Test Probe Specification

Installation

The non-replaceable micro test probes feature a collar at the top of the barrel, which is used as a stop in the fitment process. Due to the minute barrel diameters and thin walls, it is imperative that the drilled hole diameter (0.27mm - 0.28mm) and straightness are very accurate. We recommend that the pre-wired option is taken as connecting a cable to these probes is an extremely delicate operation.

Usually, multi-plate fixtures containing no less than 3 plates are used to retain large multiples of probes.

Otherwise a block of stable material which will allow reliable drilled holes is to be recommended, with the micro test probe fitted wire/tail first with tweezers, with a small amount of locking compound on the side to secure it, if required.

Installation

The non-replaceable microprobes feature a collar at the top of the barrel, which is used as a stop in the fitment process. Due to the minute barrel diameters and thin walls, it is imperative that the drilled hole diameter (0.34mm - 0.36mm) and straightness are very accurate. We recommend that the pre-wired option is taken as connecting a cable to these probes is an extremely delicate operation.

Installation

The receptacles of the replaceable micro test probes feature a collar at the top of the tube, which is used as a stop in the fitment process. Due to the minute tube diameters and thin walls, it is imperative that the drilled hole diameter and straightness are very accurate. It is recommended that the pre-wired option is taken - as connecting a cable to these receptacles is an extremely delicate operation.

Usually, multi-plate fixtures containing no less than 3 plates, are used to retain multiples of receptacles.

Otherwise, a block of stable material which will allow reliable drilled holes is to be recommended, with the receptacle fitted wire/tail first with tweezers. A small amount of locking compound may be required on the barrel to secure it. Then the microprobe may be pushed into the receptacle, tail first, using the tweezers, making sure light pressure is put onto the probe's collar, not onto the fragile plunger.

Installation

The tail of this micro test probe plugs into a socket installed in a second block which is located beneath the probe plate. This allows the probe to be a replaceable item, without the extra width of a receptacle around it. The socket can either have a cable crimped or soldered to it. It can also accept the RM4T terminal plug.

INSTALLATION

The top of the PAO barrel is flared making its design different to many probes. This allows a high density of probes to be "pressed" directly into the probe plate eliminating the need for a receptacle or gluing. This "press-fit" feature also permits it to be installed in a variety of probe plate thicknesses and can be replaced relatively easily. The PAO is available with or without 30" of 30 AWG insulated wire attached. It is installed into the probe plate with a probe insertion tool (part no. PITO) or a pair of tweezers. Shrink tubing can be used on alternate probes to provide strain relief in the termination and to reduce the possibility of electrical shorting.

To replace the probe, the wire is cut at the termination and the probe is then pushed out of the probe plate.
