Simple Assembly In-Line
Power Connectors for up to 160A
Dec. 2020 ⑥
EF1 Series/Simple Assembly In-Line Power Connectors for up to 160A
Features
1. Connection by simply
inserting the ring terminal
into the case
Dec.1.2022 Copyright 2022 HIROSE ELECTRIC CO., LTD. All Rights Reserved.
Connection is completed with only a few labor
steps by simply crimping the contact to the power
cable and inserting to the housing.
2. Quick snap- in lock, no screw
retightening
The snap- in mating design reduces the number of
cable routing steps. Since the connector does not
use screws, there is no risk of loosening.
3. Rated Current of 160A when
using 38mm2 cable
The conductor diameter of 5. 5, 8, 14 and 22mm2
cables can be converted to 38mm2 by using a
sleeve.
4. Choice of two mounting
options: DIN rail attachment
or panel
This connector is versatile enough to be used in
a wide range of mounting applications.
5. Simplified crimp termination
No special tools are required.
6. Equipped with guide keys
Guide keys are used to prevent incorrect wiring.
7. TÜ V, UL certified
8. RoHS compliant

The rated current value varies depending on the ambient temperature in which the connector is used. It is recommended to use the product
within the derating curve zone (dashed lines).
When using a UL or TÜV approved product, please use the product within the specified range as well as the derating curve area.
Includes the temperature rise due to current flow.
