RP-1 EBW Detonator​

P/N 167-4314​ ​-  Dow​nloa​d a​s PDF​                           
​​The RP-1 is a high precision Exploding Bridgewire Detonator manufactured by RISI which features close tolerance electrode spacing, precise bridgewire attachment, high quality loading sleeves and a rigidly controlled crystallization process of the PETN explosive and loading operation. Density is controlled through consistency of crystalline structure, precision weighing and class ‘A’ dies and tooling.

The result is a detonator with a transmission time simultaneity standard deviation of less than .025 microsecond. While some applications may not require this degree of timing or safety, users may want to take advantage of the high degree of reliability​.

Caution: While EBW and EFI Initiators are inherently less susceptible to accidental detonation during handling and set-up than devices containing primary explosives, electrical and electronic firing systems are sensitive to transient electrical energies which could cause premature triggering or firing. The blasting area must be clear of personnel and equipment before the detonator leads are connected to any RISI Firing System. Only approved RISI Firing Systems should ever be used to initiate or detonate any explosive product manufactured and authorized for sale by RISI.​

The RP-2 is a high precision Exploding Bridgewire Detonator manufactured by RISI which features close tolerance electrode spacing, precise bridgewire attachment, high quality loading sleeves and a rigidly controlled crystallization process of the PETN explosive and loading operation. Density is controlled through consistency of crystalline structure, precision weighing and class ‘A’ dies and tooling.

​​RP-3 EBW Detonator​

P/N 167-9225​ - D​ownload​ as PDF​

​The RP-3 EBW detonator is a miniature detonator containing less than 30 mg of PETN explosive. Although small this detonator will initiate most common military explosives. The RP-3 is used in situations which cannot tolerate blast or fragment damage but still requires the safety and reliability of an EBW detonator.

​RP-83 EBW Detonator​

P/N 167-8676​ - D​ownload ​as PDF

The RP-83 is a stretched version of the RP-80 detonator and contains over 1 gram of high density explosive in the output. The RP-83 is capable of detonating all standard explosives and many blasting explosives.

 

 

​RP-85 EBW Detonator ​

P/N 188-7080​ - D​ownload as​ PDF

The RP-85 detonator has the same output as the RP-83, however it is sealed for under-water use. All RP-85 detonators are individually tested to 1000 psi water pressure.

 

 

​RP-87 EBW Detonator​

P/N 167-9643​ - D​ownload​ as PDF

The RP-87 explosive is contained in a 0.006" thick stainless steel case which is crimped onto the plastic head. It is for use where small size is important. The RP-87 is similar to the MK 71 detonator in geometry and output except it contains no primary explosive.

 

 

​​​RP-501 Economy EBW Detonator​

P/N 188-7359​ - D​ownl​oa​d as PDF​ - Product Alert, Click Here​​​

The RP-501 is an EBW detonator for use in general purpose applications where the added safety of secondary explosives is desired and where cost is the paramount consideration. There is a distinct trade-off between price and performance; therfore, the user should carefully examine the performance specification of this detonator before selecting it for an application. For the purpose of performance comparison, refer to the RP-1 and RP-2 detonators which are also shown in this catalog. The RP-501 is a standard, end lighting detonator capable of detonating compressed TNT and COMP B.

 

​RP-502 Economy EBW Detonator​

P/N 188-7410​ - D​ownload a​s PDF - Product Alert, Click Here​​​​

The RP-502 is an EBW detonator similar to the RP-501 except it can be fabricated with any required lead length up to 100 Ft. The RP-502 has an explosive output equivalent to a # 8 blasting cap.
Note: The wire lead can be up to 100 Ft. in length. Customer to specify length.  ​

​​​SQ-80 EBW Ignitor​

 SAFETY ALERT-​ PLEASE CLICK HERE​

The SQ-80 Ignitor is a thermite filled Exploding Bridgewire ignitor possessing all the safety characteristics of an Exploding Bridgewire Detonator. Threshold firing requirements are the same as for the RP-80 EBW detonator. The SQ-80 is capable of igniting standard propellants and pyrotechnics at distances exceeding 5 inches.

​RP-880​

P/N 188-7354​ - D​ownloa​d as PDF

The RP-880 Fluid Desensitized, RDX, EBW Detonator is purposely designed to misfire when immersed in a fluid and fire properly when fired in air. Misfiring or firing refers to the output portion of the detonator. The RDX provides a higher operating temperature capability as compared with the RP-88 Fluid Desensi-tized, PETN, EBW Detonator.​
