Magnetic detector instrument with board-mounted sensor assembly
First Claim
1. A magnetic detector instrument comprising a substantially planar elongate circuit board supporting electronic components of the instrument and constituting a sensor support, an elongate magnetic sensor assembly having a magnetic axis along its length, and means mounting the sensor assembly on the support including a slot having an open end at one end of the support and a pair of opposed longitudinally extending external grooves formed in the sensor assembly, said sensor assembly fitting longitudinally into said slot through its open end, with the magnetic axis along the length of said circuit board and with slot-defining edge portions of the support received in the respective grooves whereby the sensor assembly is retained in the slot.

Abstract
A magnetic detector instrument includes an elongate circuit board and a magnetic sensor assembly which slides into a slot in one end of the board with edge portions of the board defining the slot being received in opposed elongate grooves formed in the sensor assembly. Also, a fitting for retaining the board while it is rotated in order to set the alignment of the sensor core includes elongate brackets with opposed grooves into which the circuit board slides.
