Mica cores produce thin, efficient heaters. All full mica band heaters are designed with closed ends to protect against contamination. Sheath temperatures of up to 800 F are possible. Mica bands are available with many different mounting and wiring options, including: fiberglass, ss-braided or armored leads, screw terminations, terminal protection hardware, and several types of mounting clamps.

Termination Types:
Fig. 1: Usual design for nozzle heating applications. 12" leads are standard. | Fig. 6: Flexible armor cable is the best solution to lead abrasion problems. 12" armor with 14" overall length leads are standard. Specify alternate position. | ||
Fig. 3: Single conductor metal braid over lead wire. Offers most practical solution to abrasion problem. 12" braid with 14" overall length leads are standard. | Fig. 7: Double conductor metal braid exiting from edge 180° from gap. | ||
Fig. 4: Standard lead wires exiting 180° from gap. | Fig. 16: Double conductor metal braid over lead wires at same position as Fig. 5. 12" braid with 14" overall length leads are standard. Specify alternate position. | ||
Fig. 5: Leads exit at right angle to sheath 5/8" from gap. 12" lead wire in 3" long sleeving is standard. Specify alternate position. |
|
Fig. T1: Standard position under 2-1/2" wide. | Fig. T2: Standard position over 2-1/2"wide. | |
|
Fig. T3: Standard with terminal box. | Fig. B1 (shown) B2, B3: 10-32 thread requires 1/2" clearance from cylinder. |
