Why Choose the ILME CKSF03 Female Insert?
The ILME CKSF03 is a compact and reliable female industrial connector insert designed for detachable electrical connections in machinery, automation and control equipment. Part of the ILME CKS series, this size 21.21 insert provides 3 poles plus protective earth (3P+PE) and uses spring terminal technology for fast, secure conductor termination.
Rated at 10 A and 400 V, the CKSF03 provides dependable electrical performance for industrial power and control circuits. Its turned silver-plated copper-alloy contacts offer reliable conductivity, while the polycarbonate insulating body provides robust electrical insulation and achieves a UL 94 V-0 flammability rating.
The spring terminals accommodate conductors from 0.14–2.50 mm² (AWG 26–14) with a recommended stripping length of 9–11 mm. With a rated impulse withstand voltage of 4 kV, pollution degree 3 and an operating temperature range of -40 °C to +125 °C, the CKSF03 is well suited to compact industrial connector assemblies requiring reliable and efficient field wiring.
