DEFINITION

Classification: 83/62

(under subclass 58) Device in which the signal or impulse is generated by a detector* which directly or indirectly senses a condition or location of the tool or of the work-moving means.

(1) Note. The direct contact of the detector with the tool or work-moving means may be that which occurs in the normal, uninterrupted operation of the device, in which case the signal for stopping is generated by failure of the detector to make such direct contact.
