General Purpose Test Probes > Long Reach
- Recessed test targets
- Component leads whose height may vary
- Replaceable test probe by use of a receptacle
- Dual-height test fixtures
ELPA2 Series
Designed for use in dual-level fixturing where two different sets of probes with different working travels are required in the same test fixture. The long reach of this item also enables access to contacts which are otherwise inaccessible with normal length probes.

LPA4 Series
Designed for use in dual-level fixturing where two different sets of probes with different working travels are required in the same test fixture. The long reach solves other problems of gaining access to contacts which are inaccessible with normal length probes. Use the standard RA4 series receptacles as shown in the ELPA4 Series.

ELPA4 Series
The ELPA4 series has an extra-long full travel of .492" (12.5mm) compared with the .410" (10.4mm) of the LPA4 series, and with .250"(6.35mm) of the standard PA4 series ATE probes. They will fit the standard RA4 series receptacles. Additionally the ELPA4 series probes has spring force of 8.8oz (250gm) which will help in penetrating contaminates on unclean test points.
