SS361CT SOT-23 Pinout

Notes

• Package: SOT-23 (3-pin surface-mount)
• Output Type: Open-drain (current sinking). Output is pulled low when magnetic field condition is met; external pull-up resistor required for logic-level output.
• Supply Voltage: 4.0–24.0 Vdc
• Magnetic Activation: SS361CT responds to North pole (Bop = 50 G typical at 25°C)
• ESD Sensitivity: Class 1C — handle with care at static-free workstation
