Schneider Electric 9007TYD5 Limit Switch

Schneider Electric’s Square D 9007TYD5 limit switch is an electromechanical position sensor that delivers discrete signals to control panels, PLCs, contactors, or alarms when a machine part reaches a set position or end of travel. It uses a roller lever actuator and typically provides SPDT (1 NO + 1 NC) or DPDT contacts depending on actuator style. Electrical ratings include up to 600 VAC or 250 V DC (model dependent) and industrial-control current on the order of 10–15 A. Terminations are screw-type, and mounting is panel or machine surface. Housed in a rugged industrial enclosure for standard industrial operating conditions, it is suited for use in manufacturing automation, material handling, packaging lines, lift/transfer systems, and safety interlock circuits to detect movement and trigger appropriate control signals to PLCs, contactors, or alarms. Common deployment includes conveyor ends, machine guard doors, presses, indexing tables, and other automated equipment where discrete limit detection drives stops, reversals, or state changes in control sequences. Common replacements include Square D 9007TYG5, Allen-Bradley 802T-A, and Omron D4MC-5020.
