space, and reliable performance.
