M1003 Stopswitch: Elevator & Conveyor Stop Sensor with Instant Response

Looking for a reliable elevator stop sensor? The M1003 Stopswitch from 4B Braime Components (UK) is a compact inductive sensor that instantly detects complete shaft, bucket, or belt stoppage. Upon no rotation (belt slip, breakage, jamming), it triggers an emergency shutdown signal. Perfect for grain elevators, feed mills, flour mills, and port terminals.

Advantages of M1003 Stopswitch

Why choose the M1003 4B stop sensor?

• Instant response: Detects stop in 0.3 seconds.

• Contactless inductive operation: No wear, 10+ year lifespan.

• Dust & moisture resistant: IP67 housing, ATEX Zone 20/21, -40°C to +80°C.

• Easy installation: Mounts 10–15 mm from rotating metal part, no markers needed.

• Universal output: SPDT relay, 250 V / 5 A — connects to SCADA, PLC.

How M1003 Stopswitch Works

The sensor is positioned 10–15 mm from a rotating metal part (shaft, bucket bolt, pulley). During normal operation, metal pulses keep the relay closed. If rotation stops (belt break, jam), pulses cease — relay opens, triggering:

• Emergency elevator stop

• Signal to controller or alarm

• Material feed block

This prevents:

• Bucket fall into shaft

• Bearing overheating

• Friction-induced fire

• Feed mills

• Flour milling complexes

• Ports and bulk terminals

• Automated warehouses

Installation on Elevator

Mounted opposite bucket bolt on bottom or top shaft. Belt break — stop in 0.3 sec. System blocks loading, preventing overflow.

Use on Conveyor

On belt conveyor, monitors roller movement. Belt stop (jam, break) — instant line shutdown.
