Honeywell T12-A118 Inductive Proximity Switch Sensor

Honeywell T12-A118 Inductive Proximity Switch Sensor detects metal objects without contact, using inductive sensing with a 12 mm sensing distance. The T12-A118 is used in industrial automation and machine control to provide a non-contact metal-detection signal that can drive control logic. As part of Honeywell's line of inductive proximity sensors, this model shares the characteristic 12 mm sensing range and is identified by the T12-A118 designation for appropriate integration with compatible control hardware. The 12 mm sensing distance supports sensing metal targets in tight spaces where mechanical switches are impractical, reducing wear on moving parts compared with contact sensors. Typical uses include end-of-travel sensing, position indication, and interlocking in automated equipment where metal presence within the sensing field indicates a state change in the system.
