ARCJ1AZ0 - 

ARCJ Ring Adapters can be quickly and easily installed on foot-mounted motors with NEMA type “C" face mount end bells, or between motor and gear case flange. The ARCJ ring, with integral junction box, is cast aluminum with precision machined mounting surfaces. Kits are supplied complete with a 60-tooth sensing gear, factory installed magnetic pickup or HESS sensor, and mounting hardware. The maximum recommended gear speed for all kits is 5,000 RPM. Two ARCJ ring sizes and five gear bores cover the range of motor frame sizes as listed in the Ordering Information. Wiring connections to the sensor are made by removing the gasketed junction box cover. Two threaded female (1⁄2" NPT) conduit connections are provided for right or left conduit entry (as shown in the Dimension drawing). A threaded plug is supplied with each kit for sealing the un-used conduit entry. The 60-tooth steel sensing gear (kit supplied) results in direct RPM indication when used with a 1 second time-base rate indicator (tachometer). Red Lion Controls rate indicators can be configured to provide a complete speed sensing and indication system. The following two sensor options (next page) are available with the ARCJ kits in order to meet a wide variety of applications.
