Fits dual magnetic-pickup flow or speed signals where you need a KEP AMP-2—two independent differential preamps with 10 mV p-p sensitivity, 0–4000 Hz bandwidth, and open-collector pulse outputs.
Key advantages
- Channels — Dual independent mag-pickup inputs
- Sensitivity — 10 mV p-p; 0–4000 Hz
- Power — 8.5–30 VDC; ~25 mA; reverse/surge protection
- Output — Open-collector with 10 kΩ pull-up; ≥20 mA sink
- Env — −40…+65 °C
Typical applications
- Dual turbine pickup conditioning.
- Long-cable mag-pickup runs.
- Ratemeter / counter front-ends.
Selection guide
- Cable length / shielding
- Host input type
- Supply voltage
Common mistakes
- Overloading open-collector beyond rating.
- Single-ended wiring on differential inputs.
- Ignoring 4000 Hz bandwidth.
When to RFQ / what to tell us
- Supply, host type.
- Quantity, ship-to.
