Plastic connector for a high current applications EM52M/40M/30M Series Features 1. The robust lightweight, high current design is enabled by using high-quality plastic material which is resistant to rough handling. 2. Quick and secure push-on bayonet lock The push-on bayonet locking mechanism enables complete locking in one quick mating action. 3. Multi-surface contact spring design High-current is achieved by using the multi-surface contact spring design. 4. Standard crimp tool for easy crimp connection Contacts can be crimped by using a JIS Standard- meeting crimp tool (JIS C 9711). 5. Available in a water-proof version It is available with water-proofness by using a cable gland (Note 1). 6. Finger protection design Complies with the electric shock proof specification (IP2X). (Note 2) 7. TV, UL EM40, EM30 UL registered. (Note 3) EM52M : TV registered : UL application pending 8. Meets RoHS standards Note 1 : Keigland, manufactured by SANKEI MANUFACTURING Co., Ltd. Note 2 : Applies only to plug side in the case of EM40M and 30M. Note 3 : EM40M and 30M are only applying for UL. Please con rm speci cations at time of delivery.
