    摘要: A switch module used for position sensing may be operated in a number of modes for compatibility with a number of legacy position sensing products. A dry switch circuit can be configured to provide a direct output, emulating dry reed, high- side or low- side switched configurations. Alternatively, the dry switch circuit can be connected to an input of a NAMUR circuit to provide the known current output for that standard. In another configuration the dry switch can be selectively coupled to one of two NAMUR circuits allowing the switch module to provide a low-to-high current NAMUR output or a high-to- low current NAMUR output.

    摘要: A magnetically-triggered proximity switch includes a cylindrical switch body and a bias member non-movably secured within the switch body. The proximity switch also includes first and second normally-closed contacts and first and second normally-open contacts. The proximity switch further includes a spherical contact magnet disposed within the switch body, with the contact magnet being movable relative to the bias member from a first switch position and a second switch position. In the first switch position, an attraction to the bias member maintains the contact magnet in contact with the first and second normally- closed contacts, thereby completing a circuit between the first and second normally-closed contacts. In the second switch position, an attraction to a movable target external to the switch body moves the contact magnet into contact with the first and second normally-open contacts, thereby completing a circuit between the first and second normally-open contacts.

    摘要: Proximity switches are disclosed that preferably are provided in a hermetically sealed unit that can be used in harsh environments and under significant pressures, such as underwater and in nuclear power facilities, without having any parts that would require replacement or periodic maintenance. The proximity switches are preferably switches actuated by physical movement of a contact in response to changing magnetic forces. The switches are preferably disposed in a body tube optionally including a hermetic seal assembly to seal an open end of the body tube and/or a ferrule that prevents electrical wires attached to the switch inside the body tube from being pulled away from the switch. Further, the switches preferably maintain a contact pressure between electrical contacts sufficient to withstand acceleration seismic testing of 10g with no contact discontinuity.
