ABSTRACT:
A proximity switch adapted to be threaded into a pressure cylinder, with the proximity switch including a sensor part insertable into a bore or opening of a cylinder wall of the pressure cylinder for detecting a position of the piston. A housing of the proximity switch includes a metal casing for accommodating a sensor part of the proximity switch, a front cap for sealing the metal casing, an a housing section attached to the metal casing and including a cable connection portion. A continuously extending output collar is provided at a rear end of the metal casing, with the collar being adapted to be fixedly clamped against the cylinder wall by a mounting gland extending behind a rear face thereof or by a coupling ring.
