Product Overview

Introducing the CT4537 Series Probe Bodies from Cal Test Electronics — available in two tip configurations to support a wide range of probing and connection needs. Choose between a precision 2 mm tip (CT4537-01) for fine-point contact on dense circuitry and for accessing North American power sockets, or a 4 mm banana plug tip (CT4537-02) for direct insertion into banana jacks or for attaching accessories. Designed in accordance with IEC 61010-031, these probe bodies provide 1,500 VDC CAT III / 1,000 V CAT IV protection with the safety cap installed, making them suitable for industrial, field service, and laboratory environments.

 

Each probe body features a brass, nickel-plated tip engineered for reliable, consistent contact. A removable safety cap ensures proper protection during standard probing tasks and exposes the tip when direct connection or fine probing is required. Both versions accept any standard 4 mm sheathed (safety) banana plug test lead, ensuring broad compatibility across test setups.
