DN6838 is a bipolar Hall‑effect switch sensor manufactured by Panasonic, packaged in 3‑pin SIP through‑hole form factor. The chip integrates Hall element, amplifier and comparator circuit inside, responds to alternating magnetic field from small permanent magnet and outputs digital switching signal.

Operating supply voltage ranges from 4.5V to 12V. Operating magnetic flux density is 300Gauss. Wide temperature range from ‑40℃ up to +100℃ fits harsh working environment. Output stage can directly interface with DTL, TTL and MOS‑level ICs, no extra driving circuit required. Contact‑less magnetic detecting brings nearly unlimited service life compared with mechanical switches.

Pin definition: Pin1 Vcc, Pin2 GND, Pin3 Output. Widely used for motor rotation detection, rotary encoder, position detection, proximity trigger switch for home appliances and industrial equipment. Correct mounting and matched magnet are required for stable performance.
