KGEA-WT_14 Datasheet, PDF (1/1 Pages) PREMO CORPORATION S.L – Keyless go emitter antenna winding heat shrink tube

KGEA-WT
(33 µH - 500 µH)
Keyless go emitter antenna winding heat shrink tube
Characteristics
This part can offer the possibility to welding directly on PCB or the
customer directly over-molded for different applications of readers RF
antennas and thus far reducing cost. The emitter antenna is covered by
heat shrink tube to avoid handling problems.
- High reading distance depending on the different sizes of the ferrites.
- Designed for a range of working frequency LF
(20kHz, 125kHz and 134,2kHz).
- Antenna current. Max. 4 App, Duty 30%
- High stability in temperature (-40ºC to +85ºC).
