Product catalog summary
Specifications and Features
The KST94C-4N sensor is designed for automated vibration measurement, particularly in quality control. It features a movable tip guided by an air-damped piston/cylinder system, ensuring a linear frequency range through frictionless movement. The sensor guarantees reproducible results with constant tip pressure due to its spring suspension. It offers low distortion, minimal environmental vibration sensitivity, and a long life expectancy of over 10 million test cycles. The sensor is oil-resistant with an IP62 protection grade and provides an IEPE voltage output. The probe tip is electrically isolated from the body.

Technical Specifications
The sensor operates on a piezo shear design with an IEPE output. It has a voltage sensitivity of 100 ± 5% mV/g and a measuring range of ± 20 g at a force of 3 N. The frequency limits are 40 Hz (lower) and up to 3200 Hz (upper) depending on deflection and coupling. The resonant frequency is over 6 kHz, with a transverse sensitivity of less than 5%. The wideband residual noise is less than 0.6 mg, and noise density varies from 10 µg/√Hz at 10 Hz to 1 µg/√Hz at 100 Hz. The maximum stroke is 5.5 mm, with a recommended deflection of 2 to 4 mm and a maximum vibration displacement of 1 mm. The press-on force ranges from 2.2 N to 3.6 N, with a spring stiffness of 0.32 N/mm and a dynamic mass of 9 g.

Environmental and Mechanical Characteristics
The operating temperature range is 0 to 80 °C, with a temperature coefficient of -0.1%/K. The sensor weighs 120 g without cable and is made of stainless steel. It features a UNF 10-32 socket and can be mounted using a clamp collar or M5x8 screw.

Accessories
Available accessories include various IEPE cables and adapters, such as the 050 IEPE cable (2 x UNF 10-32, 1.5 m long) and the 017 adapter (UNF 10-32/BNC).

Additional Information
Specifications are subject to change without prior notice. The document includes typical amplitude response and dynamic range vs. frequency data.
