Official Part Number D4C-1201
GTIN Standard 4536853210052

Technical Overview

The Omron D4C-1201 is a highly durable, compact enclosed vertical limit switch engineered for rigorous industrial environments. It features a robust 10mm diameter stainless steel pin plunger actuator and a 1NO+1NC (SPDT) contact configuration. Encapsulated with a triple-sealed construction to meet an IP67 degree of protection, this switch offers exceptional resistance to oil, water, and dust. This resistance is further supported by a pre-wired 3-meter VCTF oil-resistant 4-core cable. Delivering precision position detection capabilities with an operating force of 11.77N and a minimal 0.2mm movement differential, it is highly suitable for integration into automated machinery, machine tools, and heavy-duty packaging equipment requiring reliable, high-accuracy signaling.

Key Features

Industrial Applications

1. CNC Machine Tool Positioning

Detecting the precise home position or end-of-travel limits for milling axes in CNC machining centers.

Problem Solved

CNC machines require exact feedback for tool positioning while operating in environments heavily sprayed with coolant fluids and metal swarf. The D4C-1201's triple-sealed IP67 rating and oil-resistant VCTF cable prevent coolant ingress and short circuits, while the tight 0.2mm movement differential ensures highly repeatable precision.

2. Automated Packaging Conveyor Gates

Confirming the closed position of heavy-duty diverter gates on high-throughput automated packaging lines.

Problem Solved

Continuous diverter actuation requires a switch that resists mechanical wear and reliably signals a PLC when a gate successfully snaps shut. The robust 10mm stainless steel pin plunger withstands high-cycle physical impact, and its 11.77N operating force ensures only deliberate actuations register, avoiding false triggers from line vibration.

3. Industrial Hydraulic Press Safety Interlocks

Monitoring the physical seating of dies or safety guarding prior to initiating a high-pressure press cycle.

Problem Solved

Stamping and hydraulic presses generate significant mechanical shock and operate in greasy environments. The 5A/250VAC electrical rating allows this switch to directly interlock with safety contactors. Meanwhile, its rugged, compact vertical housing fits perfectly into confined die spaces without succumbing to surrounding hydraulic fluids.
