Retired RETIRED

This product has been retired from our catalog and is no longer for sale.

This page is made available for those looking for datasheets and the simply curious. Please refer to the description to see if a replacement part is available.

Replacement: None. We don't have any direct replacement for this part, but check out the rest of our sensor category. This page is for reference only.

Description: The Honeywell HMC105Z is a Wheatstone bridge devices to measure magnetic fields. With power supply applied to a bridge, the sensor converts any incident magnetic field in the sensitive axis direction to a differential voltage output. In addition to the bridge circuit, the sensor has two on-chip magnetically coupled straps; the offset strap and the set/reset strap. These straps are Honeywell patented features for incident field adjustment and magnetic domain alignment; and eliminate the need for external coils positioned around the sensors.

  • this should have been categorized in Sensors\Magneto section

  • Wow… sells for US$17 on digikey…. This is like 70% off!!!! link

  • Yes! 2 of these = digital compass (one for n/s and one for e/w)!!! but it doesn’t fit in breaboard… 50mil pin spacing :(

    …and by the way, Sparkfun: SIP package of this device does not include the offset strap, only a set/reset strap.

    pins are as follows:

    1 GND1(B)

    2 Vo+(A)

    3 Vcc

    4 GND plane

    5 GND2(B)

    6 S/R+

    7 S/R-

    8 Vo-(A)

    So no offset strap. But can anyone figure out why this package has two wheatstone bridges, one of which is disconnected save two GND connections (pins 1 and 5)????

    and this from honeywell is VERY helpful.
