Internally Connected Leads (Swaged Leads)
Style SL
Internally connected leads offer maximum flexibility at point of entry to cap, allowing a high degree of flexing as well as the ability to bend the leads sharply adjacent to the cartridge heater.
|
|
|
Straight Braid
Style SB
Stainless steel braid protects leads from abrasion or sharp equipment while allowing flexibility.
|
|
|
Straight Hose
Style SH
Stainless steel hose protects leads from abrasion on sharp equipment while allowing flexibility.
|
|
|
Teflon Leads
Style ST
Internally connected teflon leads seal and resist moisture and oil in applications up to 480°F. This option is available on 1/4" to 3/4" units. A minimum cold section of 5/8" at the lead end is required.

|
|
Internal Sheath Thermocouple
Style JB or KB Cartridge heaters.
Internal thermocouple junction is located adjacent to the inside heater sheath to monitor the part temperature. (JB specifies type "J" thermocouple, KB specifies type "K" thermocouple.) |
|
|
Internal End Thermocouple
Style JC or KC Cartridge heaters.
Internal thermocouple junction is located at the end disc to monitor the material flow past the end of the heater. (JC specifies type "J" thermocouple, KC specifies type "K" thermocouple.) |

|
Ceramic Bead
Style CB
Ceramic bead insulation protects the leads from high temperature environments (above 500°F / 260°C). The beads fit over the solid conductors which extend far enough to reach a cooler area where flexible wires can be attached.
|
 |
|
Right Angle Leads
Style RL
Right angle leads offer high flexibility and are often used when space limitations are critical. Not available with internal thermocouple.
|
|
|
Right Angle Hose
Style NRH Cartridge heater.
Right angle stainless steel hose protects leads from abrasion or sharp equipment and is often used when space limitations are critical. Not available with internal thermocouple. |

Right Angle Overbraid
Style NRB
Right angle stainless steel braid protects leads from abrasion and is often used when space limitations are critical. Not available with internal thermocouple.
|
|
|
Copper Elbow with Leads
Style CE Cartridge heater.
Copper elbow offers right angle exit of leads used when space limitations are not as critical. Available with internal thermocouple. |
|
|
Copper Elbow with Hose
Style CH
Copper elbow with hose for right angle exit of leads with protection against abrasive environment. Used when space limitations are not as critical. Available with internal thermocouple.

Post Terminals
Style PT Cartridge heater.
Post terminals provide a fast, neat connection to ring, spade connectors or bus strips. Threaded 10-24 studs are brazed to the solid nickel conductor. Available only in 5/8", 16.5 mm, 3/4" and 20 mm sizes. |
|
|
Mounting Flanges
Style MF
Mounting flanges may be welded to heater at lead end and is available on all standard diameters. Recommended in applications involving excessive vibration.
|
|
|
