Type N: External Pins with Leads
Flexible stranded lead wires have fiberglass insulation and are connected to 1-1/4″ (32 mm) long solid conductors. Silicone rubber-coated fiberglass sleeving insulates the pin/lead wire connection.
Type F: Internally Connected Flexible Leads
The fiberglass lead wires are internally connected to the terminal pins. This lead termination provides flexibility, permitting the lead wires to be sharply bent as they exit the heater.
Type M1: Polyolefin Liquid Barrier
A liquid barrier used for low-temperature applications primarily in refrigeration or food service applications. The seal bonds to both the heater and the leads.
Type M2: Potted End Seal
Potted end seals help to protect the heater from moisture or contamination from plastic material, cleaning solvents, or oils. The bottom end disc seal is welded in.
Type M3: Teflon® End Plug Seal
A moisture-resistant Teflon® seal that is swaged in during the manufacturing process with Teflon® insulated lead wire.
Type SA: Sealed Corrugated Armor Cable
A liquid-proof stainless steel corrugated metal hose is silver brazed to the end of the cartridge heater. The end disc of the heater is also welded or brazed. This termination provides a positive seal against moisture and contamination entering the heater.
Type S1: Flexible Spring
The leads are reinforced with a steel spring for applications with extreme flexing. The spring is mechanically fastened or silver brazed.
Type W: Wire Braided Leads
Stainless steel braid over fiberglass leads offers sharp bending not possible with armor cable, as well as abrasion protection.
Type W2: Embedded Wire Braid
Stainless Steel braid embedded into seal offers moisture resistance and abrasion protection.
Type W3: Swaged-In Wire Braided Leads
Stainless steel braid over fiberglass leads offers sharp bending not possible with armor cable, as well as abrasion protection. In addition, Type W3 offers contamination resistance due to the Teflon® seal required for holding the wire braid.
Type CS: Straight Armor Cable Directly Attached to Sheath
The armored cable is directly attached to the cartridge heater, eliminating the coupling, to maintain an overall diameter equal to or smaller than the cartridge diameter.
Type C1: Straight Armor Cable with Coupling
Armor cable provides the maximum protection for abrasive, jagged environments. The coupling between the cartridge and the armored cable is mechanically fastened or silver brazed.
*Limited to C1B: SS Cable, Mechanically Fastened for 1/8″ Miniature Cartridge Heaters.
Type R1: Right-Angle Leads with Copper Elbow
This termination is used when space is limited. The copper elbow is mechanically fastened or silver brazed.
Type R2: Right-Angle Leads
This termination is used when space is limited. Not suitable for abrasive environments. Same as C3 and W1 except for plain leads. Various lead end finishes are available as listed below:
Type S2: Right-Angle Spring
The leads are reinforced with a steel spring for applications with extreme flexing. The spring is mechanically fastened or silver brazed.
Type W1: Right-Angle Wire Braided Leads
Stainless steel braid over fiberglass leads for abrasion protection mechanically crimped to the cartridge sheath at 90°. Wire braid offers extreme flexibility not possible with armor cable. Various lead end finishes are available as listed below.
Type C2: Right-Angle Armor Cable with Copper Elbow
Armor cable provides the maximum protection for abrasive, jagged environments. The copper elbow between the cartridge and the armored cable is mechanically fastened or silver brazed.
Type C3: Right-Angle Armor Cable
Use this termination when space is limited and maximum protection is required. The armored cable is tack welded or silver brazed to the cartridge sheath at 90°. The sheath extension is potted with cement. Various lead end finishes are available as listed below.
Type T2: Screw Terminals
For use with leads, crimp terminals, or bus bars. Includes washers and nuts.
Type B: Heat Resistant Ceramic Bead Insulation
The ultimate in high-temperature lead protection. Allows for the attachment of flexible leads to the heater away from the high heat area. Used when the ambient temperature exceeds 842°F (450°C).
Type BL: Heat Resistant Ceramic Bead Insulation with Leads
High-temperature flexible leads are connected away from the high heat area.
Type T4: Double-End Terminal Pin
For those applications in which wiring from both ends is an advantage. Various seals are available:
Type F1: Double-End Flexible Leads
For applications in which it is an advantage to wire from both ends. The leads are internally connected and can be bent sharply as they exit the potted ends. Various seals are available:
Type T3: Double-End Screw Terminal Leads
A Double-Ended heater with quick-change wiring screw terminals. Includes zinc-plated washers and nuts.
