What type of device is this?

This is an inductive proximity sensor designed to detect metal objects without physical contact. It is suited to industrial sensing tasks where reliable, non-contact detection is needed.

What is the sensing range?

The rated operating distance is 8 mm. The assured operating distance is 0 to 6.48 mm, giving a dependable detection zone within the specified installation conditions.

Is it designed for flush or non-flush mounting?

This model is intended for non-flush installation. It should be mounted with suitable clearance around the sensing face so it can achieve the stated sensing performance.

What output arrangement does it use?

It uses a 2-wire AC output with a normally closed switching function. In practical terms, the output state changes when a metal target is detected within range.

What operating voltage does it support?

The sensor operates from 20 to 253 V AC. For applications below 0°C, the permissible operating voltage is 80 to 253 V.

What current range is suitable for operation?

The operating current range is 5 to 200 mA. The off-state current is typically up to 1.7 mA, and the momentary current can reach up to 1600 mA for 20 ms at 0.1 Hz.

How fast can it switch?

The switching frequency is up to 20 Hz. This makes it suitable for applications where detection speed is moderate rather than high-speed counting.

Does it include status indication?

Yes. It features a green LED for operating voltage indication and a yellow LED for switching state indication, which helps with installation checks and visual monitoring.

What are the housing size and materials?

It has an M18 cylindrical housing with a diameter of 18 mm and a length of 60 mm. The housing is brass with nickel plating, and the sensing face is made from PBT.

How is it connected?

This version is supplied with a 2 m PVC cable. The conductor cross-section is 0.34 mm².

Is it suitable for demanding environments?

It has an IP67 protection rating, which means it is built to withstand dusty environments and temporary immersion in water under defined conditions. This makes it a practical choice for many industrial installations.

What temperature range can it operate in?

The ambient operating temperature range is -25°C to +70°C, allowing use across a broad range of industrial conditions.

Does it have reverse polarity protection?

Yes. The sensor is reverse polarity tolerant, which adds resilience during installation and wiring.

Are there any installation considerations for metal targets?

Yes. As with other inductive sensors, sensing performance varies by target material. Reduction factors are 0.4 for aluminium, 0.4 for copper and 0.7 for stainless steel 304, so actual sensing distance may be lower than with a standard steel target.

Is any fuse protection recommended?

A quick-blow fuse of 0.8 A or less is recommended in line with IEC 60127-2 Sheet 1. For the 124315 version, it is also recommended to check correct function after a short circuit.
