Claim 12:
13. Sensor configuration (1) for non-invasive measurement of parameters of a body tissue, the sensor configuration comprising:
a sensor unit (10),
a sensor mat (12) for detachable placement of the sensor configuration (1) on a body surface (20) having the body tissue, and
a contact head (16) detachably attached to the sensor unit (10),
wherein:
the sensor unit (10) comprises:
(a) a flexible printed circuit board with conducting tracks (5) and a longitudinal axis (18),
(b) at least one light detector (2) for detecting light that has been emitted into the body tissue and has passed through the latter, and
(c) an annular shaped first contact (30) having electrical contact points and magnetic contact portions, each arranged in a first contact geometry for operative connection of the sensor unit (10) to the contact head (16),

the sensor mat (12) has a multi-layered structure comprising:
(a) a lower layer (13), having a lower contact surface for contact on the body surface (20) and an upper contact surface for support of the sensor unit (10), whereby openings (15, 17) are provided which are aligned with respect to the at least one light detector (2) of the sensor unit (10), and
(b) an upper layer (14), which is connected to the upper contact surface of the lower layer (13) in a way detachable from one another, and

the contact head (16) comprises:
(a) a ring-shaped second contact configured as an annular printed circuit board comprising contact pins as second electrical contacts and tin points as second magnetic contacts, each arranged in a second contact geometry that corresponds to the first contact geometry,
(b) a housing (40) for accommodating the ring-shaped second contact, and
(c) a cylindrical internal light source (70) made of a light-conducting material with a light-emitting surface (22) for guiding light from the internal light source.
