This is the TP2SM touch probe #A-1041-7541. The TP1SM is similar to TP1S, but with the cable connector rotated 90°.
The TP1S/TP1SM is a 1 inch diameter, shank mounted probe that is ideal for manual CMMs due to its robust design and large overtravel range. The probe signal is carried to the CMM via an external cable, and the probe has an adjustable stylus force to help optimise its performance. It has an M3 stylus mount and can carry a wide range of styli. These robust and reliable probes are especially suited for manual CMMs. They are available in two versions with differing plug socket orientations: TP1S cable connects vertically TP1SM cable connects horizontally
