Product Overview

The Omron E2B-M12KS04-WZ-B1 2M is an M12 shielded inductive proximity sensor from the E2B family, manufactured by Omron Corporation. Hengyixin Automation ships this sensor from our Xiamen warehouse with a 30-day DOA return window and a datasheet PDF included in the box.

The sensor detects ferrous metal at 4 mm with a quasi-flush shielded mounting. It runs from 10 to 30 VDC (12 to 24 VDC nominal), draws 10 mA or less, and outputs PNP open-collector up to 200 mA. Response frequency is 800 Hz and the action is NO - the output turns ON when the target approaches. A yellow operation LED sits on the housing.

The housing is nickel-plated brass with a PBT sensing face and a 2 m PVC pre-wired cable. IP67 protection and -25 to 70 C operating range cover typical washdown and shop-floor conditions. Built-in protections cover output reverse polarity, supply reverse polarity, surge suppressor, and short circuit. The E2B-M12KS04-WZ-C1 2M is the NPN sibling.

Key Features

  • M12 shielded short-body inductive proximity sensor, 4 mm sensing distance, quasi-flush mounting
  • PNP open-collector NO output, 200 mA load, 800 Hz response, yellow operation LED
  • 10 to 30 VDC supply (12-24 VDC nominal), 10 mA max current consumption, surge / short-circuit / reverse-polarity protection
  • IP67 housing, nickel-plated brass + PBT sensing face, pre-wired 2 m PVC cable, -25 to +70 C operating
  • SKU: E2B-M12KS04-WZ-B1 2M
  • Series: Omron E2B M12 inductive proximity family
  • Voltage: 10 TO 30 VDC

Best-Fit Applications

  • End-of-stroke check on a packaging slide where the 4 mm shielded M12 fits a tight boss and the PNP output drives a CP1L DC input
  • Presence detection on a small parts feeder where the yellow LED confirms trigger state at commissioning and the 800 Hz catches each cycle
  • Cylinder-home check on a pneumatic pick-and-place where the 12-24 VDC sensor plugs into a standard input and the IP67 body tolerates oil mist

Buying Checklist

  • Pick the E2B-M12KS04-WZ-B1 2M for an M12 shielded 4 mm PNP NO inductive sensor with a 2 m pre-wired cable.
  • Pick the E2B-M12KS04-WZ-C1 2M instead when the cabinet needs NPN output instead of PNP.
  • Pick the E2B-M12KS04-M1-B1 2M instead when the sensor needs an M12 4-pin connector instead of a pre-wired pigtail.

FAQ for E2B-M12KS04-WZ-B1 2M

What is the E2B-M12KS04-WZ-B1 2M output type?
PNP open collector, normally open. The B in E2B-M12KS04-WZ-B1 2M is PNP; the C variant is NPN. The 1 in B1 is normally open; B2 is normally closed.
What is the sensing distance of the E2B-M12KS04-WZ-B1 2M?
4 mm on mild steel (12 x 12 x 1 mm reference target) with a +/- 10% tolerance. Set the operating distance to 0 to 3.2 mm for reliable operation across the production tolerance band.
Does the E2B-M12KS04-WZ-B1 2M work with a CP1L DC input?
Yes. The PNP output sources 24 VDC into a CP1L DC input card configured for sinking inputs. For NPN outputs driving the same card, pick the E2B-M12KS04-WZ-C1 2M.
What cable does the E2B-M12KS04-WZ-B1 2M ship with?
A 2 m PVC pre-wired standard cable with 4 mm outer diameter. The 5 m version has the suffix 5M; the M12 4-pin connector version has the suffix -M1.
Is the E2B-M12KS04-WZ-B1 2M IP67 rated?
Yes. The housing is rated IP67 per IEC 60529 and EMC EN 60947-5-2. Operating range is -25 to +70 C and humidity 35 to 95%.
