Allen-Bradley Sensors

Allen-Bradley sensors in this collection include photoelectric devices such as 42EF RightSight and 42KL MiniSight, ultrasonic 873P proximity sensors, 440N SensaGuard / Guardmaster non-contact safety switches, and related QD cordsets. Catalog prefixes identify the sensing family—42EF and 42KL for photo, 873P for ultrasonic, 440N for non-contact safety—so matching that prefix to the failed unit is the fastest path to a like-for-like replacement. Confirm sensing mode, connector style, and sensing distance against the old part before ordering. Note: this collection handle historically referenced limit-switch arms, but the live products are sensors; limit arms live under the dedicated 802T arms collection. East Coast Compactor ships common sensors from Northwood NH. ECC is not an authorized Rockwell distributor and does not offer manufacturer warranty claims.
