From RS Pro, a range of original line hand crimp tools designed to crimp uninsulated open barrel connectors. The precision hand crimp tools feature a ratchet action mechanism ensuring full crimp cycle is achieved with each use. Tools also benefit from a safety ratchet release in case of incorrect operation. With ergonomic handles and a durability of a minimum 50000 cycles, the tools are both robust and comfortable to use. Producing B/F crimps, with the minimum of effort, either right or left handed. All models are highly reliable and excellent quality.

• Non-slip main handle and low friction moving handle ensue a comfortable hand grip
• Provides two-hand grip in the final phase of crimping, increasing comfort and productivity
• Full cycle crimp mechanism to ensure consistent, reliable crimp
• Ratchet release mechanism to clear mis-crimps and obstructions
• Precision eccentric adjustment for consistent performance and ability to calibrate
• Each tool has a unique serial number for traceability
• Durable: life span exceeds 50000 cycles
• High strength, through hardened alloy Swedish steel construction

Part number 683-1620 for crimping in the range of 0.1 mm² to 1.5 mm²
Part number 683-1611 for crimping in the range of 0.5 mm² to 6.0 mm²

Typical Applications
Crimping tools can be used for a variety of applications:-
• Maintenance & repair
• Electrical Installations
• Cable assemblies

How to maintain the product?
• To maintain a good function and long life: Axles and other movable parts should be regularly lubricated
• Lubrication* is recommended at least every 10,000 cycles whenever tool is exposed to dirt or other contaminants
• Adjustment of the crimping die nests should also be checked. Readjustment of the pressure adjustment axle is necessary when the pre-load of the tool decreases significantly

*Use a light mineral-free oil

The Importance of a High-Quality Crimp
When a crimping tool is used on a terminal, two crimps take place at the same time. One is the electrical connection between the conductor and terminal. The other is the insulation crimp which provides strain relief against vibration and tension. It is important that the electrical connection is gas tight without any voids between the wire strands and the terminal. If there any voids present, then corrosion can occur causing resistance and excessive heat which damages the electrical connection. Using a good quality crimping tool will ensure that a full, gas tight crimp is produced preventing future deterioration of the electrical connection and insulation breakage.
