WS-HEATER

Supported Applications

The OMEGALUX® WS series strip heater is designed for general-purpose heating applications requiring a standard width of 2½" (6 cm). The product overview identifies these heaters as suitable for most strip heater applications where rugged, reliable performance is required. They are offered with side-by-side terminals placed at a right angle on one end.

Operating Conditions & Performance

The WS series operates from 120 or 240 Vac power supplies and delivers output ratings ranging from 400 to 1500 watts. Maximum sheath temperatures depend on the selected material: Iron supports up to 399°C (750°F), while Chrome Steel supports up to 649°C (1200°F). Watt density varies by model, with values listed in specifications ranging from 8 W/In² to 25 W/In². The series carries CSA Certified, UL, CE, and VDE approvals.

Key Performance Parameters

• Power Supply: 120 or 240 Vac
• Wattage Range: 400 to 1500 watts
• Maximum Sheath Temperature (Iron): 399°C (750°F)
• Maximum Sheath Temperature (Chrome Steel): 649°C (1200°F)
• Width: Standard 2½" (6 cm) as shown in diagram; also noted as 2½" (6.4 cm) height dimension.

Model-Specific Dimensions and Ratings

The series includes multiple model numbers with varying lengths, mounting hole counts, wattages, and weights:

• WS-640/*: 6½" (17) length A; 5½" (14) B dimension; 2 mounting holes; 400 watts at 14 W/In².
• WS-850/*: 8½" (22) length A; 7½" (19) B dimension; 3 mounting holes; 500 watts at 16 W/In².
• WS-1260/*: 12" (30) length A; 11" (28) B dimension; 4 mounting holes; 600 watts at 12 W/In².
• WS-1575/*: 15¼" (39) length A; 14¼" (36) B dimension; 6 mounting holes; 750 watts at 11 W/In².
• WS-2185/*: 21" (53) length A; 20" (51) B dimension; 9 mounting holes; 850 watts at 8 W/In².
• WS-2510/*: 25½" (65) length A; 24½" (62) B dimension; 11 mounting holes; 1000 watts at 8 W/In².

Additional models include WS-605/*, WS-806/*, WS-1208/*, WS-1501/*, WS-2101/*, and WS-2515/* with wattages ranging from 500 to 1500 watts.

Ordering Configuration

Voltage is designated by inserting "120" for 120 Vac or "240" for 240 Vac into the model number (e.g., WS-1575/240). Standard heaters include two mounting holes; models with higher wattage may require No. 10-32 Thread Over 3000W as noted in diagrams, though specific thread details are not defined in text.

Configuration Options

The WS series is configurable across sheath materials (Iron or Chrome Steel), voltage options (120 Vac or 240 Vac), and physical dimensions corresponding to model numbers. Optional accessories include:

• Type SE-AC-1 terminal housing, mounted sideways for use with WS strip heaters.
• Ceramic post terminal insulators as an optional component.

Mounting hole configurations vary by model: standard units have two mounting holes; larger models feature 3 to 11 holes depending on length. Hole diameter is noted as 21/64" for certain options, though this applies specifically where indicated in documentation.

Key Product Differences

Differences among WS series variants are primarily defined by model number, which dictates overall dimensions (A and B), wattage output, watt density, weight, and mounting hole count. Sheath material selection determines maximum operating temperature limits: Iron sheaths max out at 399°C (750°F); Chrome Steel reaches 649°C (1200°F). Voltage designation is appended to the model number suffix.

Weight increases with size and power rating, ranging from 0.75 lb (0.3 kg) for WS-605/* up to 2.63 lb (1.2 kg) for WS-2515/*. All models maintain a consistent width of approximately 2½" but differ in length A dimension and associated mounting requirements.
