FENAC FNC Series Speed Sensors: Precision and Motion Control

Accurate detection of speed and direction is an important requirement in motion control applications. The FENAC FNC series speed sensors comprise different models designed to detect the rotational speed and direction of metal gears with high resolution. The FNC SS16, FNC CSS18, and FNC SS20 series differ in their physical dimensions, target module options, and connection configurations.

Key Features of the FNC Series Speed Sensors

The main technical features of the FENAC speed sensor series are as follows:

• Detection: Rotational speed and direction of metal gears
• Target module options: 1, 1.5, 2, 2.5, 3, 4, and 30
• Frequency range: Wide frequency range
• Temperature range: Wide temperature range
• Output options: Speed and direction information; A, A′, B, and B′ signals
• Connection: Cable with an automotive connector

The models in this series offer different options in terms of physical dimensions. When selecting a model, the dimensions and connection characteristics of the relevant sensor should be taken into consideration.

FNC SS16 Series Speed Sensor

The FNC SS16 is a speed sensor model characterized by its cylindrical metal body and mounting flange. Its physical dimensions are as follows:

• Diameter: Ø16 mm
• Length: 60 mm
• Flange dimension: 42 mm
• Additional dimension: 21.7 mm

The FNC SS16 series provides speed and direction outputs. Its connection configuration consists of a cable with an automotive connector.

FNC CSS18 Series Speed Sensor

The FNC CSS18 is a speed sensor series featuring a cylindrical body and an attached cable. Its specified physical dimensions are as follows:

• Diameter: Ø18 mm
• Length: 54.5 mm

The FNC CSS18 series also features A, A′, B, and B′ outputs for speed and direction information. The connection type is a cable with an automotive connector.

FNC SS20 Series Speed Sensor

The FNC SS20 series features a connection cable and a flanged body design. The series includes two designs with different body dimensions.

FNC SS20 – First Design
