Product details

The Omron E3JK-5M1-N is a through-beam photoelectric sensor in a block-style housing. It uses an infrared LED light source at 950 nm and a separate receiver to detect an opaque object of at least 14.8 mm diameter breaking the beam at up to 5 m. The output is a relay rated for 0 to 3 A load current, so it can switch small motor contactors, solenoid valves, or indicator lamps directly without an interposing relay.

Deployment context

This sensor is a block-style unit — it bolts to a bracket or machine frame, not a DIN rail. The through-beam pair (emitter and receiver) needs clear line-of-sight across a gap up to 5 m. The relay output means it can handle the inrush of a small motor starter or a panel indicator without a separate solid-state interface.

Frequently asked questions

What is the output type on the E3JK-5M1-N?

It has a relay output rated for 0 to 3 A load current. That means it can switch AC or DC loads up to 3 A directly, which is useful for driving contactors, solenoids, or alarm circuits without an extra relay.

What is the sensing distance and minimum object size?

The through-beam pair detects an opaque object of at least 14.8 mm diameter at distances from 0 to 5 m. The infrared LED (950 nm) is immune to ambient light interference in most indoor industrial settings.

How does the E3JK-5M1-N compare to the E3ZM-T61 2M?

The E3ZM-T61 2M is a newer, compact stainless-steel sensor with a 15 m range, NPN output, and IP67/IP69K rating. It runs on 10-30 VDC and has a 100 mA load limit. The E3JK-5M1-N has a relay output (0-3 A), a 5 m range, and uses an infrared LED — it is larger, less sealed, but can switch higher loads directly. They are not drop-in replacements; the mounting, wiring, and power supply differ.
