The DCNHR40PF12 is a normally open, single-pole single-throw DC contactor relay with a resin housing for corrosion resistance in harsh automotive environments. It has a 40A continuous current rating, a 12V coil, and 900V DC maximum voltage rating. The main contacts are rated for IP67 ingress protection, and the relay features a pulse width modulation (PWM) coil option for reduced holding power. It is RoHS compliant, meets UL E47258 recognition, and complies with CE standard EN 60947-4-1:2018. The device is surface-mounted with bottom terminals and includes mechanically linked auxiliary contacts. The operating temperature range is -40°C to +85°C.
The DCNHR Series 900V Max High-Voltage DC Contactor Relay is normally open with a low-power coil in a corrosion-resistant housing for use in harsh vehicle environments. The contactor's permanent magnet helps to achieve a high-voltage DC cutoff.This DCNHR Series contactor relay (DCNHR40PF12) is for 40A contact switching and features polarized main contacts and a 12V coil. Designed for 40A contact switching Polarized main contacts 12V coil rating
