MA3
US Digital MA3 — Linear Position Sensors Angle Sensors
Manufactured by US Digital, the miniature MA3 is a contactless Hall-effect absolute singleturn magnetic encoder featuring a 12.2 mm housing diameter and a 360-degree electrical angle. Operating on a 4.5 to 5.5 V DC supply voltage, this bushing-mounted component provides 0 to 5 V DC or PWM output signals across a temperature range of -40 to 125 °C. Shaft diameters are available in 3.2, 6, and 6.4 mm supported by a ball bearing and metal sleeve, drawing 20 mA of current with a linearity of ±0.14% FS. Please submit the exact part number, quantity, and application requirements to receive a formal quotation for this superseded model.

Request a QuoteWhy no listed price?
Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued US Digital references — within one business day.
