Assembly Notes: When using either styles OB190 or OB250, it is an advantage to inter-connect with either a plug and socket or a terminal strip. This connection is usually made adjacent to the bearing assembly, thus allowing the probes to be withdrawn and replaced without disturbing the extension leads running through the machine.

Please note: These connectors are also available with copper conductors suitable for PRT assemblies.
