New Battery Probe from Everett Charles Technologies:

Performance Off-the-Shelf with the New ECT CP-4 Probe

Everett Charles Technologies (ECT) recently expanded its portfolio of Battery Interconnect Probes by adding the CP-4 probe. CP-4 is a standard off-the-shelf solution, which has been designed specifically for rigorous high reliability applications. CP-4 combines the low technical risk, fast delivery and high economies of scale of a typical standard product with the extraordinary electrical performance and reliability resulting from ECT’s extensive spring probe knowledge of materials and platings.

The CP-4 meets the requirements of high reliability applications by ensuring sustainable, consistent, and reliable contact. It is also tolerant to shock and vibration. The relatively high compliance helps to overcome planarity issues.  The CP-4 probe is capable of carrying 10 Amp DC and provides a low resistance contact (25 mOhm average). It has a proven life of over 100,000 cycles.

The outstanding performance is based on ECT’s proven Biasing-Ball™ and double roll close construction. The design using a deep draw plunger for a low mass head increases reliability in shock/vibe.

The CP-4 probe can easily be pressed into plastics or attached to a PCB. The CP-4 tail configurations include surface mount, through hole (straight or 90 degree angle) and solder cup. It is available as a lose probe or integrated into a custom Compliant Connector Solutions, CCSâ„¢. (To read more about the CP-4 or CCS see our website

Tony DeRosa, Product Manager, highlights: “CP-4 provides reliable high performance at lower cost than other similar in-class products. Leveraging ECT’s design expertise and complete manufacturing capabilities, the CP-4 is a cost-efficient solution that will help to bring products to market faster and easier.”
