Inductive Cylindrical sensors PFM Series

Datasensing PFM Series

The PFM Series delivers reliable and durable inductive sensing optimized for tough, wash-down and food-grade installations. With a corrosion-resistant stainless-steel (AISI 316L) housing, high ingress protection levels (IP67 – IP68 – IP69K) and multiple sensing-distance variants, these sensors ensure consistent metal-object detection even in hygienic or wet environments. 

Design & Functionality

• The housing is made from AISI 316L stainless steel (DIN 1.4404), ensuring outstanding resistance to cleaning chemicals and mechanical wear — ideal for food & beverage and pharmaceutical production lines. 
• Equipped with a yellow LED status indicator, providing visual diagnostics and aiding rapid maintenance checks. 
• Rated for IP67 / IP68 / IP69K protection, the PFM Series stands up to high-pressure wash-down, steam cleaning and harsh environments where standard sensors may fail. 
• Available in standard and long-distance models, for flexible detection distances depending on mounting clearance and target size. 
• Built-in electronics include reverse-polarity protection, short-circuit auto-reset, impulsive over-voltage protection and ripple immunity ≤ 10% — delivering industrial-grade reliability even in dirty or unstable power conditions. 

Total Crossed Beams

(In this inductive sensor context, this means a stable detection field across the sensor face rather than literal optical beams.)

• The PFM Series ensures a uniform sensing zone even under challenging conditions such as fluid spray, metal mounting plates or irregular target surfaces — enabling repeatable detection of metal parts in food-grade automation setups.
• As a result, installations achieve fewer missed detections or false triggers even when the mechanical setup or environment is less controlled.

Beam Pitch Options

(Here this refers to selectable nominal sensing distances and mounting types rather than literal beam pitch.)

• The sensor lineup includes variants such as nominal sensing distances of ~2 mm (flush mount) and ~4 mm (non-flush) in M12 format. 
• Correction factors for various metals are provided (e.g., copper ~0.33, aluminium ~0.40, brass ~0.50, stainless steel ~0.80) enabling designers to calibrate for specific target materials. 
• High switching frequency (for example 2 kHz in many models) supports high-speed detection of metal parts on fast conveyors or packaging lines. 

Intrinsic Synchronism

• The PFM Series incorporates fully integrated electronics for timing, protection and output stability — no external synchronisation wiring is required, simplifying installation.
• Time-before-availability is ≤ 50 ms in many models, ensuring the sensor is ready quickly after power-up—an important factor for packaging line uptime. 

Operational Advantages

• Hygienic & Durable Design: With a stainless-steel body, IP69K rating and LED diagnostics, the PFM Series is built for environments requiring frequent cleaning, high hygiene and durability under wash-down.
• Flexible Sensing Distance Options: The availability of both standard and long-distance variants allows adaptation to both tight-clearance mounting and larger target sizes — ideal for packaging, food handling and general manufacturing.
• Reliable Metal Detection: With high repeatability (<5%), metal correction factors, and robust electronics, these sensors deliver dependable detection across a range of metal materials and in wet or industrial environments.
• Applications: Perfect for conveyor and packaging systems in food & beverage, pharmaceutical, chemical and general manufacturing lines — especially where metal-part detection, wash-down resistance, and industrial robustness are required.
