Turck C4A40X120VAC Capacitive Proximity Sensor

Turck Comat Releco C4-A40X/120VAC is a four-pole changeover power relay in a socket form factor, designed for industrial control and automation panels. The coil is rated for 120 VAC, enabling direct interfacing with standard AC control circuits, while each of the four Form-C contacts provides a normally closed and normally open path per pole for independent switching of four loads, with a practical current capability up to 10 A. This C4-A40X model sits in Turck’s Comat Releco family as a plug‑in relay, enabling quick replacement and modular wiring in control cabinets. Typical uses include isolating and interlocking AC loads, coordinating multiple actuators in automation sequences, and simplifying panel wiring in complex control circuits, all within a compact 4PDT configuration. The part number C4-A40X/120VAC denotes the 120-volt coil variant of the 4PDT C4 family, and its socket-compatible design ensures reliable mating with Turck-recommended socket bases for robust, maintenance-friendly operation in demanding industrial environments.
