EFK300 Linear Cable Transducer
- Manufacturer: ELCIS Encoder
- Category: Displacement, SENSORS, Linear Cable Transducer, Linear Transducers
The ELCIS EFK300 is a linear cable transducer with 0.9 mm diameter wire, available in incremental or analog versions, for measuring linear displacements with a useful stroke of up to 3000 mm and a resolution of 0.1 or 1 mm.
Stainless steel cable of Ø 0.9 mm with pull-out and pull-out forces of 7.3 N and 3.5 N. It offers incremental electronics (NPN, PNP, push-pull, 26LS31 or 88C30 driver, TTL 7404, 1 Vpp sinusoidal) or analog electronics (1 kΩ potentiometer, 4÷20 mA, 0÷10 V), max. frequency of 100 kHz, linearity of ±0.05 % fs, max. reading speed of 8 m/s and max. acceleration of 5 G.
IP64 encoder and IP53 mechanical encoder, operates from 0 to 70 °C (storage from -30 to 85 °C) and weighs 1000 g. It is powered from 5 to 30 V according to the code and is connected by 1 m cable, connectors, cable end connectors or Phoenix terminal box, with protection between IP00 and IP67 depending on the connection.
- Maximum useful stroke of 3000 mm.
- Stainless steel cable Ø 0.9 mm; bearing life 1.5 × 10⁹ revolutions.
- Exit incremental (NPN, PNP, push-pull, driver, TTL, sine 1 Vpp) either analog (1 kΩ, 4÷20 mA, 0-10 V).
- Resolution of 0.1 mm either 1 mm with linearity of ±0.05 % fs.
- Maximum reading speed 8 m/s and max. acceleration of 5G.
Technical Frequently Asked Questions
What measurement ranges and resolutions does the EFK300 support?
It allows a maximum useful stroke of 3000 mm, with resolutions of 0.1 mm (code 100) and 1 mm (code 1000).
What electronics and power supplies does the EFK300 offer?
NPN, PNP, push-pull electronics, 26LS31 or 88C30 driver, TTL 7404, 1 Vpp sinusoidal and analog (1 kΩ potentiometer, 4÷20 mA, 0÷10 V), with 5 to 30 V power supply depending on the code. With 88C30 driver, max. 15 Vdc.
What connections and protection ratings does the EFK300 have?
IP64 encoder and IP53 mechanical components; output depends on the connection. Connection via 1 m CV cable (IP65), CM, SM, CL, SL, CD, CH, CH5, CI, CE, C4, and CH6 connectors (IP63 to IP67), cable end connectors (IP65 at the encoder output), or MS terminal box (IP00). Cable, connectors, and cable end connectors support axial or radial (R) output; the MS terminal box supports axial output only.
