| Newly Arrived Test Equipment andElectronic Parts Always check here first!  NEWLY ARRIVED STUFF !  Skip the INTRO, Go RIGHT to the CATALOG! NAVIGATION: To make your life easier, and help you find exactly what you want, we have broken the on-line equipment catalogs into smaller sections. Just CLICK on the item you are looking for at the left, to see the matching catalog. Large graphical catalogs are a bit SLOW, so please give them a bit of time to load. The top header of each catalog is largely the same, so don't think you are stuck in one place!You can order anything here just by picking up the phone, and calling (250) 769-1834 during normal office hours, 8:30AM to 4:30PM PST. OR, Email your order to Susan HERE.
 SHIPPING: Preferred and Alternate Methods as of June 4, 2013, CLICK for FULL DETAILS ON OUR FAQ Page. Rates are now changing rapidy, often with little notice to us, so all the data has been transferred to the FAQ page for speedy updating. E-Mail Susan if you want a quote for shipping to other destinations, or for something heavy. Sorry, we can't safely send most individual small parts in a regular letter envelope, they get destroyed by the automated handling equipment. Sometimes we can ship very rugged parts in a small padded envelope by letter post. Ask Susan.There is a packing charge for large or heavy equipment, see the FAQ for details.If we have your valid data on file, you can just click on the ORDER email link to place an order and indicate your approval to bill, and we will do the rest. We keep your active information for ONE YEAR for your convenience.If this is the first time you have dealt with us, you can phone +1 (250) 769-1834 to supply the billing info, or send it by the email link, as you prefer. We accept VISA/MC, international money order, Paypal (to Susan@Okanagan.net), and bank wire transfer. Please note that there are transaction fees with Paypal and wire transfer payments, the wire transfer fee is frankly horrifying, $50.
 CONDITION: To answer your questions, YES, we completely check and inspect all used equipment, and do not offer any we feel is substandard. That gear is normally scrapped, broken down for parts, or may get offered as-is in the HOT DEALS section, with the unit's condition clearly identified. If there are any marks or detracting features, we clearly state them in the listing. Before shipment, we burn in the equipment for 24 hrs. again and re-check to be sure it is good prior to shipment. The CATALOG will appear below shortly!Don't forget these illustrated sections take a few seconds to load, but they are worth the wait!

Powerful Robotics DC Gearmotors | 2732-0141-2434-16 DC Gear Motors 
   CLICK TO ORDER
|
 Powerful DC gearmotor custom made for Diebold by Igarashi Motor Sales USA, based on the N2732 27mm motor core and a 33mm diameter gearhead (33GN2732 series). Amazingly powerful for such a small motor, the gear ratio provides very high torque. Exact data is not known, but measurements show it seems to a ~9VDC motor at 0.13A (no load, ~100RPM) and runs down to 5VDC (at 0.08A (no load, ~50RPM), and up to 12VDC at 0.28A (no load) with no difficulty. Fully loaded mechanically, the current is roughly double. The drive shaft is a flatted 5mm steel shaft. See full dimensions HERE. They are excellent for all kinds of electromechanical devices, with enough rest friction to allow the motor to act as a brake on the drive shaft. Tapped holes (3 x 3mm) on the gearhead face ends of the motor for attachment. Fully reversible, with all leads floating, it has a 2mm mating connector, and the Tyco pc mounting 2mm connector is INCLUDED. Like all brush DC motors, some L/C filtering is useful to prevent interference with other parts of the circuit. New and unused, ready for your application!

 Click to visit JFW! JFW 50DR-055-SMA 50 ohm/30dB/2W Variable Stepped Attenuators  These new JFW 50 ohm, 2 Watt stepped attenuators are removed from new rack assemblies that were assembled but never used, and include the 4 countersunk front mounting screws and knobs as shown. Rated for 2GHz (but sweep testing showed it is actually flat and accurate to 2.4GHz, with only 0.2dB of additional loss), with stainless SMA connectors. These provide 0-30dB of attenuation in 1dB steps, with typically less than 0.7dB insertion loss at 2.4Ghz. Every unit has been inspected and fully sweep tested for correct operation. If you have ever wanted a wide range RF/microwave variable attenuator for use in your shop, here's a chance to get a beautiful, high quality unit for a bargain price. A perfect addition to an RF/microwave sweeper to give wider level control, or to use for field insertion of loss to test for system integrity. CLICK HERE for full factory PDF data sheet.
Want to convert these to type N connectors? We have new factory sealed Amphenol right angle SMA male to N-female 901-10090 adaptors, add a pair to your attenuator for only $19, they add only 0.2dB insertion loass at 2.4Ghz.

Incredibly Handy Varistors (MOV AC Surge Suppressors)
130/140VAC Varistors Harris 130L20, 130V 20mm Varistor  Siemens S14K140, 140V 14mm Varistor  CLICK for bigger PIC! EPCOS S07K130, 130V 7mm Varistor |
130/140V Varistor (MOV) AC Line Surge Suppressors These handy little devices can be installed in any Test Gear, Stereo, TV etc. after the power switch and fuse on the AC line, and then give excellent protection against line surges, transients and lightning strikes. Varistors (MOVs) dramatically drop in resistance as their break-over voltage is exceeded, and act at high power clippers for incoming signals greater than their steady state rating. We have 3 types, physically smaller blue (7 and 14mm) Siemens S14K140 which clamps above 140Vrms/4500A PK and EPCOS (formerly Siemens) S07K130, which clamps above 130Vrms/1200A PK, and a larger red (20mm) Harris 130L20 (same as V130LA20) that clamps above 130Vrms/6500A PK. The larger disc sizes can dissipate more excess energy. These are what is inside your "protected" power bars, and you can easily add this protection to your equipment (especially to portable items) as well, and prevent all kinds of damage down the road. EPCOS S07K130, $1 each, $450/1K, 5K in stock (RoHS Compliant) LOC: VAR130 / WSS2 Harris 130L20, $3 ea., 800 in stock Siemens S14K140, $2 each, 1500 in stock CLICK HERE to E-Mail us an order!

| DESCRIPTION | |
 Sanyo Denki, CLICK to visit!  CLICK for bigger PIC!  CLICK for bigger PIC! DC FINE ACE 109P0412H601 12VDC Fan +T $19 Ea. NEW100 pcs. |
1.6"/40mm/12VDC FAN +T Sanyo Denki FINE ACE 20 plus alarm assembly 40mm square DC Brushless fan, 12VDC, 0.11A, 20mm inch thick, with Tach output, flying red/black/yellow leads soldered into the PCB. Medium 0.225 cubic meters/min airflow (approx. 8CFM), 5-blade design, 32dBa noise level. UL/CSA/TUV Listed fan. Assembled into a fan/PSU alert module from Bird Products Corp., Assembly 50660, Rev. G. This can be run from 24 to 11VDC (or even less, but fan speed suffers). The fan is fixed at 12V or less (via the regulator), and has an integral fault alarm if it becomes stalled, which sounds a loud acoustic transducer. A very handy assembly, this has input power leads with TYCO FASTON double connectors that allows a second connection to each lead. Very well made, and easily disassembled if the alarm is used separately from this fan, as it should work with almost any 12V fan that has a tach output. This assembly would be perfect to ventilate and cool a constantly charging 12V battery pack in a UPS or similar system. Each one is indivudually bagged and sealed in an anti-static bag for protection.
