  • Aircraft Escape Systems

    Teledyne Defense Electronics

    The Emergency Interseat Sequencing System (EISS) was designed an qualified for the F-15K Fighter and has since been installed in the F-15SG and F-15SA configurations of the F-15. The system consists of Thermal Batteries with Initiators, a Digital Interseat Sequencer, Mode Selector, and customer provided cabling Electro-Explosive Devices (EEDs). The system is operated from either thermal battery and aircraft 28Vdc for redundancy. A separate field Test Set (EESSTS) performs both complete system continuity tests and an operational test of the total system installed in the aircraft. The sequencer is programmable and could be used in any escape system.Based on the initiation point, Forward or Aft Seat Handle, Internal or External Canopy Jettison Handles, and the Mode Selector setting, the Sequencer provides firing pulses to the EEDs to support canopy removal, ejection seat inertial reel activation(s) and ejection seat catapult firing(s). Sensing capabilities are provided to determine system state, canopy gone, seat gone, so as to provide the optimum escape timing.

  • MAX31855 T-Type Thermocouple Arduino Shield

    SEN-30004-T03 - Playing With Fusion Inc

    Four channel MAX31855 digital thermocouple Arduino Shield. Two versions of this shield are avaliable for each thermocouple type: either 'Ch 0-3' (CS pins use Uno/Mega IO pins 7-10) or 'Ch 4-7' (CS pins use Uno/Mega IO pins 3-6), with the only difference being which set of zero-ohm resistors are populated on the board. This allows use of other SPI devices that may be 'hard coded' to specific digital pins on the Arduino, or simply stacking one of each type together to get a total of eight thermocouple channels on one Arduino.Each order comes with one board and a set of four female, long extension, headers that can be soldered to the board. If stacking two of these modules on top of each other, please order both a Ch 0-3 and a Ch 4-7 board, as well as an additional set of headers for stacking. We're working on sourcing even longer headers, but the ones currently available are not long enough to stack as-is (they need to be double-stacked).The MAX31855T supports a measured temperature range of -270C-400C with known thermal characteristics and output resolution of 0.25C. Included thermocouple connectors are type-specific to provide proper material continuity as close to the IC as possible. The SEN-30004 is interfaced via 3 or 4-wire SPI and a high-speed level shifter is included to allow the board to plug directly into an Arduino Uno or MegaNote: we also offer a universal version of this board in a smaller for factor, the SEN-30003-T.FeaturesType-specific, miniature-sized vertical thermocouple connectors (vertical flat blades, see pics)Measures four (4) thermocouple channels, full extended range.Boards are stackable.

  • Electrical Safety Test Equipment

    IBEKO Power AB

    Making a product “safe” requires an understanding of “hazards” that exist in each electrical product. Electrical shock is one of the four fundamental hazards. Because of that, it must be a part of any product electrical safety evaluation. Even though a product requires an electrical power source and uses electrical or electronic components, it should not present an electrical shock hazard to the user.Ground bond or earth continuity testing prevents electrical shock hazards. Similarly to a fault to earth, test instruments generate a high current. The standard requires that the resistance between protective earth and any conductive surface on the equipment does not exceed 0,1 Ohm. The test is performed by applying a DC current between the conductive surface and protective earth. By measuring the voltage drop, it calculates the resistance.RMO-E instruments are ideal for testing the protective bonding (grounding) of equipment following the standard IEC 61010-1. Applying current up to the value of 100 A and the ability to provide in the Contin menu (continuous operation) test current for the pre-set test duration (equal or exceeding 1 min) gives a user a possibility to easily check the protective bonding/grounding of the equipment. The full load voltage of 12 V assures proper measurement and accurate result. Finally, an instrument displays pass/fail classification according to user-preset parameters.

  • USB Type-C Test Fixture | CB26U | Cable Harness Tester

    CAMI Research Inc. (CableEye®)

    A USB Type-C test interface board for CableEye® cable and harness testing systems. Consisting of a daughter board, populated with two USB-C female connectors, it allows users to continuity-check USB Type-C terminated cables using the CableEye tester while seeing the connectors-under-test rendered graphically. The CB26U fits all CableEye models. Configuration A leader in development of PC-based cable and wire harness, continuity, resistance and hipot test systems for over 20 years, CAMI offers the CableEye suite of products complete with accessories – including “connector boards”. The selection of these test fixture boards is constantly growing and is currently numbering over 60 – most of which are populated with ‘families’ of connectors. When pre-populated boards are used, the tester GUI automatically displays a graphic of the connectors under test. Sold as a set of two boards, each CB26U accepts two USB Type-C connectors. In addition to the latest CableEye software, it requires the CB26 small-frame motherboard (Item 756) for operation, and plugs into one of two available slots – two USB-C-connectors can be tested simultaneously. The CB26 (with CB26U) attaches to the tester like a regular connector board. Contact sales@camiresearch.com or +1 (978) 266-2655 for a quote.
