SECO-LARM - SS-040Q/W - White Vibration Shock Sensors

Product Overview

The SECO‑LARM SS‑040Q/W is a mini shock/vibration detector designed for closed‑circuit alarm systems, featuring adjustable sensitivity (1‑50g contact pressure) to adapt to various surfaces, including walls, windows, ceilings, safes, and cabinets. It includes pure silver contacts with gold plating for reliable long‑term operation, a built‑in tamper switch for added security, and a compact ABS housing for discreet installation. The white‑finish unit operates from -40°C to 75°C, mounts easily with double‑sided tape, and is sold in multiples of 10 pieces.

• • Contact rating: 1A @ 50VDC
• • Contact pressure: Adjustable 1-50g (recommended 5-25g, supplied at ~6g)
• • Contact break time: ~45ms max (at 6g pressure)
• • Estimated life: Over 100,000 cycles
• • Dimensions: 60 × 21 × 15 mm; weight: 20g

Key Features

The SS‑040Q/W is a vibration/shock sensor that detects forced entry attempts — such as hammer, saw, or crowbar impacts — on protected surfaces. When a significant impact occurs, the N.C. contact momentarily opens, triggering the alarm. The built‑in tamper switch, independently wired, provides additional security against removal attempts.

Technical Context

The sensor features adjustable contact pressure (1‑50g, supplied at ~6g) to adapt to different surface types — glass, wood, steel, plasterboard, or brick — with lighter settings for glass and heavier for solid walls. It mounts easily with double‑sided adhesive tape and comes in a discreet, dust‑tight ABS case.

Installation Notes

The unit measures 60 × 21 × 15 mm and weighs 20g, with pure silver contacts with gold plating for reliable long‑term operation, rated at 1A @ 50VDC. It operates from -40°C to 75°C with 5‑90% RH, is available in white (SS‑040Q/W) or brown (SS‑040Q), and is sold in multiples of 10 pieces.
