Okay, they’re just strips of metal, but CJ says one of each and a grapefruit will get you at least a “C” at the science fair. The copper electrode is 100mm long x 18mm wide x .8mm thick (3.94" x .7" x .041”). The zinc electrode is 4” long x 3/4” wide x .027” thick and stamped “ZN”. And both of them are awfully useful for crafters and jewelry makers, too.
Our VP for Sensing Fluid Pressure called this sensor from Kavlico “sweet.” Needs a 5VDC 20mW power source, and will likely put out 0-4VDC, contingent on pressure, from 0-5"/H2O max, we’d say. Measures 1-5/16" x 17/32" on a pair of 7/8" long 5/32" slotted mounting wings. The upper 3/16" OD barb is the low side, and the lower is (ironically) high. Has a 3-pin connector with legend on the back for power and output. Call for a data sheet.
Rated for 10A at 250VAC, these normally closed thermal fuses will pop at 128ºC or 262ºF. The fuses themselves are 1/2" long but yours will be wired into leads of assorted lengths, because they were betooken out of coffeemakers of some sort. Never been popped, though, because then they would be useless and who'd buy 'em?
With this 1.2K OHM 10% tolerance power resistor. Rated 3 to 5 watts, it has a ceramic block body 3/8" sq x 1-1/2" long with wire leads on ends, one of which is 1/2" long and the other 1-1/2". Any questions?
These black aluminum alloy heat sinks have flared fins at 1-3/8" x 1-1/2" x 1/2" with (2) pins out one short side and (3) 1/8" mounting holes in the center. Wethinks these are PCB mounts for TO series chips.
Our black anodized channel-style heat sink measures 1-1/4" x 1-1/2" x 7/16" with folded back fins and a pair of 1/8" mounting holes in the flat center. Come on, you've got some heat to sink. Who doesn't?
Perfect for hands-on hobbyists. Foot-pedal speed controls free up your paws to do the real work. This one's for 120VAC devices, and ideal for machines using approx 200W or less. Measures 5" x 3" x 2-1/4" tall, with a 6-foot cord that plugs into the wall and a grounded female plug for your sewing machine, rotary tool, scroll saw, or, if you really make a lot of banana Daiquiris, blender.
When parking becomes so expensive that meters take an ATM card instead of a quarter, all those coin-operated meters become surplus! Now you can own the mechanism from a used POM Inc. digital meter. Measures 7" tall x 5" wide x 3-7/16" thick, with a 1-13/16" x 11/16" LCD display window on the front and a motorized 3-color window on the back. Coin-box and mount not included. Requires a 9V battery (also not included) and has a reset to the left of the coin-slot. Preset for (12) minutes per quarter and if you can find a way to change it, let us know. Perfect for charging folks to park in your driveway, and just screaming to be included in a steampunk creation.
This chassis-mounted in-line EMI filter from Schaffner (model #FN2020-3-06) accepts up to 3A at 110/250VAC. Unit measures 1-3/4" x 1-5/16" x 1-3/16" with (2) 3/16" mounting holes on side wings. Has 1/4" quick-disconnect terminals and has a wiring diagram on the housing. UL/CSA.
From Honeywell (part #AWM730B5), this medical airflow sensor is a takeout with a range from -300 to +300 SI/min. With a 5V activating current, will give an output between 0.5 and 4.5V responding in <10ms. Pins 1-4 are +15VDC in, ground, 5V in, and output. Unit measures 1-7/8" long x 13/16" dia, mounted on a 1-1/8" x 1-3/4" bracket. We'll include a spec sheet. Made in the USA.
This 4" x 3-3/4" x 1-3/4" medical take-out air sensor has (3) ports coming off the main 3-1/8" x 3/4" ID chamber, (2) leading to one sensor and the other leading to a second one, then through circuitry on a mounted PC board leading to a 10-pin output connector. Also has a PCB-mounted 3V coin cell battery. The sensors have input, output and trigger voltage and a voltage output, but we have no specs. Nice parts and pieces, though.
This remote VGA receiver measures 3-1/4" x 3-1/2" x 1-3/16" and is made to use with the NTI CAT5 VGA remote system which allows VGA and sound info to be transferred up to 600 feet on a CAT5 cable. Don't have the system? Pop the rivets on the bottom and you've got a dandy project case, a PCB-mount 5.5mm barrel plug and 1/8" audio jack plus whatever you can strip from the PCB board.
Made to be used on the suction side of a vibratory pump, this flow sensor prevents measuring errors during water-flow pulses. Unit measures 2" dia (3" long with connectors) x 1-9/16". Uses 4.5-24VDC @ 5-13mA. Tubing connects via 1/4" OD hose nipples. Does not supply an output voltage but switches the signal terminal from ground to open. We'll throw in a data sheet for you, too. Digmesa part #974-9501.
Our inline filter helps rid your AC line of EMI and spikes. Rated for up to 16A at 250VAC. Has quick-disconnect terminals for the line and lead sides. Schematic is on the 1-1/2" x 1-3/8" x 1-5/8" housing.
These high-end valve assemblies are medical take-outs from Lee Industries, but that’s all we know except that they look really expensive and fancy and high-quality, and are probably worth much more than we’re selling them for. Each has a 3VDC 275mA 2-phase stepper motor into a 5-250uL valve housing with a 5-pin connector that hooks up to (3) Omron infrared-based photomicro sensors. There’s what looks like a 4-pin encoder on top, as well as a 1/16” barb. Lee part # LPVX0520750CA.
Wethinks this is some sort of pneumatic punch assembly. The cast aluminum body is a 3-3/4" x 2-3/4" x 1-3/4" block with a 1/4" dia spring-loaded punch, (2) rows of (6) 12VDC 500mA, 15psid solenoids sealed into the block with a printed circuit board, wiring harness and a 3/32” inlet barb. Whole shebang measures 4-3/8" x 3-3/4" x 3". Part# LHDX0512700BA.
For you reverse engineers, this 48 LED x 12 LED matrix board from Saco® has TLC5941 LED driver ICs, VHCT541 line drivers, and a PTH05060 power regulator. Has (2) 8-pin connectors for power marked with “ground” or (+). This is a sweet LED board. Some experience required. Supply voltage should be 3VDC. We think the LEDs are RGB, but there endeth our insights. Measures 17-1/2" x 4-3/8" with easily accessible data connectors.
