To provide an elevator car position detection sensor capable of suppressing erroneous detection of presence or absence of a plate. The elevator car position detection sensor includes a first coil provided to one of an elevator car and a hoistway and configured to output an excitation magnetic field to a plate provided to the other of the elevator car and the hoistway; a second coil provided on an opposite side of the first coil relative to the plate; a shield wall configured to shield an end portion of the plate located closer to one of the car and the hoistway; and a determination circuit configured to determine a phase of an alternating-current voltage corresponding to a frequency of the excitation magnetic field output from the first coil at an alternating-current voltage generated across the second coil.

A safety monitoring device monitoring safety-related states in a passenger conveyor system has first and second double contact relays each controlled by a control voltage to switch first and second normally open contacts and a feedback contact synchronously between an open and closed relay states. First and second controllers each determine properties of the system correlated with safety-related states and in dependence generate the control voltages. The controllers and two double contact relays form first and second safety monitoring switch arrangements for monitoring first and second safety-related states and correspondingly switch first and second switching states within a safety monitoring chain of the system. The first arrangement includes the first contact of the first connected in series with the first contact of the second relay. The second arrangement includes the second contact of the first relay connected in parallel with the second contact of the second relay.
