The GE IC9445A200AB, also cataloged as the IC9445A200AB Limit Switch, operates as a dedicated hardware component for mechanical position sensing and physical travel limit execution within industrial machinery control circuits.

Hardware Specifications

I/O Density Scaling & Backplane Bus Integration

When integrated into automated control systems, the IC9445A200AB provides discrete physical contact status feedback directly to digital input modules or hardwired safety interlocks. The heavy-duty 2-circuit contact block ensures rapid mechanical break/make operations, maintaining signal integrity and determinism across high-density I/O networks. High contact pressure and robust internal wiping actions mitigate contact bounce, preventing false input triggers and frame register errors on remote backplane bus communication cards.

Frequently Asked Questions

Q: Are the contact blocks in the IC9445A200AB limit switch electrically isolated?

A: Yes. The 2-circuit contact assembly provides double-break, electrically isolated contacts allowing independent control of separate AC or DC signal loops.

Q: Can the operating lever head be rotated to suit different mechanical actuation directions?

A: Yes. The heavy-duty actuator head assembly can be indexed and mounted in 90-degree increments to accommodate various physical stroke angles and mechanism travel directions.

Q: What type of conduit entry does the IC9445A200AB enclosure feature?

A: The switch housing includes standard threaded NPT conduit entry hubs to facilitate liquid-tight cable gland and rigid metal conduit connections.

Field Installation Guidelines

1. Isolate all control loop voltages feeding the limit switch contacts and lock out power to the mechanical motion equipment before beginning installation.
2. Mount the heavy-duty switch body securely to a rigid machine surface using appropriate mounting bolts to withstand mechanical impact and vibration.
3. Adjust the operating lever arm position so that the target cam engages the roller/lever within its specified mechanical travel arc without bottoming out the actuator shaft.
4. Route field wiring through the threaded conduit opening using appropriate NPT fittings, ensuring thread engagement meets standard industrial sealing requirements.
5. Terminate incoming control conductors onto the internal 2-circuit screw terminals and securely tighten the enclosure cover gasket to maintain environmental seal integrity.
