Technical Overview

The Festo SMH-S1-HGW10 (Part Number: 175711) is a specialized magnetic Hall position sensor engineered for precise, contactless detection on pneumatic grippers, notably the DHWS-10 series. Providing a continuous analog output signal, it allows advanced automation systems to accurately evaluate gripper jaw positions when paired with external signal converters. Built for industrial environments, it features an IP65 protection rating, a durable PUR housing, and a 0.5-meter TPE-U (PUR) cable terminated with an industry-standard 4-pin M8x1 connector. Operating reliably across temperatures from 5 °C to 60 °C, this sensor is RoHS-compliant and free of copper and PTFE, ensuring compatibility with sensitive manufacturing operations.

Key Features

  • Contactless position detection utilizing the Magnetic Hall principle [1.8]

Industrial Applications

1. Robotic End-Effector Jaw Monitoring

Utilizing the continuous analog output of the position sensor, the unit monitors the angular position of pneumatic gripper jaws during pick-and-place operations. This ensures precise part gripping verification without physical contact.

Problem Solved

Prevents dropped components and process errors by allowing the control system to dynamically verify that the gripper jaws have successfully clamped onto the target object.

2. Automated Assembly Tolerance Inspection

In precision assembly where components vary slightly in size, the sensor provides analog feedback on gripper jaw closure. This allows the PLC to evaluate dimensional tolerances of the grasped component based on the exact resting position of the pneumatic gripper.

Problem Solved

Eliminates the need for a secondary vision inspection station by measuring the part dimensions indirectly through the resting stroke position of the pneumatic gripper.

3. Material Handling in Contaminated Environments

Deployed on automated sorting lines, this sensor performs reliable position detection even when exposed to industrial debris. Its IP65-rated PUR housing and moderate corrosion resistance ensure long-lasting operation without ingress failure.

Problem Solved

Solves the problem of optical sensor fouling in dusty or mildly wet environments by utilizing resilient magnetic field detection combined with a tightly sealed enclosure.
