Coil 080, 092
The 1mm Decisive Difference:
AirTAC 080 & 092 Coil Field Guide
Imagine the scenario: a critical production line is halted due to a burnt-out solenoid coil. A technician secures what looks like an identical AirTAC replacement, only to find it physically impossible to install. This costly downtime is usually the result of the 1-millimeter difference between the 080 and 092 series.
While they share electrical connectors and voltage options, they are completely non-interchangeable. This is a deliberate "mechanical lock" designed to ensure that specific valve platforms receive the exact electromagnetic force required for their volumetric flow.
- Mechanical Incompatibility: The 080 series utilizes an 8.0mm bore; the 092 series utilizes a 9.0mm bore. swappability is physically blocked.
- The "Compact" Tier (080): Dedicated exclusively to 100-Series valves (e.g., 4V100), optimized for tight footprints and precision robotics.
- The "Mainstream" Tier (092): The industrial workhorse for 200, 300, and 400 Series valves, delivering the torque needed for high-flow spools.
- Cv-Driven Selection: Choice is dictated by flow horsepower. 080 serves low-flow apps (C≈0.67); 092 serves high-flow apps (Cv ≥ 1.0).
- Unified Industrial Ratings: Both series standardized to IP65 weatherproofing and 100% ED continuous duty.
1. The Mechanical Lock: 8.0mm vs. 9.0mm
The distinction between these two series is a physical safeguard for your machine's logic:
080 Series (8.0mm Bore)
Platform: CDA080 / CLA080
Compatible Valves: 100 Series (4V100, 3V100).
Power Class: approx. 2.5W～2.8W (DC24V).
Purpose: Precision control for small-bore cylinders in space-constrained enclosures.
092 Series (9.0mm Bore)
Platform: CDA092 / CLA092
Compatible Valves: 200, 300, 400, & ESV Series.
Power Class: approx. 3.0W (DC24V).
Purpose: Mainstream factory automation requiring higher spool torque and volumetric flow.
2. Logical Selection: Flow over Coil
Engineers do not choose a coil; they choose a Flow Coefficient (Cv). The coil is merely the result of that performance requirement:
Step 1: Identify Actuator Volume
If the cylinder is small (M5/1.8" ports), specify the 4V100 Series. This dictates an 080 Series Coil (8.0mm).
If the cylinder requires rapid speed and power (1/4" ports +), specify the 4V200/ESV Series. This dictates a 092 Series Coil (9.0mm).
3. Common Industrial DNA
Despite mechanical separation, AirTAC standardizes critical reliability features across both platforms:
IP65 Environmental Shielding
Dust-tight and protected against water jets from any direction. Built for factory wash-downs and heavy coolant spray environments.
100% ED Continuous Duty
Engineered for 24/7 energized states without overheating. Essential for fail-safe clamping logic that must hold indefinitely.
Technical FAQ
"Can I force a 092 coil onto a 100-series valve?"
No. Even if you manage to sit it on the stem, the magnetic flux gap will be incorrect. This leads to weak shifting or coil burnout. Use the 080 for 100-series; no exceptions.
"My DC indicator light isn't on, but the valve works?"The coil is non-polarized, but the LED connector is. You have wired the DC polarity backwards (Pin 1 should be positive). Swap the wires to restore visual diagnostics.
The 1mm Insurance Policy
The difference between 080 and 092 is a deliberate engineering barrier. By physically preventing the installation of low-flow coils on high-torque valves, AirTAC ensures your system performs exactly to its Cv design specifications. Start with your flow requirements, and the correct 1mm choice will follow automatically.
