Product details

Active Hall Switch – Dual-Pole Sensing in a Through-Hole Package

The Infineon TLE4941CN is a Hall-effect magnetic switch that detects both north and south pole fields, making it suitable for speed and position sensing in rotating or linear applications where the magnet polarity alternates. It operates from a 4.5 V supply rail and delivers a current-source output rated at 16.8 mA switching current, enough to drive a small relay coil or a PLC input directly without a buffer transistor.

Temperature Grade and Environment Fit

Rated for -40°C to 125°C (TA), the TLE4941CN covers automotive under-hood and industrial outdoor enclosures where the ambient temperature swings wide. The through-hole package (Bulk) is a practical choice for prototyping or low-volume production – the leads are robust enough to survive a rework cycle without lifting a pad.

Sourcing Reality – Active Production, No Obsolescence Pressure

No last-time-buy deadline or successor part is recorded.

Frequently asked questions

Can the TLE4941CN detect both north and south poles?

Yes – the device is polarized for both North Pole and South Pole detection, so it responds to either magnetic field direction. This makes it a bipolar Hall switch, not a unipolar one.

What is the output current of the TLE4941CN?

The switching current is rated at 16.8 mA, which is the current-source output capability. It can drive a small relay coil or a PLC input directly.
