Honeywell MICRO SWITCH CX Series Limit Switches

MICRO SWITCH CX Series Limit Switches are built especially for outdoor use in hazardous atmospheres. These enclosures are constructed to withstand the pressure of an internal explosion. Flame paths cool the exploded gases to a point less than safe operating temperature of the surrounding gas.

MICRO SWITCH 80CX Series switches have rugged bronze housings that are designed to be resistant to salt water and other corrosive environments. They comply with the NEMA 4X requirement for protection against corrosion, in addition to NEMA enclosure standards met by other CX switches.

The product's o-ring seals make the enclosure rain tight, but are outside of required flame paths so explosion proof requirements are maintained. Unless special ordered, all basic switches operate on clockwise and counterclockwise rotation. The actuating mechanism can be field adjusted for CW or CCW operation only. No tools are required.


Details

Features

1.Explosion‑Proof & Hazardous Area Design

Engineered for Class I, II, III hazardous locations (Div 1 & 2); enclosure withstands internal explosion pressure; flame paths cool gases to prevent ignition.

2.Rugged Corrosion‑Resistant Housings

Die‑cast aluminum (standard) or bronze (80CX series) with NEMA 4X corrosion protection; ideal for saltwater, chemical, and harsh industrial environments.

3.Superior Sealing Performance

IP66/IP67 and NEMA 1, 3, 4, 4X, 6, 6P, 13 ratings; O‑ring seals ensure watertight, dust‑tight, and weatherproof operation.

4.Tool‑Free Field Adjustability

Pretravel, overtravel, and actuating sequence adjustable on‑site; rotary heads configurable for CW, CCW, or dual‑direction operation without tools.

5.Precision Snap‑Action Contacts

SPDT, DPDT, 4PDT configurations; double‑break design for fast, positive, and repeatable switching.

6.Wide Electrical Ratings

Up to 15A @ 480V AC; 0.5A @ 250V DC; suitable for heavy‑duty industrial control circuits.

7.Extensive Actuator Selection

Side rotary, top plunger, roller lever, adjustable lever, and wobble lever options; compatible with various position‑sensing requirements.

5.Flexible Mounting & Wiring

Standard screw mounting; 3/4"‑14 NPT conduit entries for secure wiring; captive screws simplify installation.

6.Wide Operating Temperature

–25°C to +85°C (–13°F to +185°F); low‑temp variants available to –40°C for extreme environments.

7.Long Service Life

Mechanical life up to 10 million cycles; electrical life up to 500,000 cycles for reliable long‑term operation.

8.Global Hazardous Area Certifications

UL, CSA, ATEX, IEC Ex, INMETRO, CE, and RoHS compliant for worldwide use in explosive atmospheres.

9.Built‑in Safety Features

Internal grounding provisions; sealed conduit connections for enhanced electrical safety.
