Ring terminal Erko KCS90 10 x 150 mm, copper, 90° angled tubular eye

Erko KCS90 10 x 150 mm is a copper ring terminal with a 90° angled tubular eye designed for secure electrical and grounding connections. The connector combines a crimpable tubular barrel for conductor insertion with a flat ring face for bolted attachment, providing a low-resistance copper path and a compact angled termination. With a nominal bore of 10 mm and an overall length of 150 mm, this ring terminal is engineered to fit medium to large conductors in installations that require an offset or right-angle connection.

Advantages

The 90° angled design reduces profile height at the connection point and allows for neat routing of cables in tight spaces. Copper construction ensures good electrical conductivity and corrosion resistance when used with appropriate surface treatments or compatible fasteners. The tubular barrel provides a reliable crimp zone for mechanical and electrical continuity, while the flat ring enables secure bolted joints with uniform pressure distribution.

Suitable for (tasks / use cases)

• Grounding and earth connections in electrical panels and switchgear
• Battery and power distribution terminations in automotive and marine systems
• Industrial machinery where angled cable exit is required
• Retrofit or repair work that needs low-profile bolted connections

Key specifications

• Material: copper
• Shape: ring terminal with 90° angled tubular eye
• Nominal bore (ring inner diameter): 10 mm
• Overall length: 150 mm
• Connection type: crimp tubular barrel for conductor insertion and flat ring for bolted joint
• Suitable conductor types: stranded and solid copper conductors (appropriate conductor size to match barrel diameter)

How to use

Strip the insulation from the conductor to the appropriate length for the tubular barrel, insert the conductor fully into the barrel, and perform a crimp using a suitable crimping tool sized for the terminal and conductor. Position the ring over the mating stud or bolt and fasten with a compatible nut and washer to achieve a tight, low-resistance connection. Ensure correct torque is applied for the bolt size used and verify mechanical stability and continuity after installation.

Usage recommendations

For reliable performance, use corrosion-inhibiting compounds or compatible plated fasteners in corrosive environments, and select the correct crimping die and torque setting for the conductor cross-section. Inspect connections periodically for tightness and signs of corrosion or overheating.
