HAKKO FG 470 wrist strap tester from japan

 

 

The HAKKO FG-470 wrist strap tester is a device from Japan for testing the reliability of anti-static wrist straps by measuring the contact resistance between the strap and the user's skin. It uses a highly visible LED and buzzer to indicate a "PASS" result and has a mounting holder for easy, one-handed use on a wall or desk. The device is powered by a 9V battery and can also be used portable off its holder. 

  Features and functionality Functionality: Checks the grounding wire contact resistance between the wrist strap and the operator's skin to prevent damage from static electricity.User feedback: Provides an easy pass/fail judgment via a high-visibility LED light and a buzzer sound for the "PASS" result. 

The buzzer will not sound if the test fails.

Design: Features a user-friendly, one-handed operation pad and a banana jack for easy plugging and unplugging.

Portability and mounting: Comes with a dedicated mounting holder that can be attached to a wall or desk with screws. The main unit can be removed from the holder for portable use.Power: 

Uses a 9V battery and includes an automatic shutdown function to extend battery life. 

  Specifications:

Dimensions: Approximately (85 x 44x 90) mm (without holder). Weight: 120g without battery, 160g with holder and without battery.

NOTES:

1. Instructions: 

Quick and secure test on the function of wrist strap as being worn

User-friendly design

• A user-friendly pad secures pass/fail judgement on a wrist strap.
• A banana jack on the front panel makes it easy to plug and unplug a wrist strap.

• 

• 

Indication of test result by LED and buzzer

Highly visible LED lamps and buzzer will indicate test result.

• Buzzer sounds only for "PASS".

Dedicated holder included

A mounting holder can make it easy to plug and unplug even with one hand. No tool is required to remove a unit.
A unit can be portable off the holder.

* example of installation

Connection patterns

There are several connection patterns to choose depending on wrist straps.

Works as a combo tester

FG-470 can work as a combo tester with FG-465, a footwear tester, that makes it possible to conduct measurement, evaluation and recording of both footwear and wrist strap at once.

• Connecting cable (B5264) or Unit integration base (B5263), sold separately, is required.

ESD Tweezers HOZAN P-640-S from Japan

ESD Tweezers HOZAN P-640-S 

HOZAN ESD Chip Tweezers are made of anti-static engineering plastic for electrostatic protection. The body is made of durable stainless steel. The HOZAN ESD Chip Tweezers are made in Japan and are designed to have a low grounding resistance of Rg<1×10^12Ω. This ensures efficient dissipation of static electricity, making them ideal for use in electrostatic-sensitive environments. The tweezers are suitable for various applications, including electronics repair, jewelry making, and model building. About Tweezers ESD control value: 1×104≦Rg<1×1012Ω Material: Body (Stainless steel /SUS420J2), Tip (PEEK)*1 Heat resistance temperature: 315°C (tip) *2 Tip color: Black Weight: 17g Total length: 125mm Tip width: P-640-S(1.2mm), P-641-S(0.4mm /Tapered), P-644-S(0.6mm /Tapered), P-642-S(1.0mm /Curved), P-643-S(2.4mm /R Tip), P-645-S(6.0mm /Spatula Tip) About Replacement Tips P-640S-1: For P-640-S Tip P-641S-1: For P-641-S Tip P-644S-1: For P-644-S Tip P-642S-1: For P-642-S Tip P-643S-1: For P-643-S Tip P-645S-1: For P-645-S Tip *1 PEEK (polyetheretherketone): Super engineering plastic with excellent mechanical strength, heat resistance, abrasion resistance, and chemical resistance. *2 Heat resistance in soldering operations has been confirmed by our company. We recommend that customers test heat resistance in other applications.

   

 

For P-640 to 650 series

*¹ PEEK (polyether ether ketone) is an engineering plastic that has particularly good mechanical properties and heat resistance.

*² PBT（poly butylene terephthalate）is an engineering plastic that has particularly good mechanical properties and heat resistance.

*³ HDPE：High Density Polyethylene.
