Screw Terminals and Box Protection:
1/4-20 x 1" threaded terminals are standard as in Fig. S or in terminal box as in Fig. B. Under 2" width, terminals are parallel to circumference. Over 2", terminals are perpendicular to circumference. Standard position is 180° from gap. Specify alternate position.

Braid or Conduit Protection:
To protect leads against abrasion, braided sleeve in Fig. L. is held in place by a clip. Conduit in Fig. A is connected to stand off bracket. Standard position is 180° from gap. Specify alternate position. Standard length is 12" braid or cable with 14" leads.

Overlap Flange:
For thermocouple probe hole located through gap as per Fig. F.
Leads:
Fiberglass insulated lead wires held in place by a clip as per Fig. D. Standard position is 180° from gap. Specify alternate position.

Quick Disconnect Plug:
U.L. approved plugs can be attached with Bracket­Fig. P; Conduit­Fig. A and C; Braid­Fig. L. Mighty-Miser Ceramic Band Heaters can also be supplied with #110 European Plug. Other plugs attached to leads are available.

CERAMIC BAND HEATER WITH BLOWER
A perforated rather than insulated shroud with a cowl, plenum and blower is designed for use on plastic extrusion equipment where some processes generate excessive heat from pressure. When a predetermined temperature is exceeded, the blower will engage, cooling the process. Consult Ogden with application requirements.

Maintenance and Trouble Shooting for Prolonged Heater Life: 1. Regulate Voltage. A 10% variation in voltage results in a 20% variation in power. 2. The cylinder must be clean and smooth for efficient heat transfer. 3. When attaching the lead wires to the terminals, excessive turning pressure can cause breakage of the terminal resistance wire. 4. A 12" gap should be maintained at the opening when operating. Retightening is not normally required, however, if the operating temperature is changed, the flange bolt should be checked. 5. Oil, plastic, dirt, etc., should not be allowed to accumulate on the heaters. 6. Select a heater to match the diameter of the cylinder. 7. Match the heaters as closely as possible to the actual load requirement.
